Microsoft 365 compliance center: Microsoft Purview | Data Loss Prevention – Document Fingerprinting support for additional workloads
Document Fingerprinting in Microsoft Purview Data Loss Prevention (DLP) converts a standard form into a sensitive information type (SIT), which you can use in the rules of your DLP policies. This update extends support for Fingerprint-based SITs to additional workloads, including SharePoint, OneDrive, Teams, and Endpoint and enables admins to adjust threshold while creating Fingerprint SITs.
