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.
