🚨 The Signal: Purview Exact Data Match (EDM) now offers a 'unique row' counting mode, improving data loss prevention (DLP) accuracy by preventing over-counting of sensitive information within a single record. This enhances data protection and compliance.

The Impact

Security and compliance teams are affected, gaining improved accuracy in DLP policy enforcement and reporting.

  • Security Teams: Improved accuracy in DLP policy enforcement.
  • Compliance Teams: Better reporting on sensitive data matches.
  • Data Owners: More reliable protection of sensitive information.

The Action

  3. Test policy changes in a non-production environment.
  4. Update relevant DLP policies in the Microsoft Purview compliance portal (https://compliance.microsoft.com/dlp/policies).
