What is shadow AI?

Shadow AI is unsanctioned AI: tools the business hasn't approved, used for work the business is responsible for. IBM defines it as the unsanctioned use of any AI tool or application by employees or end users without formal approval or oversight from IT. It is a subset of shadow IT, with AI-specific risks: these tools read whatever you give them, may retain it depending on the plan, and return confident output that can be wrong.

Shadow AI is rarely malicious. People use the tools that help them finish the job, and if the company hasn't provided one, they bring their own.

Shadow AI by the numbers

In Microsoft and LinkedIn's 2024 Work Trend Index, a survey of 31,000 people in 31 countries, 75% of knowledge workers said they use AI at work, and 78% of AI users said they bring their own AI tools to work.

The cost shows up in breaches. IBM's Cost of a Data Breach Report 2025 found that one in five organizations reported a breach due to shadow AI, and that organizations with high levels of shadow AI faced an average of $670,000 in higher breach costs than those with low or no shadow AI. Only 37% had policies to manage AI or detect shadow AI.

Shadow AI examples in a lean company

None of these feel risky to the person doing them.

Personal chatbot accounts

A sales rep pastes a customer list into a free consumer AI account to draft outreach. The data now sits outside company control, under consumer terms.

Unvetted meeting note-takers

An AI note-taking bot joins client calls from one employee's calendar and stores recordings with a vendor nobody has reviewed.

Browser extensions

An AI writing extension can read the pages a user opens, including the CRM and email.

AI features switched on by default

Software you already pay for adds AI features that process your data, and nobody decides whether to use them.

Shadow AI vs shadow IT vs sanctioned AI

	Shadow IT	Shadow AI	Sanctioned AI
What it is	Any unapproved software, hardware or cloud service	Unapproved AI tools, accounts or features	AI tools the company has approved and configured
Main risk	Unpatched systems and data in unknown places	Sensitive data in prompts, data retention, unchecked output	Misuse inside approved tools
Visibility	Partial, through network and expense data	Low; often a browser tab or a personal account	Admin consoles, logs and usage reports
Typical fix	An approved software catalog	Approved AI tools, data rules and training	Ongoing governance and review

How to reduce shadow AI without banning AI

Bans tend to push AI use further out of sight. These steps bring it into the open.

Publish a short list of approved tools on business plans, with data rules for each
Configure approved tools so people want to use them, with shared projects and prompts
Define what never goes into any AI tool, such as credentials or customer financial data
Review AI features in software you already use and switch off what you haven't approved
Train everyone on safe use and require human review of customer-facing output

How Operator Intelligence helps teams handle shadow AI

Operator Intelligence treats shadow AI as a sign of unmet demand, not only a compliance problem. Our AI governance work gives $1M–$10M companies right-sized rules: an acceptable use policy, an approved-tool list, data rules and review steps. The free AI acceptable use policy template is a good starting point.

The other half is giving people something better than their personal accounts. Our AI workspace setup configures approved tools, such as Claude Projects, custom GPTs or Gemini Gems, in the team's own business accounts, and training builds the AI literacy people need to use them safely. Where output carries risk, human-in-the-loop review keeps a person accountable.

Shadow AI FAQ

Is using ChatGPT at work shadow AI?

Only if the company hasn't approved it for that use. The same tool can be sanctioned on a business plan with admin controls and be shadow AI on an employee's personal account.

Should we ban AI tools to stop shadow AI?

Bans rarely hold, because people keep using tools that help them. Approve tools on business plans, set clear data rules, train the team and check periodically for unapproved use.

How do we find the shadow AI we already have?

Start by asking: an anonymous survey of the tools people use, followed by a review of expense reports, browser extensions and AI features in existing software. Larger companies can add SaaS discovery tools.

Does shadow AI create legal risk?

It can, for example when client data goes to a tool under terms you never agreed to. Obligations depend on your industry, contracts and jurisdictions, so work with counsel for legal obligations. Law firms carry specific confidentiality duties; see AI for law firms.

Bring AI use into the open

We'll help you replace shadow AI with approved, configured tools and rules your team will actually follow. Or start with the AI readiness assessment.
