Microsoft Purview: Data Security Investigations – analyze files tied to endpoint DLP alerts

Microsoft 365 Message Center Archive by Merill Fernando

Summary

Speed up analysis of exfiltrated content by launching Data Security Investigations (DSI) from endpoint Data Loss Prevention (DLP) alerts. In DSI, define your endpoint DLP query (for example, time range, users, and endpoints). DSI then automatically gathers the related files that triggered the alerts for review (for example, UserA downloaded a file on 3/1/2026).
