Microsoft Purview: Data Loss Prevention for Microsoft 365 Copilot to safeguard prompts

Microsoft 365 Message Center Archive by Merill Fernando
Microsoft 365 roadmap entry

Summary

We are expanding Microsoft Purview Data Loss Prevention for Microsoft 365 Copilot to safeguard prompts containing sensitive data. This real-time control helps organizations mitigate data leakage and oversharing risks by preventing Microsoft 365 Copilot, including pre-built agents in Microsoft 365 Copilot, from returning a response when prompts contain sensitive data or using that sensitive data for grounding in Microsoft 365 or the web.
