What Is Shadow AI? Definition, Examples, Risks, and How to Manage It

AI adoption can spread through an organization much faster than security, compliance, and governance teams can see or control it.

Shadow AI is the use of artificial intelligence tools, applications, models, features, or agents for organizational work without sufficient approval, visibility, or governance.

It is what happens when employees turn to AI to solve real work problems before formal controls catch up, and it is why a simple prompt, browser extension, coding assistant, meeting bot, or autonomous agent can quietly become a privacy, security, compliance, or business risk.

The issue has moved well beyond employees casually using public chatbots. Generative AI is now embedded in productivity software, development environments, browsers, meeting platforms, SaaS products, analytics tools, and autonomous agents. A worker may introduce AI into a workflow without even thinking of the activity as deploying a new technology.

That makes Shadow AI particularly difficult to govern. Organizations may have strong cybersecurity programs, vendor review procedures, privacy policies, and AI governance committees yet still lack a reliable view of how employees are using AI during ordinary work.

IBM's Cost of a Data Breach Report 2025 found that 63% of surveyed organizations lacked AI governance policies designed to manage AI or prevent Shadow AI. IBM also reported that organizations with high levels of Shadow AI experienced about $670,000 more in average breach costs than organizations with low or no Shadow AI.

Shadow AI is therefore not simply an IT policy issue. It is an enterprise governance problem involving information security, privacy, intellectual property, human oversight, vendor management, regulation, and accountability.

In this blog, you will learn what Shadow AI is, where it appears in the workplace, why employees use it, the risks it creates, and how organizations can detect, assess, and manage it without blocking useful AI adoption.

Key Takeaways

• Shadow AI includes more than unauthorized chatbots, covering AI assistants, browser tools, APIs, embedded features, and autonomous agents.

• Lack of visibility makes it difficult to manage data, security, privacy, vendors, and legal risks.

• Shadow AI can create data leakage, cybersecurity, privacy, IP, accuracy, and accountability risks.

• Employees often use unapproved AI tools for speed, convenience, and productivity, not malicious reasons.

• Effective governance requires approved tools, clear policies, quick reviews, AI literacy, and monitoring.

• A risk-based approach is essential, with greater scrutiny for AI handling sensitive data or high-impact decisions.

What Is Shadow AI?

Shadow AI refers to AI technology being used for organizational purposes outside the visibility or control of established governance processes.

The important part of that definition is not whether the technology itself is good or bad. The issue is whether the organization knows about the AI use, understands what information it processes, has assessed its risks, and has established appropriate controls.

A public AI chatbot used through a personal account may be Shadow AI. So may an unapproved coding assistant, AI browser extension, generative AI API, image-generation platform, résumé screening application, local language model, or AI meeting recorder.

Increasingly, Shadow AI also includes autonomous or semi-autonomous agents.

Microsoft describes its current Shadow AI capabilities as tools intended to help administrators discover, monitor, and govern unmanaged AI agents being used within organizations. This reflects how the meaning of Shadow AI is evolving as AI moves beyond answering prompts and begins interacting with other systems. That distinction matters.

A chatbot may summarize a document and return text. An AI agent may be allowed to search cloud storage, read email, access customer information, update records, work with code repositories, schedule tasks, or trigger automated workflows.

The more permissions an AI system receives, the greater the potential impact of poor governance.

Shadow AI vs Approved AI

The same AI product can be approved in one organization and considered Shadow AI in another.

If an organization has assessed a system, reviewed the vendor, established data handling rules, configured enterprise controls, trained employees, assigned ownership, and defined permitted uses, that system is operating under governance.

If an employee begins using the same platform through a personal account without review and submits confidential company information, the activity may become Shadow AI.

The distinction is therefore organizational, not technological.

Shadow AI vs Shadow IT

Shadow AI developed from the older concept of Shadow IT, but artificial intelligence introduces additional concerns.

Traditional Shadow IT might involve an employee storing a document in an unauthorized cloud service.

Shadow AI can involve the employee giving that same document to a model, asking it to interpret the contents, generating new material from the information, or connecting the model to other business systems.

That introduces questions about model behavior, output accuracy, human oversight, permissions, confidentiality, and responsibility that conventional software controls were not designed to answer alone.

Shadow AI Examples in the Workplace

Shadow AI is easy to overlook because it often appears inside ordinary tasks.

A marketing employee may upload an unpublished strategy document to a public generative AI service and ask it to create campaign messaging. The worker sees a productivity shortcut. The organization may see confidential commercial information being processed by an unreviewed third party.

A developer may use a personal AI coding assistant to troubleshoot proprietary software. If sections of internal code are transmitted to an external model, intellectual property and security risks can arise even when the employee's only intention is fixing a bug faster.

An HR employee may use an AI service to summarize résumés or compare job applicants. This can introduce personal data processing, bias, accuracy, and employment compliance concerns. The consequences become more serious if AI output influences who receives an interview or employment opportunity.

A finance analyst may upload a spreadsheet containing transaction data to an AI analysis platform. Even if the resulting analysis is useful, the company may not know where the data was stored, how long it was retained, or whether the provider's security and contractual protections meet organizational requirements.

A legal team member might use a public chatbot to summarize a confidential agreement. The system could receive commercially sensitive terms, client information, or legally privileged material without an approved process.

A salesperson may install an AI browser extension that connects with email or a CRM platform. The extension may gain access to customer conversations, contact information, contracts, or sales data that were never intended to leave the approved technology environment.

A meeting assistant can create similar concerns. Recording conversations, producing transcripts, identifying speakers, and generating summaries may involve employee, customer, or confidential information. When the application has not undergone review, the organization may have little visibility into storage, consent, retention, or secondary processing.

AI agents raise the stakes again.

An employee might build an agent that reads messages, retrieves internal files, interacts with project systems, or performs repetitive operational tasks. The agent may produce real business value while simultaneously having broader access than anyone has formally reviewed.

These situations show why risks of Shadow AI depend on context.

Using AI to improve a sentence of publicly available text creates a very different risk profile from allowing an autonomous agent to access employee records, customer databases, or financial systems.

The question should therefore never be only, "Is someone using AI?"

The more useful question is, "What is this AI doing, what information can it access, and what happens if it fails?"

Shadow AI Case Study: Samsung's Generative AI Data Leak

The Samsung incident remains one of the clearest illustrations of how ordinary workplace AI use can create a serious governance problem.

In 2023, Samsung reportedly discovered incidents in which employees had provided sensitive internal information to ChatGPT. Reporting indicated that one employee used the system to check proprietary source code, while another used AI in connection with internal meeting information. Samsung then temporarily restricted generative AI tools on company-owned devices while it worked on creating a safer environment for employee AI use.

The incident is useful because the employees were not reportedly trying to steal company information.

They were trying to work.

A developer wanted AI assistance with code. Another worker wanted help processing meeting material. The business need was understandable, but the information crossed into an external AI environment without sufficient organizational control.

That is why treating Shadow AI purely as employee misconduct misses the underlying problem.

If workers believe an AI system can solve a difficult task quickly, some will use it. Organizations therefore need to provide clear guidance before the employee faces that decision.

Samsung's response also illustrates an important distinction between temporary restriction and long-term governance. According to the company's statement reported by TechCrunch, Samsung was reviewing measures to create a secure environment in which generative AI could be used while improving productivity.

The lesson is not that organizations should reject generative AI.

It is that useful AI should be introduced through environments where data handling, permissions, accountability, and security are understood.

What Are the Risks of Shadow AI?

Shadow AI creates risk because it removes visibility from activities that may involve sensitive data, consequential decisions, external vendors, and powerful system permissions.

The risks are also interconnected.

One unapproved AI interaction may expose confidential information, process personal data, violate contractual terms, produce an incorrect conclusion, and create a cybersecurity weakness at the same time.

Data Leakage and Confidential Information

Data leakage is one of the most immediate Shadow AI risks because generative AI requires information to produce useful output.

Employees may submit customer records, proprietary source code, employee information, financial reports, contracts, product plans, research, internal policies, security information, or strategic documents as part of a prompt.

The employee may be thinking about the response, not the data transfer.

Once the information enters an external AI system, the organization needs answers to several questions. Where is the data processed? How long is it retained? Who can access it? Does the vendor use subprocessors? Are enterprise privacy settings different from consumer accounts? Can the data be deleted? Does the provider use interaction data to improve its services? Are international transfers involved?

Those answers may vary significantly between vendors and account types.

Shadow AI removes the organizational review that would normally examine them.

IBM's 2025 breach research highlights the financial importance of this gap. Among the organizations studied, 63% reported having no AI governance policies to manage AI or prevent Shadow AI. IBM also found that a high level of Shadow AI added approximately $670,000 to the global average breach cost.

Shadow AI and Data Privacy

Shadow AI and data privacy become closely connected whenever employees process personal information through AI services that have not been evaluated.

An organization may not know which personal data has been submitted, which vendor received it, where processing occurred, how long it will remain available, or whether contractual safeguards are in place.

The issue becomes particularly complex for global organizations because privacy requirements vary across jurisdictions.

A multinational employer may need to consider the GDPR in Europe, privacy rules across U.S. states, Brazil's LGPD, Canadian privacy obligations, and requirements throughout Asia-Pacific and other markets.

Sector-specific rules can add further complexity for healthcare, financial services, insurance, education, telecommunications, government, and other regulated activities.

A global Shadow AI policy should therefore begin with organizational controls rather than one country's law.

Companies need clear information classifications, approved AI environments, restricted data categories, vendor standards, and escalation rules. Legal teams can then map local requirements onto those controls.

Privacy governance becomes far more difficult when nobody knows an AI tool is being used.

Shadow AI Cybersecurity

Shadow AI cybersecurity risks extend beyond accidental data exposure.

Generative AI applications can introduce threats that conventional software security programs may not fully address.

The current OWASP GenAI LLM Top 10 2026, published in August 2026, identifies major security risks affecting applications powered by large language models and reflects emerging threats in modern AI environments.

One important concern is prompt injection.

An AI system may process websites, emails, files, messages, or other content containing instructions designed to manipulate the model's behavior.

The risk increases when AI can use tools or interact with other systems.

A chatbot that returns a misleading paragraph may create an accuracy problem. An agent that has permission to retrieve confidential files, send messages, modify records, or interact with production systems can create a far greater security issue.

This makes established cybersecurity controls even more important.

Identity management, least privilege, access reviews, logging, secure configuration, vendor security assessment, endpoint controls, and incident response remain essential. AI introduces new attack paths, but it does not eliminate the need for proven security fundamentals.

Unapproved tools are particularly dangerous because those controls may never have been applied.

Intellectual Property and Trade Secrets

Employees may expose valuable intellectual property to AI systems without realizing that the information should never have left an approved environment.

Source code is an obvious concern, but the category is much broader.

Product designs, algorithms, formulas, research, acquisition plans, pricing strategies, customer lists, training materials, internal processes, technical specifications, strategic documents, unpublished creative work, and business forecasts can all carry commercial value.

The problem is partly a policy communication issue.

"Do not upload confidential information to AI" may sound clear to legal and compliance teams while remaining vague to employees.

A developer may know a customer database is confidential but be unsure whether a small section of proprietary code receives the same protection.

A marketer may understand that customer payment information is restricted but not recognize an unpublished launch strategy as sensitive.

A strong AI policy connects existing information classifications directly to AI use.

Employees should know which categories of information can be used with approved AI tools, which require additional safeguards, and which must not be submitted at all.

Hallucinations, Inaccuracy, and Decision Risk

Shadow AI can cause harm even when no information leaves the organization.

Generative AI can produce incorrect statements, invented references, flawed reasoning, inaccurate calculations, and misleading conclusions while presenting them in confident language.

The business risk depends on where that output goes next.

Incorrect wording in an internal brainstorming document may have little impact.

Incorrect AI output used in a legal analysis, compliance decision, financial report, employment recommendation, security configuration, healthcare process, or customer communication may have serious consequences.

NIST's Generative Artificial Intelligence Profile was developed as a companion to the AI Risk Management Framework and addresses risks that are unique to or intensified by generative AI. It provides suggested actions to help organizations govern, map, measure, and manage those risks.

Human review should therefore reflect consequence.

Organizations do not need the same validation process for every AI-generated sentence. They do need stronger verification where an inaccurate output could affect people, legal obligations, money, safety, security, or significant business decisions.

Shadow AI is particularly problematic because reviewers may not know AI contributed to the work at all.

Regulatory and Compliance Risk

Shadow AI is not itself a universal legal category.

There is no single global law making all unauthorized AI use unlawful.

However, Shadow AI can create exposure under existing privacy, employment, anti-discrimination, intellectual property, consumer protection, cybersecurity, contractual, professional, and sector-specific requirements.

AI-specific regulation adds another layer.

The EU Artificial Intelligence Act establishes obligations based on factors including the type of AI system and the organization's role in providing or deploying it.

This is where Shadow AI and the EU AI Act intersect.

Shadow AI is not automatically prohibited by the Act. The challenge is that an organization cannot determine which obligations apply if it does not know an AI system exists or how employees are using it.

A company cannot accurately classify an AI use case it has never identified.

It cannot document responsibilities for a system nobody formally owns.

It cannot evaluate whether appropriate oversight exists if the activity is happening outside governance.

Visibility is therefore a prerequisite for compliance.

Vendor and Supply-Chain Risk

An AI product may appear to be one application while depending on several external providers

The user-facing service may rely on a third-party foundation model, external cloud infrastructure, plug-ins, APIs, data processors, or other AI services.

When employees independently adopt these products, normal procurement and vendor assessment can be bypassed.

Organizations may therefore lack information about security controls, subprocessors, model providers, data locations, contractual terms, service changes, retention, incident notification, or business continuity.

The risk also exists in software that was originally approved.

A SaaS provider may add generative AI features months after the original security review. Employees start using the new functionality even though the organization never assessed how the feature processes data or what model provider sits behind it.

AI vendor review should therefore continue throughout the lifecycle.

Approval in 2024 does not automatically mean every AI capability introduced in 2026 has been assessed.

Lack of Accountability and Auditability

When an AI-related incident occurs, investigators need evidence.

They need to know which system was used, who used it, which account was involved, what data was submitted, which permissions the system had, what output it produced, whether someone reviewed that output, and who ultimately acted on it.

Shadow AI makes those questions harder to answer.

There may be no formal owner, approval record, risk assessment, logging requirement, or documentation.

That makes accountability one of the less visible but most important risks.

AI governance depends on being able to trace significant systems and decisions.

Without ownership and documentation, shared responsibility can quickly become no responsibility.

How to Manage Shadow AI

Managing Shadow AI does not mean eliminating every AI tool employees discover.

The goal is to convert unknown and uncontrolled AI activity into visible, assessed, and appropriately governed use.

That requires technology, policy, risk management, employee education, and business leadership working together.

Discover Where AI Is Already Being Used

The first step is visibility.

Organizations cannot detect and control Shadow AI if they only maintain a list of officially purchased AI systems.

Start with an AI inventory that includes both approved technology and tools employees are using informally.

The inventory should capture the system name, vendor, business purpose, users, owner, information processed, integrations, permissions, model where known, and risk level.

Employee disclosure matters because technical discovery will not reveal every situation.

Workers should have a simple way to identify AI tools they already find useful without assuming disclosure will automatically lead to punishment.

Technical controls can supplement that process through SaaS discovery, network monitoring, endpoint management, browser controls, identity records, cloud security tooling, API monitoring, procurement information, software subscriptions, and expense records.

Agent discovery is becoming increasingly important as autonomous AI spreads. Microsoft's Shadow AI capabilities specifically focus on detecting and governing unmanaged AI agents, showing how enterprise governance is moving beyond simple website blocking.

The objective is not surveillance for its own sake.

The organization needs enough visibility to understand where meaningful exposure exists.

Assess Risk Before Deciding What to Block

Discovery should lead to assessment, not automatic prohibition.

Different AI uses produce different levels of risk.

A tool used to rewrite publicly available marketing copy is not equivalent to an AI system analyzing medical data.

An assistant producing internal brainstorming ideas is not equivalent to a system ranking job applicants.

A chatbot with no connected systems is not equivalent to an autonomous agent with access to email, cloud files, customer databases, or production code.

A structured AI risk management process helps organizations evaluate those differences. The NIST AI RMF is particularly useful because it is voluntary, cross-sectoral, and designed to help organizations manage risks associated with the development, deployment, and use of AI.

A useful assessment considers the purpose of the AI, data involved, affected individuals, business consequence, model behavior, vendor, integrations, access permissions, human oversight, security controls, legal context, and potential failure modes.

Organizations can then classify use according to risk.

Low-risk AI may be approved with basic conditions. Moderate-risk systems may require enterprise accounts, stronger data restrictions, vendor review, logging, or additional human verification. Higher-impact AI may require formal privacy review, security testing, legal analysis, documented oversight, senior approval, and continuous monitoring.

Some uses should be prohibited.

The key is proportionality.

Establish Clear Shadow AI Governance

Strong Shadow AI governance requires cross-functional ownership.

AI affects too many areas to sit with one department.

IT can manage infrastructure. Cybersecurity can assess technical threats. Privacy teams can evaluate personal data. Legal and compliance teams can interpret obligations. Procurement can manage suppliers. HR can support workforce policies and training. Business units understand why employees need the technology.

These functions need a shared decision model.

The organization should define who approves AI tools, who determines risk levels, who reviews privacy and security concerns, who owns each AI system, who handles incidents, and who has authority to stop unsafe use.

This should connect with the broader AI governance framework rather than becoming a separate Shadow AI bureaucracy.

AI Governance Courses provides a deeper overview of how policies, ownership, inventories, risk assessment, oversight, documentation, and monitoring fit together in its AI Governance Frameworks Explained guide.

Governance also needs to move at a realistic business speed.

If employees need six weeks to approve a low-risk productivity tool that can be accessed publicly in thirty seconds, the process itself becomes a driver of Shadow AI.

Review should be faster for low-risk uses and more rigorous where consequences are greater.

Create an Approved AI Catalog

Employees need alternatives to unauthorized AI.

An approved AI catalog gives them a clear place to start.

The catalog should identify which AI systems can be used, which business purposes they support, what information may be entered, what restrictions apply, and whether additional approval is required for particular use cases.

This turns governance into something employees can use during daily work.

It also reduces repetitive review.

If a writing assistant has already been approved for non-confidential marketing content, another employee performing the same activity should not need to restart the entire vendor assessment.

The catalog should remain dynamic because AI products change rapidly.

A tool may be approved for one use but not another.

A platform approved for drafting may not be approved for automated decision-making.

A system approved to process public information may not be approved for confidential customer records.

Approved does not mean unrestricted.

Introduce an AI Acceptable Use Policy

An AI acceptable use policy should answer operational questions rather than repeat broad principles.

Employees need to know what systems they may use, whether personal accounts are permitted, which information is prohibited, when AI-generated output requires verification, which activities require approval, and how incidents should be reported.

The policy should also address high-impact decisions.

If employees may use AI to draft job descriptions but not automatically reject candidates, that distinction should be clear.

If developers may use an enterprise coding assistant but cannot submit security credentials or restricted code to public models, state that directly.

If AI-generated legal or compliance information must receive qualified human review, make the rule specific.

Good policy reduces ambiguity.

Employees should not need to interpret abstract language every time they open an AI tool.

Strengthen AI Literacy

AI literacy is one of the strongest controls against Shadow AI because employees make decisions technology alone cannot fully manage.

They decide which tool to use, what information to enter, whether AI output looks trustworthym  when a result needs verification and whether to connect an AI system to another application.

Training should therefore cover AI capabilities and limitations, hallucinations, confidential information, personal data, cybersecurity, intellectual property, approved systems, human oversight, and incident reporting.

For organizations operating within the scope of European regulation, AI literacy also has direct regulatory relevance.

Article 4 of the EU AI Act requires providers and deployers to take measures supporting AI literacy among staff and others dealing with AI systems on their behalf. The European Commission confirms that the obligation has applied since February 2, 2025, with supervision and enforcement rules applying from August 3, 2026.

The goal is not to turn every employee into an AI engineer.

Employees need enough understanding to recognize when a productivity shortcut may expose data, create an unreliable decision, or require escalation.

Control AI Agents and Permissions

AI agents deserve stricter attention because they can move beyond content generation.

An agent may be able to search files, access email, interact with databases, update systems, call external tools, or execute business processes. That means identity and access management become central to Shadow AI governance.

Each material agent should have an owner. Its permissions should be limited to what it genuinely requires. Credentials should not be unnecessarily shared. Actions should be logged.

High-impact functions should include appropriate approval or human oversight. Access should be reviewed regularly and removed when no longer required. An agent capable of reading twenty systems should not receive that access simply because it makes automation easier. The same least-privilege principle used for human users should apply to AI.

Monitor AI Continuously

AI approval is not permanent.

Models change. Vendors introduce new features. Data practices evolve. Agents gain capabilities. Integrations are added. Employees find new uses for tools that were originally approved for something else.

Continuous monitoring should therefore be part of Shadow AI management.

Organizations need to reassess material changes in vendor behavior, data processing, model providers, system permissions, regulatory obligations, and business use.

Incidents should feed back into the governance process. If employees repeatedly attempt to use one unauthorized application, the organization should ask why.

The answer may be that employees need better training. It may also reveal that approved systems do not meet a real business need. Effective governance learns from both.

Conclusion

Shadow AI is not fundamentally a chatbot problem.

It is a visibility and governance problem created when employees adopt artificial intelligence faster than the organization can understand, assess, and control it. The risk is growing because AI itself is changing.

Employees are no longer limited to entering text into public chatbots. AI now appears inside productivity software, coding environments, browsers, analytics platforms, meeting tools, SaaS applications, APIs, and increasingly autonomous agents that can interact with business systems.

A hidden writing assistant may expose confidential information. A hidden agent may also hold credentials, permissions, integrations, and the ability to act. That makes blanket prohibition an incomplete long-term strategy.

Organizations need to understand what AI employees are actually using, why they are using it, what information the systems process, what permissions they have, and what could happen if something goes wrong.

From there, governance can become proportionate. Low-risk productivity use can move quickly through approved channels. Higher-impact AI can receive deeper risk assessment, security review, privacy analysis, human oversight, documentation, and monitoring.

The goal is not to eliminate AI experimentation. It is to prevent useful experimentation from becoming invisible enterprise risk.

Organizations that build reliable AI inventories, establish clear ownership, create approved tool catalogs, strengthen AI literacy, apply risk-based review, control agent permissions, and monitor AI throughout its lifecycle are better positioned to benefit from AI without losing accountability.

Shadow AI becomes most dangerous when an organization cannot answer basic questions about the technology already operating inside its business.

What AI are employees using? What information does it process? Who owns the use? What systems can it reach? What could go wrong? What controls are in place?

When those answers become visible, Shadow AI can move from an uncontrolled blind spot into governed AI use.

For professionals responsible for AI risk, compliance, security, or organizational governance, the Shadow AI Risk Management & Governance Course provides focused training on identifying unmanaged AI, assessing its risks, establishing controls, and improving responsible AI oversight.
