Microsoft Purview: Data Loss Prevention for Microsoft 365 Copilot to safeguard prompts Beta
Data as of 2 hours ago (26 October 2026)
Description
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.
