Summary

Microsoft Purview Data Loss Prevention (DLP) is expanding to Microsoft Cowork, enabling data security admins to use a single policy across Microsoft 365 Copilot and Cowork. The integration helps protect sensitive AI interactions by preventing the use of labeled knowledge sources, blocking prompts that contain supported sensitive information types, and restricting sensitive prompts from being sent to Bing for web search.
