What is actually happening
Examples can include summarizing a vendor contract in a consumer chatbot, drafting support responses in an unevaluated browser extension, or using a coding assistant against a repository whose data terms were never reviewed. The governance question is not only who broke a rule; it is which task lacked an approved path and which data or action made the workaround risky.
The risks depend on the provider terms and the use: data may be retained, reused, or processed in an unapproved region; outputs may reach customer-facing work without review; and the organization may have no record of the prompt, response, or downstream action. If the use is absent from the inventory, those questions cannot be answered from the governance record.
Why a ban is not the whole control
A prohibition can stop some uses and is appropriate for some data. It does not by itself create an approved way to complete the underlying task. Without one, activity may move to personal accounts or devices where the organization has less visibility and weaker records. That displacement risk should be measured rather than assumed away.
There is also an adoption cost. If the approved process makes a common task materially slower, the policy has created an incentive to avoid it. That does not excuse unsafe use; it tells the control owner where usability and governance have to be designed together.
When the unsanctioned path is materially easier, circumvention risk rises. Treat friction as a control variable, not as proof of bad intent.
What works
Find out what is actually in use
Start with an inventory process designed with legal, privacy, security, and employee-relations input. Ask which tools and tasks are in use, why the approved path did not fit, and what data or actions are involved. Technical and financial signals can supplement voluntary reporting only when collection, notice, access, and retention are authorized and transparent.
Provide a fast sanctioned path
Prioritize the common, legitimate tasks in the inventory and provide an approved tool or workflow with clear access and a defined request path. The sanctioned option has to meet the task well enough that compliance is practical, while still enforcing the data and action boundaries the use requires.
Classify data, not tools
A tool allowlist is easier to apply when it sits under a durable data-classification rule: which categories of data may enter which classes of system, for which uses, with which review. The tool list can then change without forcing the organization to reinvent the underlying decision each time.
Log the sanctioned path
An approved path can produce a governed record: what system was used, what data class was involved, what output was produced, what review occurred, and what downstream action followed. Logging should be proportionate, disclosed, access-controlled, and retained for a defined period. It supports incident review; it is not permission for indiscriminate surveillance.
The governance framing
Shadow AI sits inside a broader cross-functional responsibility question. Security, legal, IT, data, and business teams may each carry part of the risk while responsibility for the complete user path remains unassigned. Name the decision owner, escalation path, service level for new-tool requests, and evidence reviewed at each renewal. Otherwise the inventory records a symptom without assigning the response.
