RM561892 - Microsoft Purview: Data Loss Prevention for Microsoft 365 Copilot to safeguard prompts for government clouds

Microsoft 365 Roadmap

Summary

We are expanding Microsoft Purview DLP 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 and agents from returning a response when prompts contain sensitive data or using that sensitive data for grounding in Microsoft 365 or the web. This capability currently extends to Microsoft 365 Copilot and agents built in Copilot Studio that are published to Microsoft 365 Copilot.
