Summary:
Microsoft Purview DLP will support Microsoft 365 Copilot to prevent sensitive data leakage by blocking Copilot responses to prompts containing sensitive information. Rolling out from November 2025 (preview) to April 2026 (general availability), admins can configure policies in the Purview portal to safeguard data.
Details:
[Introduction:]
We are expanding Microsoft Purview Data Loss Prevention (DLP) to support Microsoft 365 Copilot, helping organizations safeguard prompts that contain sensitive data. This real-time control helps mitigate data leakage and oversharing risks by preventing Microsoft 365 Copilot-including pre-built agents-from returning a response or using sensitive data for grounding in Microsoft 365 or the web.
This message is associated with Microsoft 365 Roadmap ID 515945.
[When this will happen:]
Public Preview: We will begin rolling out in mid-November 2025 and expect to complete by late December 2025.
General Availability (Worldwide): We will begin rolling out in late March 2026 and expect to complete by late April 2026.
