Shadow AI Risk: How to Find AI Use Across the Business

Shadow AI is the use of AI tools, systems, vendors, models, agents, or embedded AI features without formal visibility or governance approval. For regulated institutions, shadow AI creates risk because teams cannot assess, monitor, or prove oversight of AI they do not know exists.

You cannot govern AI you cannot see

Most organizations have more AI use than they realize.

Some AI use is obvious. A business unit may request approval for a new AI platform. A data science team may build a model. A vendor may disclose an AI feature during procurement.

But much of today’s AI use is less visible.

Employees use public AI tools to summarize documents or draft content. SaaS vendors add AI features to products the company already uses. Teams experiment with copilots, assistants, automation tools, and analytics platforms. Vendors change model providers. AI capabilities appear in workflows that were not originally reviewed as AI.

This is shadow AI.

For regulated institutions, the real exposure sits one step further than the existence of shadow AI itself: untracked AI cannot be risk assessed, approved, monitored, reassessed, or proven to auditors, examiners, boards, or customers.

What is shadow AI?

Shadow AI is AI use that happens outside a formal governance process.

It can include:

• Employees using unapproved AI tools

• Business teams adopting AI features without review

• Vendors enabling AI capabilities after onboarding

• AI functionality embedded in existing SaaS platforms

• Internal experiments that move into real workflows

• AI models used without documentation

• AI agents created without review of permissions or oversight

• Public AI tools used with confidential or regulated data

Shadow AI does not always happen because people are reckless. Often, it happens because AI is easy to access, embedded into everyday tools, and changing faster than governance workflows.

Why shadow AI is different in regulated industries

Every organization should care about unmanaged AI. Regulated institutions have more at stake.

Shadow AI can create exposure across:

In regulated financial services, “we did not know this AI was being used” is not a defensible governance position.

Where shadow AI appears

Shadow AI often enters through several paths.

1. Employee productivity tools

Employees may use AI to:

• Summarize documents

• Draft emails or policies

• Analyze spreadsheets

• Prepare customer responses

• Translate content

• Generate meeting notes

• Research regulations

• Build internal templates

Some of these uses may be low risk. Others may involve confidential, customer, or regulated information.

2. Existing SaaS vendors

Vendors increasingly add AI features into tools the organization already uses.

Examples include:

• AI writing assistants

• AI-generated summaries

• Automated classifications

• Predictive recommendations

• AI-powered search

• Customer support copilots

• AI meeting notes

• AI document review

• Workflow automation

The vendor may have been approved before the AI feature existed. That means the original review may no longer reflect the current risk.

3. Business-led AI experiments

Business teams often move quickly when they see a productivity opportunity.

A pilot may begin as a small experiment, then expand into a recurring workflow. A team may test an AI tool with sample data, then start using real business data. A proof of concept may become operational before risk, compliance, security, or legal teams are involved.

4. Vendor AI and third-party model providers

A vendor may use AI behind the scenes, even if the customer-facing product does not look like an AI tool.

That can include:

• Model providers

• AI infrastructure

• AI-powered analytics

• Automated decision support

• AI-assisted human operations

• AI used in support, security, or quality control

If the vendor does not disclose this clearly, the institution may miss the exposure.

5. AI agents and automation workflows

Shadow AI becomes more serious when AI agents are involved.

An AI agent may:

• Access systems

• Retrieve data

• Trigger workflows

• Update records

• Send communications

• Escalate cases

• Interact with other tools

If agent permissions are not documented and governed, the institution may not know what the agent can do or what evidence exists after it acts.

Why annual surveys are not enough

Many organizations start AI discovery with an internal survey.

That is useful, but it is not enough.

Annual or periodic surveys depend on people knowing what counts as AI, remembering what they use, responding accurately, and reporting changes after the survey closes.

That approach breaks down because:

• AI features change frequently

• Employees may not recognize embedded AI

• Vendors may add AI after onboarding

• Use cases evolve

• Teams may underreport informal experimentation

• Ownership changes

• Agents and automations expand

AI discovery needs to run continuously, on the same rhythm as the AI adoption it’s tracking. See Why Spreadsheets Fail for AI Governance for what a continuous system needs to do that a periodic survey or static spreadsheet can’t.

How to find shadow AI

A practical shadow AI discovery process should combine multiple signals.

1. Start with an AI inventory

Create a central inventory for AI systems, vendors, models, agents, and use cases. See How to Build an AI Inventory for the full field list and a risk scoring framework to apply once systems are captured.

The inventory should capture:

• Name of tool, vendor, system, model, or agent

• Business owner

• Purpose

• Data used

• Users or teams

• Customer impact

• Vendor involvement

• Risk tier

• Review status

• Approval history

• Monitoring requirements

• Reassessment triggers

2. Review vendor portfolios

Look at vendors already in use and identify which have added AI features.

Prioritize vendors that touch:

• Customer data

• Financial data

• Lending or servicing workflows

• Customer communications

• Compliance processes

• Fraud or risk workflows

• Employee or applicant data

• Core operational systems

3. Add AI questions to procurement and renewal workflows

New vendor intake and renewals should include AI-specific questions. Our AI vendor due diligence questionnaire has the full set to build into that process:

• Does the vendor use AI?

• Which features use AI?

• Is customer data processed by AI?

• Are third-party model providers involved?

• Are AI features optional or default?

• What changes trigger notice?

• What documentation is available?

4. Create a simple internal AI intake path

Employees need a clear way to disclose or request AI use.

The process should be simple enough that teams actually use it, but structured enough to capture the information risk and compliance teams need.

Ask for:

• What tool or system is being used?

• What business purpose does it serve?

• What data will be used?

• Who will use it?

• Will it affect customers or regulated processes?

• Is a vendor involved?

• Does it take action or only generate outputs?

5. Monitor changes after approval

Discovery should not stop once a use case is approved.

Reassessment should be triggered when:

• AI functionality changes

• A vendor adds AI features

• A model changes

• Data use changes

• Customer impact increases

• System access expands

• Agent permissions change

• A pilot becomes operational

• A regulation or policy changes

What to do once shadow AI is found

Finding shadow AI is only useful if it leads to governance.

When a new AI use is identified, route it through a risk-based process:

1. Add it to the AI inventory.

2. Assign an owner.

3. Classify the use case.

4. Identify data and vendor involvement.

5. Determine customer or regulatory impact.

6. Route to the right reviewers.

7. Document approval, conditions, or rejection.

8. Define monitoring and reassessment requirements.

9. Retain evidence.

Bringing that AI into a governance process that can stand up to review is the point, for the team using the tool as much as for the institution accountable for it.

FAQs

What is shadow AI?

Shadow AI is the use of AI tools, systems, vendors, models, agents, or embedded AI features without formal visibility, review, or approval through an organization’s AI governance process.

Why is shadow AI risky?

Shadow AI is risky because the organization may not know what data AI is using, who owns the use case, whether customers are affected, whether vendors are involved, or what evidence exists to prove oversight.

Where does shadow AI usually come from?

Shadow AI often comes from employee use of public AI tools, AI features embedded in existing SaaS platforms, vendor product updates, business-led experiments, and AI agents or automations created outside formal review.

How can companies find shadow AI?

Companies can find shadow AI by building an AI inventory, adding AI questions to procurement and renewals, reviewing vendor portfolios, creating a simple AI intake process, and monitoring changes after approval.

Are AI inventories enough to manage shadow AI?

An AI inventory is the starting point, but it is not enough by itself. Organizations also need review workflows, risk classification, approvals, monitoring, reassessment, and audit-ready evidence.
