How to Use ChatGPT Safely in a Company?

Using ChatGPT safely in a company requires clear rules: use business accounts instead of personal ones, do not paste confidential data into unapproved tools, define prohibited data, manage access, control apps and plugins, enable MFA, train employees and verify AI outputs before business use. ChatGPT can significantly increase productivity, but only when the company has policy, controls and risk awareness.

Short answer

To use ChatGPT safely in a company, the organization should implement an AI usage policy, use a business workspace instead of personal accounts, define prohibited data, enable MFA, control user access, manage apps and plugins, monitor usage, train employees and require verification of outputs before business use. The main risks are confidential data leakage, uncontrolled Shadow AI, incorrect answers, personal data use, unapproved apps and automated actions performed without proper controls.

  • boards
  • business owners
  • CISOs, CTOs and IT directors
  • compliance, legal and risk management teams
  • HR and training leaders
  • sales, marketing and customer support teams
  • finance and administration teams
  • software houses and SaaS companies
  • SMEs adopting AI at work
  • companies using ChatGPT Business or ChatGPT Enterprise
  • organizations that want to reduce Shadow AI, data leakage and wrong AI-driven decision risk

Key takeaways

  1. The safest model for a company is a controlled business workspace, not employees using personal accounts for work tasks.
  2. The most important rule is: do not paste into ChatGPT data that the company would not send to an external provider without agreement, risk assessment and controls.
  3. ChatGPT should not be used as an uncontrolled legal, financial, medical, technical or compliance advisor. Outputs must be verified.
  4. Apps, plugins, connected tools and automated actions increase risk, so they require separate rules, permissions and approvals.
  5. A safe ChatGPT rollout combines AI policy, training, access controls, data rules, monitoring and recurring review of use cases.

Why do companies want to use ChatGPT?

ChatGPT can significantly accelerate knowledge work. Employees use it for writing, analysis, summarization, translation, document preparation, ideation, data organization, coding, offer creation, project planning and learning new topics.

Typical company use cases:

  • drafting emails, offers and presentations
  • summarizing documents and notes
  • translation and language improvement
  • analyzing customer requirements
  • creating checklists and procedures
  • preparing training materials
  • supporting data analysis
  • creating and reviewing code
  • preparing sales scripts, campaigns and webinar concepts
  • supporting research and conceptual work

The problem is not that employees want to use ChatGPT. The problem appears when they do it without rules, without company awareness, without data controls and without understanding AI limitations.

The biggest risks of using ChatGPT in a company

1. Confidential data leakage

An employee may paste customer data, contracts, personal data, source code, technical documentation, sales plans, financial data, NDA-covered data or other confidential information into ChatGPT.

The risk increases if the employee uses a personal account, unapproved tool or does not understand where the data goes and which rules apply to the specific plan.

2. Shadow AI

Shadow AI means using AI tools without company knowledge or approval. This may include a personal ChatGPT account, external application, plugin, transcription tool, AI agent or informal automation process.

Shadow AI is dangerous because the company does not know:

  • which tools are being used
  • which data is being entered
  • who has access to chat history
  • whether data may be used to train models
  • whether the provider meets security requirements
  • whether the employee connected the tool to company email, drive or CRM

3. Incorrect answers and overreliance

ChatGPT may produce answers that sound convincing but are incomplete, outdated, incorrect or not aligned with the company’s context. This is especially important for law, tax, regulation, security, code, medicine, finance and business decisions.

Practical rule: ChatGPT can help prepare an analysis, draft or list of questions, but a responsible person in the company must verify the result.

4. Personal data and confidentiality

Pasting personal data into an AI tool may create legal and organizational risks. This includes data about customers, employees, candidates, patients, users, suppliers and contact persons.

The company should clearly define when personal data may be used in ChatGPT, in which plan, on what basis, for what purpose and with what safeguards.

5. Apps, plugins and connected tools

ChatGPT can connect with apps and data sources. This increases capabilities, but also increases risk. An app may read data, use conversation context and in some cases perform actions in connected systems.

The biggest risks:

  • access to data from company systems
  • overly broad app permissions
  • write actions performed without control
  • lack of clarity on what a third-party app provider can see
  • no review of connected accounts
  • prompt injection risk when working with external content

6. Prompt injection and hidden instructions

Prompt injection occurs when external text, a file, website, email or document contains hidden instructions attempting to influence the model’s behavior. The risk is higher when ChatGPT analyzes internet content, third-party files or data from connected apps.

Companies should be especially careful in scenarios where ChatGPT has access to confidential data and can also send information to external services or perform actions.

The key decision: personal account or business workspace?

Personal account

A personal account may be convenient, but it is not a good model for working with company data. The company does not control access, retention, sharing, history, privacy settings, app connections, employee offboarding or usage rules.

A personal account may be acceptable only for public or neutral data, if company policy allows it.

Business workspace

A business workspace such as ChatGPT Business or ChatGPT Enterprise allows better management of access, users, settings, apps, roles, retention, security and compliance. This is the right direction if the company wants to use ChatGPT regularly at work.

The company should consider a business workspace if:

  • employees use ChatGPT for work tasks
  • customer data or company documents appear
  • the company wants to reduce Shadow AI
  • access and offboarding rules are needed
  • the company has audit or compliance requirements
  • employees use apps, plugins, agents or connected tools
  • the company wants a clear policy and control evidence

Data rule: what should not be pasted into ChatGPT?

The simplest and most important part of an AI policy is the prohibited data list. Employees must know what must not be entered into ChatGPT without company approval.

Data prohibited in unapproved use

  • passwords
  • MFA codes
  • tokens
  • API keys
  • login credentials
  • customer data
  • personal data
  • medical data
  • financial data
  • contracts and confidential documents
  • NDA-covered information
  • source code without approval
  • system architecture documentation
  • production data from company systems
  • non-public strategic, sales or product plans

Usually safer data to use

  • public content
  • texts without personal or confidential data
  • anonymous examples
  • synthetic test data
  • general training questions
  • documents after customer identifiers are removed
  • problem descriptions without technical secrets or sensitive details

Practical employee rule: before pasting data into ChatGPT, ask: could I send this information to an external provider without extra approval?

How to implement ChatGPT safely in a company?

Step 1: assign an AI owner

Without an owner, the topic will be scattered across IT, legal, HR, compliance, sales and business teams. The company should clearly define who owns the rules for using ChatGPT.

The owner should coordinate:

  • AI usage policy
  • approved tool list
  • data rules
  • employee training
  • app and plugin assessment
  • risk monitoring
  • board reporting

Evidence to prepare: AI Security owner decision and responsibility scope.

Step 2: choose the right plan and usage model

The company should decide whether employees may use personal accounts or only a business workspace. For work with company data, a controlled business environment is the better direction.

Check:

  • whether company data is excluded from model training by default
  • how data retention works
  • who can manage users
  • whether MFA, SSO, SCIM or roles are available
  • whether admins can control apps and plugins
  • whether the company needs logs, Compliance Platform, DLP or SIEM integration
  • whether data residency settings are required

Evidence to prepare: decision on the approved ChatGPT plan and personal account rules.

Step 3: prepare a ChatGPT usage policy

The policy should not be long. It should be understandable for employees and address the most common situations.

The policy should define:

  • who may use ChatGPT
  • whether personal accounts are allowed
  • which data is prohibited
  • which use cases are allowed
  • which use cases require approval
  • how outputs must be verified
  • how apps and plugins may be used
  • how AI incidents are reported
  • how AI use is documented at work

Evidence to prepare: company policy for safe ChatGPT use.

Step 4: define allowed use cases

Employees must know what they can use ChatGPT for. If the company only prohibits, people will find workarounds. Clear practical examples work better.

Examples of allowed use:

  • improving email wording without confidential data
  • creating a presentation draft
  • preparing customer question lists
  • summarizing a public article
  • creating a checklist based on public information
  • brainstorming marketing campaign ideas
  • learning technical concepts
  • creating synthetic test data
  • preparing a first draft of a procedure for later review

Examples requiring approval:

  • analyzing a customer contract
  • processing personal data
  • analyzing source code
  • using NDA-covered documents
  • connecting ChatGPT to company drive, email or CRM
  • using an app that performs actions in an external system
  • preparing regulatory or legal content for use without expert review

Evidence to prepare: list of approved and approval-required use cases.

Step 5: manage access and offboarding

Access to company ChatGPT should be managed like access to other important tools. The company should know who has access, what permission level they have and when access is removed.

Minimum baseline:

  • MFA for users and administrators
  • roles: owner, admin, user
  • least privilege
  • access granting process
  • access removal after employee departure
  • regular user review
  • separate admin accounts if the scale justifies it

Evidence to prepare: user and admin list with latest access review.

Step 6: control apps, plugins and connected tools

Apps and plugins can connect ChatGPT with external services, search data, use context and perform actions. This area requires special control.

Before enabling an app, check:

  • what data the app can read
  • what actions it can perform
  • whether it has write actions
  • whether it can send data outside ChatGPT
  • the app provider’s terms and privacy policy
  • whether access can be limited to selected roles or groups
  • whether confirmation can be required before actions
  • whether domains and accounts connected to the app can be restricted

Safest starting model:

  • enable only company-approved apps
  • block unnecessary write actions
  • require confirmation before important actions
  • limit app access by role
  • review connections at least quarterly

Evidence to prepare: register of approved apps, plugins, actions and connections.

Step 7: set rules for GPTs, projects and files

Employees may create their own GPTs, projects, upload files and share materials. This is convenient, but may lead to uncontrolled sharing of company knowledge.

Define rules:

  • who may create custom GPTs
  • whether public GPTs may be used
  • whether GPTs may be published outside the company
  • which files may be uploaded
  • whether files with customer data may be used
  • how long projects and files are retained
  • who is responsible for deleting outdated materials

Evidence to prepare: rules for GPTs, projects and file use.

Step 8: verify ChatGPT outputs before use

ChatGPT can be very helpful, but it should not be the only source of decisions. The company should clearly define which outputs require verification.

Verification is especially required for:

  • legal advice
  • tax advice
  • compliance content
  • regulatory analysis
  • production code
  • security configurations
  • customer-facing answers
  • financial analysis
  • medical content
  • HR decisions about people

Practical rule: ChatGPT can help prepare a draft, but a responsible human approves the final version.

Evidence to prepare: AI output verification rules by task type.

Step 9: train employees with specific examples

Training should show real situations from company work, not only general rules. Employees should be able to distinguish safe use from risky use.

Training should cover:

  • what ChatGPT may be used for
  • what must not be pasted
  • differences between personal and business accounts
  • how to anonymize data
  • how to verify outputs
  • how to use apps and plugins
  • what prompt injection is
  • how to report an AI incident

Evidence to prepare: training materials, participant list and knowledge test.

Step 10: monitor usage and report risk to the board

The company should measure not only the number of users, but also risks, use cases, incidents, policy violations and business value.

Monitor:

  • number of active users
  • most common use cases
  • number of data policy violations
  • AI incident reports
  • number of approved apps
  • number of connected data sources
  • personal account use if the company can detect it
  • business value and time savings

Evidence to prepare: quarterly AI Security board report.

Common company mistakes when using ChatGPT

Mistake 1: no rules and quiet use of personal accounts

If the company does not provide clear rules, employees often start using personal accounts. This creates Shadow AI and lack of data control.

Mistake 2: ban without an alternative

A total ban often fails. Employees will still use AI if they see real value. A safer environment, clear rules and approved use cases work better.

Mistake 3: no prohibited data list

Employees must know whether they can paste a contract, customer data, code, CV or invoice. Without a clear list, decisions will be random.

Mistake 4: overly broad apps and plugins

Connecting ChatGPT to company tools without control may provide access to too much data or allow actions the company did not approve.

Mistake 5: no output verification

ChatGPT may be wrong. Using outputs without verification in legal, finance, code, compliance or customer communication may create business risk.

Mistake 6: no AI incident process

The company should know what to do if an employee pasted confidential data, connected an unapproved app or used an incorrect answer in an important process.

Mistake 7: treating AI only as an IT topic

Safe use of ChatGPT affects IT, security, legal, HR, compliance, sales, the board and employees. It is an organizational topic, not only a technical one.

How to measure safe ChatGPT use?

Adoption metrics

  • number of active users in the business workspace
  • number of teams using ChatGPT
  • number of approved use cases
  • number of trained employees
  • number of submitted safe AI use ideas

Risk metrics

  • number of data policy violations
  • number of AI incidents
  • number of unapproved AI tools
  • number of active apps and plugins
  • number of apps with write actions
  • number of policy exceptions

Control metrics

  • percentage of users with MFA
  • number of workspace administrators
  • date of latest user review
  • date of latest app and plugin review
  • number of use cases with a business owner

Quality metrics

  • number of AI outputs requiring correction
  • number of errors detected before customer delivery
  • number of approved prompt templates
  • number of processes where AI is used with human review

Business example

A consulting company has 60 employees. Employees use ChatGPT for writing emails, summarizing documents, creating offers, analyzing notes and preparing sales materials. The board assumes usage is low, but a quick survey shows that more than half of the team uses personal accounts.

A review shows that fragments of customer contracts, CRM data, meeting notes and NDA-covered content have been pasted into ChatGPT. There was no AI policy, prohibited data list, approved workspace, training or output verification rules.

The company implements a controlled model in 90 days. First, it creates a policy and prohibited data list. Then it launches a business workspace, MFA, training, use case register and app approval process. After 90 days, the board receives the first report: who uses ChatGPT, for what, what the risks are and what must happen next.

The result is not reduced innovation. Employees still use ChatGPT, but they do it more safely, with lower data leakage risk and higher business value.

FAQ

Can ChatGPT be used safely in a company?

Yes, but it requires rules, controls and training. The safest model is a business workspace, clear prohibited data list, MFA, access control, app management and AI output verification.

Can employees use personal ChatGPT accounts for work?

For company data, a company account or business workspace is a better model. A personal account may be allowed only for public or neutral data if company policy permits it.

What must not be pasted into ChatGPT?

Do not paste passwords, MFA codes, tokens, API keys, customer data, personal data, confidential contracts, source code without approval, financial data, NDA-covered data or strategic information.

Can ChatGPT be wrong?

Yes. Outputs may be incorrect, incomplete or not aligned with context. Results must be verified, especially in law, finance, compliance, cybersecurity, code and customer communication.

Are apps and plugins in ChatGPT risky?

They can be risky if they access company data or perform actions in connected systems. The company should approve apps, limit write actions and control connections.

What should happen if an employee pasted confidential data into ChatGPT?

Activate the AI incident procedure: determine data scope, account, plan, conversation, files, recipients, apps, possible legal impact and remediation actions. Fast reporting without hiding the mistake is important.

Can ChatGPT be used to analyze contracts?

It can support analysis, but only under company policy and after data assessment. Contracts often contain confidential information, personal data and NDA-covered data, so using them in ChatGPT requires an approved environment and legal review.

Where should safe ChatGPT rollout start?

Start with current usage inventory, a decision on a business workspace, prohibited data list, short policy, MFA, employee training and a register of approved use cases.

Summary

ChatGPT can be a very valuable business tool, but it should not be deployed chaotically. The biggest risk is not AI itself, but lack of rules: personal accounts, confidential data pasted without control, unapproved apps, no output verification and no incident process.

Safe ChatGPT use requires a simple model: business workspace, AI policy, prohibited data list, MFA, user control, app management, training, output verification and risk reporting to the board.

The best companies do not block AI without an alternative. They give employees a safe way to work, clear rules and practical examples. This allows ChatGPT to increase productivity without creating uncontrolled risk for company data, customers and reputation.

Shadow AI: The Hidden Risk of AI Tools in Organizations

Shadow AI means the use of AI tools in an organization without the company’s knowledge, approval or control. It may include personal AI accounts, unapproved apps, plugins, transcription tools, coding assistants and AI agents. The biggest risks are data leakage, confidentiality breaches, lack of vendor control, wrong decisions, legal issues and missing compliance evidence.

Prepared by: CCyber Editorial Team

Short answer

Shadow AI occurs when employees use AI tools without the organization’s knowledge, approval or control. This usually happens when the company does not provide safe tools, clear rules and a simple approval process. Shadow AI may lead to leakage of customer data, source code, confidential documents, personal data, company secrets and information covered by contracts. The best response is not a ban alone, but visibility, an AI use policy, data classification, approved tools, training, monitoring and an AI incident response process.

  • HR and training teams
  • AI, data science and automation teams
  • software houses and SaaS companies
  • SMEs using AI tools
  • companies using Microsoft 365, Google Workspace, ChatGPT, Copilot, Gemini, Claude or similar tools

Key takeaways

  1. Shadow AI does not necessarily mean employees want to break rules. Most often, it means they are looking for a faster way to work and the company has not provided a safe alternative.
  2. The main risk of Shadow AI is not AI use itself, but lack of knowledge about what data goes into tools, who can access it and whether the vendor meets security requirements.
  3. The highest-risk data includes customer data, personal data, contracts, financial information, source code, secrets, API keys, strategy documents and data covered by NDAs.
  4. A ban alone usually does not work. Companies need approved tools, clear rules, training and an easy process for requesting new AI use cases.
  5. The best start is an inventory of AI use, an acceptable AI use policy, data classification, vendor assessment, access control and risk monitoring.

What is Shadow AI?

Shadow AI means using AI tools in an organization outside official company control. It may involve personal accounts, free tools, browser extensions, mobile applications, transcription tools, coding assistants, presentation generators, chatbots or AI agents without approval from IT, security, compliance or legal teams.

Shadow AI is similar to Shadow IT, but the risk can be higher. With Shadow IT, an employee may store files in an unapproved application. With Shadow AI, an employee may enter data into a system that analyzes, processes, summarizes, stores it in chat history, uses it in integrations or passes it further through plugins and external connections.

Examples of Shadow AI:

  • an employee pastes a customer contract into a public AI chatbot
  • a developer sends source code to an unapproved coding assistant
  • a manager uses a personal AI account to analyze employee data
  • sales uses an AI tool to analyze call recordings without vendor assessment
  • HR uses AI to screen CVs without risk and compliance review
  • an employee installs an AI browser extension with access to company documents
  • a team uses a meeting transcription tool without checking where recordings go
  • someone creates an AI agent with access to email, files or CRM without permission control

Why does Shadow AI appear in companies?

Shadow AI appears because AI tools genuinely help employees work faster. Employees do not always want to bypass rules. They often want to write an email faster, prepare an offer, summarize a meeting, translate a document, analyze data or generate code.

Common causes:

  • the company has no approved AI tools
  • the company has tools, but they are too limited or hard to use
  • there are no clear rules on what is allowed and what is prohibited
  • approval of new tools is too slow
  • employees do not know which data is confidential
  • managers expect faster work but do not provide safe tools
  • business teams buy SaaS tools with AI features without consulting IT
  • employees do not understand risks related to chat history, training data, plugins and integrations

In practice, Shadow AI is a signal to the board: people want to use AI, but the organization has not yet created a safe and convenient operating model.

What data most often goes into unapproved AI tools?

Customer data

Employees may paste customer requests, contracts, correspondence, call recordings, project data, requirements, complaints or implementation documents into AI.

Personal data

AI tools may receive data about employees, candidates, customers, patients, users or contractors. This may create personal data protection risk.

Source code and technical data

Developers may send code fragments, logs, errors, configurations, secrets, API keys, database queries or diagnostic data to AI.

Confidential and strategic information

AI is often used to summarize strategy, sales plans, board documents, financial information, product roadmaps or business secrets.

Contract-protected data

Customer data, technical documentation, contract terms, project information and materials covered by NDAs should not go into tools without checking the legal basis, contract and processing rules.

The most important Shadow AI risks

1. Confidential data leakage

The most obvious risk is entering information into an AI tool that the company should not share with an external provider. This may include a contract, customer data, code, strategy document, financial information or technical secrets.

The problem is that the company may not know that such a data transfer happened. If the tool is used through a personal account, outside company control, it is hard to determine data scope, activity history and accountability.

2. Personal data protection issues

If an employee enters personal data into an unapproved AI tool, the company may not know who the provider is, where data is processed, how long it is stored, whether it is used to improve the service and whether the right data processing agreement exists.

3. Exposure of code, secrets and technical information

In technical teams, Shadow AI may lead to leakage of source code, API keys, tokens, configuration files, logs, database schemas and system architecture information.

This risk is especially important for software houses, SaaS companies and digital product manufacturers because code and architecture are part of business value and product security.

4. Lack of vendor control

An AI tool may look like a simple application, but behind it there is a vendor, models, infrastructure, subcontractors, data storage, terms of use and security posture. Without vendor assessment, the company does not know whether the tool meets security, privacy and compliance requirements.

5. Wrong decisions based on AI output

AI may generate answers that are convincing but incorrect. If an employee uses output without verification, the company may make a wrong legal, financial, technical, HR, sales or operational decision.

6. Overreliance on AI

Shadow AI can lead to employees treating AI output as truth. This is dangerous when analyzing contracts, vulnerabilities, code, financial data, HR decisions, customer communications and risk assessments.

7. Risk of AI features embedded in SaaS tools

Shadow AI is not only public chatbots. More SaaS applications include AI features by default. A business team may enable such a feature without IT knowing, and the tool may analyze documents, conversations, support tickets, CRM data or customer history.

8. AI agent risk

An AI agent may take actions, not only return text. If it has access to email, files, CRM, project systems, code repositories or calendars, its permissions should be controlled like the permissions of a technical user.

An unsafe AI agent may perform unauthorized actions, send data, download files, change records or act based on manipulated instructions.

9. Missing audit evidence

The company may have a security policy, but if it does not know which AI tools are used, it has no control evidence. This makes audits, customer discussions, compliance and incident response more difficult.

Shadow AI and prompt injection

Prompt injection is a technique for manipulating a language model application through specially crafted instructions. It may occur when AI processes user content, documents, websites, emails, files or data from external systems.

In the Shadow AI context, the problem is larger because the company may not know:

  • that employees are using an application vulnerable to prompt injection
  • that the tool has access to company data
  • that the tool uses plugins or integrations
  • that AI may perform an action on behalf of the user
  • that there are no logs or monitoring for these actions

Unapproved AI tools should therefore be treated not only as a privacy risk, but also as a cybersecurity risk.

What not to do: banning AI only

The simplest response is banning AI use. In practice, a ban alone often fails. Employees will continue to use tools if they see real value and the company does not provide a safe alternative.

A better approach:

  • understand where and why people use AI
  • approve safe tools for the most common use cases
  • clearly define which data must not be entered into AI
  • create a simple approval path for new tools
  • train employees using examples from their work
  • monitor risks and respond to policy violations

A ban without an alternative creates hiding. Good governance creates visibility.

How to reduce Shadow AI step by step

Step 1: assign an AI Security owner

Shadow AI affects IT, security, legal, data protection, HR, procurement, finance and business teams. Without an owner, the topic will be fragmented.

The owner should coordinate:

  • AI use policy
  • tool inventory
  • vendor assessment
  • risk classification
  • training
  • monitoring and reporting
  • AI incident process

Evidence to prepare: AI Security owner decision, responsibility scope and supporting team list.

Step 2: inventory AI use

You cannot control what you cannot see. The first practical step is determining which AI tools employees use and for what tasks.

Include:

  • AI chatbots
  • transcription tools
  • coding assistants
  • presentation and image generators
  • AI tools in CRM, HR, sales and marketing
  • browser extensions
  • email and document plugins
  • AI in SaaS applications
  • AI agents and automation

Evidence to prepare: AI tool register, business owner, data type, purpose of use and approval status.

Step 3: classify use cases

Not every AI use has the same risk. Improving the style of an email is very different from analyzing customer data, source code, CVs, medical documentation or contracts.

Example classification:

  • low risk: language correction without confidential data
  • medium risk: marketing content creation without customer data
  • high risk: analysis of customer data, contracts, code, personal data or confidential documents
  • critical risk: AI with access to systems, decisions, sensitive data or automated actions

Evidence to prepare: AI use case register with risk rating.

Step 4: define data prohibited in AI tools

Employees need to know what must not be entered into unapproved AI tools.

The prohibited list should include:

  • passwords
  • API keys
  • tokens
  • customer and employee personal data
  • medical and financial data
  • contracts and confidential documents
  • business secrets
  • source code without approval
  • data covered by NDAs
  • non-public financial data
  • customer data without a legal and business basis

Evidence to prepare: data classification rules and prohibited data list for unapproved AI tools.

Step 5: approve safe AI tools

The company should create a list of AI tools allowed for work. Employees should know which tool they can use for which task.

The approved tool list should show:

  • tool name
  • allowed use cases
  • prohibited data
  • business owner
  • terms of use
  • whether data may be used to train models
  • whether an enterprise version is available
  • whether access uses a company account
  • whether logging and access control are enabled

Evidence to prepare: approved AI tool list and usage rules.

Step 6: assess AI vendors

An AI vendor should be assessed like any important technology provider. The company should know where data is processed, how long it is stored, who can access it and which contractual terms apply.

Check:

  • data processing location
  • prompt and output retention
  • use of data for training or service improvement
  • provider administrator access
  • subprocessors
  • contractual terms and DPA
  • security certifications or reports
  • incident handling
  • data deletion options
  • enterprise features such as SSO, MFA, logs and access control

Evidence to prepare: AI vendor assessment, approval decision and usage terms.

Step 7: manage access to AI tools

AI tools should be managed like other company systems. Access should be granted, reviewed and removed when an employee leaves.

Minimum baseline:

  • company account login
  • MFA
  • roles and permissions
  • user list
  • access granting and removal process
  • separate administrator permissions
  • usage logs
  • access review at least quarterly

Evidence to prepare: AI tool user list, roles, MFA configuration and latest access review.

Step 8: monitor data movement

The company should monitor whether confidential data is sent to unapproved AI tools. This is not about reading every employee conversation, but about visibility into data movement and responding to policy violations.

Possible controls:

  • data loss protection
  • cloud application monitoring
  • browser extension control
  • blocking high-risk tools
  • alerts for personal data, code, secrets and confidential documents
  • AI tool usage logs
  • exception and violation reviews

Evidence to prepare: AI monitoring report, violation list and corrective actions.

Step 9: introduce rules for AI agents

AI agents need separate rules because they can perform actions in systems. They should not have more permissions than necessary.

Control:

  • which systems the agent can read
  • which systems the agent can change
  • whether the agent can send messages
  • whether the agent can download files
  • whether high-risk actions require human approval
  • whether actions are logged
  • whether agent permissions are reviewed

Evidence to prepare: AI agent register, permission scope, action logs and human approval points.

Step 10: train employees with practical examples

Shadow AI training should be practical. Employees need examples from their work, not generic slides about artificial intelligence.

Training should cover:

  • what Shadow AI is
  • which data is prohibited
  • how to use approved tools
  • how to verify AI outputs
  • how to request a new AI tool
  • how to report an AI incident
  • how to recognize deepfake and AI-enabled fraud risk
  • how to use AI safely in everyday work

Evidence to prepare: training materials, attendee list, knowledge test and confirmation of policy acceptance.

Step 11: prepare an AI incident process

The company should know what to do if an employee pasted confidential data into an unapproved tool, an AI agent performed an unwanted action or an AI tool disclosed data.

The process should define:

  • where to report an AI incident
  • who assesses the data scope
  • who contacts the vendor
  • who assesses legal obligations
  • who decides on customer communication
  • how evidence is preserved
  • how access is removed or tool use is stopped
  • how recurrence is prevented

Evidence to prepare: AI incident procedure and AI incident or policy violation register.

Step 12: report risk to the board

Shadow AI should be visible to the board because it affects data, compliance, reputation, vendors and work efficiency. The report should not be technical. It should show risk and decisions.

The report may include:

  • number of approved AI tools
  • number of unapproved AI tools
  • most common AI use cases
  • number of policy violations
  • most common risky data types
  • training status
  • key decisions required
  • 90-day action plan

Evidence to prepare: quarterly AI Security board report.

Common Shadow AI mistakes

Mistake 1: total ban without an alternative

If employees need AI for work, a ban alone usually moves use to personal accounts and unapproved tools. A better approach combines rules, approved tools and monitoring.

Mistake 2: no prohibited data list

Employees often do not know whether they can paste a contract, CV, customer data, code fragment or internal document into AI. Without a clear list, they will decide on their own.

Mistake 3: treating AI only as an IT topic

Shadow AI affects legal, data protection, HR, procurement, sales, customer support and the board. IT alone cannot solve the problem without business support.

Mistake 4: ignoring AI in SaaS tools

A company may block public chatbots while still using AI features in CRM, HR, marketing, customer support and document systems. These features also require assessment.

Mistake 5: no control over AI agents

An AI agent with system access should have limited permissions, logs, approval points and an owner. It should not operate like an invisible unmanaged user.

Mistake 6: no process for requesting new tools

If the approval process is unclear or too slow, employees will use tools without approval. The process should be simple, fast and understandable.

Mistake 7: no evidence

The company may have good intentions, but without a tool register, vendor assessments, training, logs and reports, it is difficult to show customers or auditors that AI is under control.

How to measure Shadow AI risk?

Visibility metrics

  • number of detected AI tools
  • number of approved AI tools
  • number of unapproved AI tools
  • number of departments using AI
  • number of AI use cases in the register

Data metrics

  • number of data policy violations
  • number of attempts to send confidential data to AI
  • number of incidents involving personal data
  • number of AI tools with access to files, email or CRM
  • number of AI policy exceptions

People metrics

  • percentage of trained employees
  • AI Security knowledge test score
  • number of new AI tool requests
  • time to approve a new AI tool
  • number of questions and consultations about AI

Governance metrics

  • number of assessed AI vendors
  • number of tools with SSO and MFA
  • number of AI incidents
  • AI incident response time
  • number of AI Security board reports

Business example

A services company has 180 employees. Employees use AI to write offers, translate emails, summarize meetings, analyze contracts and create marketing content. The board believes the company does not officially use AI because it has not bought any enterprise AI tool.

A short assessment shows that employees are using more than a dozen AI tools through personal accounts. Contract fragments, customer data, meeting notes, candidate CVs, code and proposal documents have been entered into these tools. There is no tool list, no vendor assessment, no AI policy and no training.

The problem is not that employees want to use AI. The problem is that the company has not provided them with a safe operating model.

Within 90 days, the company creates an approved tool list, prohibits confidential data in unapproved tools, assesses vendors, enables company login, trains employees and creates a process for requesting new AI tools.

After implementation, the company does not block innovation. Employees still use AI, but in a more controlled way, aligned with risk and explainable to customers and auditors.

FAQ

What is Shadow AI?

Shadow AI is the use of AI tools in an organization without the company’s knowledge, approval or control. It may include personal AI accounts, public chatbots, browser extensions, transcription tools, coding assistants and AI features in SaaS applications.

Is Shadow AI always bad?

Not every AI use is bad. The problem is lack of control over the tool, data, vendor, permissions and outputs. The goal should not be blocking AI, but managing AI use safely.

Which data is most risky?

The highest-risk data includes customer data, personal data, financial data, confidential documents, business secrets, non-public financial information, restricted source code, passwords, API keys and technical secrets.

Does banning AI solve the problem?

Usually not. A ban alone may move AI use to personal accounts and hidden tools. A better approach is approved tools, clear rules, training, monitoring and a simple approval process.

Is Shadow AI only about ChatGPT?

No. Shadow AI may include many tools: chatbots, content generators, meeting tools, coding assistants, AI features in SaaS, plugins, browser extensions and AI agents.

How can Shadow AI be detected?

The best approach combines surveys, business team interviews, SaaS application analysis, traffic monitoring to AI tools, procurement review, browser extension control and employee reporting.

How is Shadow AI different from AI governance?

Shadow AI is uncontrolled AI use. AI governance is a system of rules, roles, processes, risk assessments, approvals and monitoring that enables controlled AI use.

Where should Shadow AI reduction start?

The best starting point is an AI tool inventory, AI use policy, prohibited data list, approved safe tools, vendor assessment and employee training.

Summary

Shadow AI is one of the most important new organizational risks because AI entered daily work faster than policies, training and security controls.

The biggest problem is not artificial intelligence itself. The biggest problem is lack of visibility: the company does not know which tools employees use, what data goes into them, who has access and what vendor terms apply.

The best strategy combines security and usability: approved tools, clear rules, data classification, vendor assessment, access control, monitoring, training and board reporting. This allows the company to use AI faster, but without uncontrolled risk.

AI Security for Companies: Where Should You Start?

AI Security does not start with banning artificial intelligence. It starts with an inventory of AI tools, acceptable use rules, data classification, access control, vendor assessment, data leakage prevention, training and monitoring risks such as shadow AI, prompt injection, deepfakes and overreliance on AI outputs.

Prepared by: CCyber Editorial Team

Short answer

Companies should start AI Security with a simple and practical programme: identify which AI tools employees use, what data is entered into them, which processes depend on AI, who approves tools and what controls are required. The first priorities are an acceptable AI use policy, data classification, access control, vendor assessment, employee training, shadow AI monitoring, LLM application security and an AI incident response plan.

Key takeaways

  1. AI Security is not only model security. It also covers data, users, vendors, business processes, applications, integrations and AI-supported decisions.
  2. The biggest early risks are shadow AI, data leakage, prompt injection, overreliance on AI outputs, deepfakes, missing policies and lack of risk ownership.
  3. A company should first inventory AI tools and use cases before buying more solutions.
  4. Safe AI use requires clear rules: which tools are allowed, what data must not be pasted and who approves new AI use cases.
  5. The best start is a 30-day programme: AI inventory, usage policy, data classification, employee training and a quick risk assessment.

What is AI Security?

AI Security means securing systems, processes and data related to artificial intelligence. It includes secure use of ready-made AI tools as well as security of applications, models, integrations, training data, prompts, outputs, AI agents and automation.

In practice, AI Security answers the following questions:

  • which AI tools are employees using?
  • what data is entered into these tools?
  • are AI tools approved by the company?
  • does the AI vendor meet security and privacy requirements?
  • does AI have access to company data, email, documents or systems?
  • do employees know what must not be pasted into AI?
  • are AI outputs verified by humans?
  • does the company have a response plan for AI-related incidents?

AI Security is not about blocking innovation. The goal is to help the company use AI faster, but without uncontrolled risk.

Why should companies address AI Security now?

Artificial intelligence has entered companies faster than many other technologies. Employees use it to write emails, analyze documents, summarize meetings, generate code, prepare offers, translate content, analyze data and support customers.

The problem is that many organizations do not know:

  • who uses AI
  • which tools are used
  • what data is entered
  • whether data is sent to an external provider
  • whether employees understand AI limitations
  • whether AI is part of a decision-making process
  • whether control and approval evidence exists

This creates shadow AI risk, meaning the use of AI tools outside the knowledge and control of the organization. Shadow AI is especially risky when employees paste customer data, personal data, source code, company secrets, contractual documents or financial information into public tools.

Where should AI Security start?

Step 1: inventory AI tools

You cannot secure what you cannot see. The first step is an inventory of AI tools used officially and unofficially.

The inventory should include:

  • ChatGPT, Copilot, Gemini, Claude and other chatbots
  • AI tools in Microsoft 365 or Google Workspace
  • AI in CRM, marketing automation and sales
  • AI in helpdesk and customer support
  • AI in HR and recruitment tools
  • AI in developer tools
  • AI in BI and analytics systems
  • AI in SaaS applications used by business teams
  • custom chatbots, AI agents and LLM applications
  • API integrations with AI models

Evidence to prepare: AI tools register, business owner, vendor, data type, purpose of use and approval status.

Step 2: identify AI use cases

The tool name alone is not enough. What matters more is how the company uses AI. The risk level depends on the use case.

Example use cases:

  • writing emails and documents
  • summarizing meetings
  • analyzing contracts
  • customer support chatbot
  • code generation
  • sales data analysis
  • recruitment and candidate screening
  • customer risk assessment
  • business decision automation
  • AI agents taking actions in systems

Not every use case has the same risk level. AI used to improve the style of an email has a different risk profile than AI used for candidate selection, customer assessment, financial data access or automated action in business systems.

Evidence to prepare: list of AI use cases with risk rating: low, medium, high.

Step 3: define what data must not be used in AI

The biggest starting issue is data. Employees often do not know whether they can paste a contract, customer data, CV, source code, financial report or strategy document into AI.

The company should clearly define what must not be pasted into public or unapproved AI tools.

Commonly prohibited data should include:

  • passwords and secrets
  • API keys
  • personal data of customers and employees
  • medical and financial data
  • company secrets
  • non-public financial data
  • contracts and confidential documents
  • restricted source code
  • data covered by NDAs
  • customer data without a legal and business basis

Evidence to prepare: data classification and rules for using data in AI tools.

Step 4: prepare an acceptable AI use policy

An AI policy does not need to be 50 pages long. At the beginning, it should be short, clear and understandable for employees.

A good policy should answer:

  • which AI tools are allowed?
  • which tools are prohibited?
  • what data can be processed in AI?
  • what data must not be pasted?
  • when is approval from a manager, IT, security or legal required?
  • can AI outputs be sent to customers without review?
  • how should AI-generated content be labelled?
  • how should an incident or suspicious AI behavior be reported?

The policy should be supported by training. A document alone is not enough if employees do not understand examples from their daily work.

Evidence to prepare: AI use policy, employee acceptance confirmation and training materials.

Step 5: assess AI vendors

AI often operates as an external service. This means data, prompts, files, outputs and metadata may be sent to a vendor. The company should understand how the vendor protects data and what contractual terms apply.

When assessing an AI vendor, check:

  • where data is processed
  • whether customer data is used to train models
  • whether training on company data can be disabled
  • how long prompts and outputs are retained
  • who can access the data
  • whether access is logged
  • whether the vendor offers a business or enterprise version
  • whether DPA, SLA and security terms are available
  • whether the vendor has certifications or security reports
  • how incident handling works

Evidence to prepare: AI vendor assessment, accepted contractual terms, DPA and tool approval decision.

Step 6: secure access to AI tools

AI tools should be managed like other business systems. Access should be controlled, monitored and removed when an employee leaves.

Minimum access controls:

  • SSO if supported
  • MFA for users
  • roles and permissions aligned with need
  • user list
  • access granting and removal process
  • separate administrator permissions
  • activity logs
  • access review at least quarterly

If an AI tool has access to email, files, CRM, code repositories or financial systems, it should be treated as a high-risk system.

Evidence to prepare: AI user list, SSO/MFA configuration, roles, administrators and latest access review.

Step 7: secure LLM applications and chatbots

If the company builds its own chatbot, LLM application, AI agent or model API integration, the risks are higher than when using a ready-made tool.

Consider at least:

  • prompt injection
  • data leakage from context
  • unsafe tool use by AI agents
  • excessive application permissions
  • lack of AI output validation
  • poisoning of RAG data
  • lack of customer data separation
  • vulnerabilities in plugins and integrations
  • overreliance on model answers
  • lack of logging for prompts, actions and errors

An LLM application should be treated as high risk if it has access to sensitive data, users, payments, internal systems or can automatically take actions.

Evidence to prepare: AI application threat model, data list, integration list, permission controls, prompt injection tests and activity logs.

Step 8: introduce human-in-the-loop

In many processes, AI should support humans, not replace decisions without control. This is especially important for decisions about customers, employees, finances, security and legal matters.

Human-in-the-loop means that a human:

  • understands the role of AI in the process
  • verifies AI output before use
  • can stop or change a decision
  • knows when AI output is uncertain
  • has access to rationale, input data or sources
  • is responsible for the final decision

The biggest mistake is treating AI output as automatically true. AI can produce convincing but incorrect answers.

Evidence to prepare: decision process description, human role, approval points and AI output verification rules.

Step 9: monitor AI usage and incidents

AI Security does not end with policy and training. The company should monitor whether tools are used according to rules and whether incidents occur.

Monitor:

  • new AI tools used in the company
  • access to approved tools
  • unauthorized integrations
  • attempts to paste sensitive data
  • unusual API usage
  • costs and abuse
  • model errors reported by users
  • incidents involving data, prompts or outputs

For AI applications, it is useful to log prompts, outputs, decisions, tools used and actions performed by the AI agent, while respecting privacy and data minimization principles.

Evidence to prepare: AI incident register, usage logs, alerts and periodic AI risk report.

Step 10: train employees

The best AI policy will not work if employees do not understand how AI can harm the company. Training should be practical and example-based.

Training should cover:

  • what shadow AI is
  • what data must not be pasted into AI
  • how to verify AI outputs
  • how to recognize deepfakes and voice scams
  • how AI supports phishing
  • how to use approved tools
  • how to report AI incidents
  • when to request approval for a new AI use case

Evidence to prepare: training attendance list, materials, knowledge test and refresher schedule.

The most important AI risks for companies

Shadow AI

Shadow AI is the use of AI tools outside the knowledge and control of the organization. It can involve public chatbots, browser extensions, mobile apps, transcription tools, presentation generators or coding plugins.

The risk is that the company does not know what data is sent to the tool, where it is processed and who can access it.

Data leakage

An employee may paste customer data, a contract, personal data, code, a strategy document or financial information into AI. Even if done with good intentions, the company may lose control of the information.

Prompt injection

Prompt injection is an attempt to manipulate an LLM application through specially crafted instructions. It can lead to data disclosure, rule bypass, undesired action or ignoring system instructions.

Unsafe AI agents

An AI agent that can take actions in systems creates higher risk than a chatbot that only returns text. If the agent has access to email, files, CRM, internet, financial systems or code repositories, its permissions must be limited.

Deepfakes and voice scams

AI makes it easier to create fake images, voices and video. This increases the risk of executive impersonation, urgent payment fraud, bank account change fraud and employee manipulation.

Overreliance on AI

AI can generate convincing errors. Overreliance on AI outputs can lead to poor business decisions, legal mistakes, code defects, incorrect data analysis and wrong customer communication.

AI vendor risk

An AI vendor may change terms, model behavior, processing location, data usage or security posture. The company should monitor critical AI vendors like other technology suppliers.

Minimum safe AI use rules for employees

Rule 1: use only approved tools

Employees should know which AI tools are allowed for work. If they want to use a new tool, there should be a simple approval path.

Rule 2: do not paste confidential data

Personal data, customer data, company secrets, passwords, API keys, restricted code and confidential documents should not be pasted into public or unapproved AI tools.

Rule 3: verify AI outputs

AI output should be treated as a suggestion, not as automatic truth. Before using an output in a decision, offer, code, analysis or customer communication, it should be verified.

Rule 4: do not give AI excessive permissions

If an AI tool has access to email, files, CRM, code repositories or production systems, its permissions should be limited to the minimum necessary.

Rule 5: report incidents and errors

Employees should know where to report situations where they pasted the wrong data into AI, a tool behaved suspiciously or AI output caused an error.

Common AI Security mistakes

Mistake 1: banning AI instead of managing risk

A complete AI ban often leads to shadow AI. Employees will still look for tools that help them work faster. A better approach is clear rules, approved tools and training.

Mistake 2: no inventory

A company cannot manage risk if it does not know where AI is used. Inventory is the foundation of every AI Security programme.

Mistake 3: focusing only on the tool, not on data

The key question is not only “which tool do we use?”. The more important question is: what data goes into AI and what impact does AI output have on business decisions?

Mistake 4: no verification of AI outputs

AI can be wrong, and incorrect answers often look convincing. Human verification is required in business processes.

Mistake 5: no control over AI agents

An AI agent with access to systems can take real actions. Without limits, logs and approvals, it can become a new source of operational risk.

Mistake 6: no vendor assessment

AI vendors process data and may become critical to business processes. They should be assessed for security, privacy, contracts, data retention and incident handling.

AI Security, AI Act, ISO/IEC 42001 and NIST AI RMF

AI Act

The AI Act introduces a risk-based approach and distinguishes between prohibited AI systems, high-risk systems, transparency risks and minimal-risk systems. For companies in the EU, this means assessing whether a specific AI use case may be subject to regulatory requirements.

ISO/IEC 42001

ISO/IEC 42001 concerns AI management systems. It is useful for organizations that want to structure policies, roles, processes, risks, documentation and continual improvement in AI.

NIST AI RMF

NIST AI RMF helps manage AI risk through the Govern, Map, Measure and Manage functions. It is a practical way to translate AI from broad principles into a risk management process.

OWASP LLM Top 10

OWASP LLM Top 10 helps technical teams understand key LLM application risks, including prompt injection, insecure output handling, data poisoning, model denial of service, supply chain vulnerabilities, sensitive information disclosure, excessive agency and overreliance.

Business example

A service company has 120 employees. Employees use public AI tools to write proposals, analyze contracts, translate documents and generate marketing content. IT does not have a full list of tools, and the board assumes the topic is not urgent because the company does not build its own AI model.

A short assessment shows that employees have pasted customer data, contract fragments, confidential documents and source code into AI tools. Some tools operate as browser extensions, some have access to email and some accounts were created with private email addresses.

The problem is not the use of AI itself. The problem is the lack of rules, risk ownership, data classification, approved tools and access control.

Within 30 days, the company can reduce risk: create an AI tool register, prohibit pasting confidential data into public tools, approve secure enterprise versions, train employees and introduce a process for approving new tools.

The best first step is a short AI Security workshop. It helps quickly determine where the company already uses AI, what data is at risk, which tools need approval and which actions should be implemented first.

FAQ

Should a company ban AI use?

Usually not. A total ban often leads to shadow AI. A better solution is to define approved tools, prohibit confidential data in unapproved systems and train employees.

Where should AI Security start?

The best starting point is an inventory of AI tools, use cases, data classification, acceptable AI use policy and employee training.

What is shadow AI?

Shadow AI is the use of AI tools outside the knowledge and control of the organization. It can include public chatbots, browser extensions, SaaS apps and AI tools used through private accounts.

What data must not be pasted into AI?

Passwords, API keys, personal data, customer data, confidential documents, company secrets, non-public financial data and restricted source code should not be pasted into public or unapproved AI tools.

What is prompt injection?

Prompt injection is a technique that manipulates an LLM application through specially crafted instructions. It can lead to data disclosure, rule bypass, ignored system instructions or unwanted actions.

Does AI Security apply only to companies building their own models?

No. AI Security also applies to companies using ready-made AI tools, chatbots, copilots, SaaS applications with AI features or model integrations through APIs.

Does the AI Act apply to every company using AI?

Not every AI use has the same level of obligations. The AI Act follows a risk-based approach. A company should check whether its AI use is high-risk, requires transparency or falls under specific rules.

How often should AI risks be reviewed?

At least quarterly and whenever a new tool, use case, vendor, system integration or data processing method is introduced.

Summary

AI Security for companies should not start with panic or bans. It should start with visibility, rules and controls. The company must know where AI is used, what data goes into tools, who approves use and what risks are accepted.

The most important first actions are AI tool inventory, acceptable use policy, data classification, employee training, vendor assessment and LLM application security.

Organizations that implement AI Security early will be able to use AI faster, more safely and with greater trust from customers, employees and the board.
