Limit employee use of AI with sensitive information by defining approved tools and permitted data, training staff on clear rules, and enforcing those rules with classification and data loss prevention (DLP) where available. A blanket ban is difficult to enforce, while an enterprise subscription alone does not guarantee that sensitive data is protected.
Start with approved tools and clear data rules
Make an inventory of the AI services employees use, including browser-based sites, installed applications, add-ins, APIs, and AI features built into business software. Treat an unapproved service as an external recipient of any prompt, file, or connected data sent to it.

Publish a short list of approved services and specify which data classes and uses are allowed in each. Give employees a plain-language rule: do not enter, upload, or connect confidential records, personal data, credentials, source code, or other restricted material to an unapproved service. For approved tools, state any limits and when additional review or approval is required. Communicate the policy to everyone involved in using AI.

Classify information and enforce the rules
Use the organization’s data classifications and sensitivity labels as the basis for AI handling rules. Configure DLP to detect sensitive information in prompts and uploads, then choose whether the policy should warn users, block an action, or allow an override under defined conditions.

Controls need to cover the channels employees actually use: browsers, local applications, add-ins, and network paths. Microsoft documents Purview endpoint DLP controls that can warn or block users sharing sensitive information with third-party generative AI sites through a browser, as well as network data security examples. These capabilities depend on configuration, supported platforms, licensing, prerequisites, and rollout status; some documented features may be in preview. Test them in your environment before describing coverage as comprehensive.
Review an AI service before approving sensitive workflows
When a business workflow requires sensitive information, evaluate the specific service and its settings before approving it. Check how prompts and responses are handled, what retention and audit controls are available, whether organizational permissions and sensitivity labels carry through, and what happens to connected data or agent activity.

Do not transfer assurances from one service to another. Microsoft’s documented enterprise data protections refer to Microsoft Copilot and Microsoft Copilot Chat under applicable product terms; they do not establish equivalent protections for every AI tool, plan, or subscription.

Monitor use, then review and improve the policy
Discovery and audit capabilities can help identify unsanctioned use and reveal gaps in policy coverage. Insider-risk monitoring may support an investigation, but monitoring does not replace access controls, DLP, or employee instructions. Limit monitoring to appropriate roles and privacy controls, and define how alerts are reviewed and escalated.

The right safeguards depend on the data, use case, and processing context. The UK Information Commissioner’s Office (ICO) states, “There is no ‘one-size-fits-all’ approach to security,” in its guidance on assessing security and data minimisation in AI. The ICO says this AI guidance is under review following the Data (Use and Access) Act; it is UK-focused guidance, not a substitute for jurisdiction-specific legal advice or an organization’s own compliance assessment.
