Data Loss Prevention Moves to Microsoft Purview: What Changes for MDA Customers

Microsoft is moving file-based data protection from Microsoft Defender for Cloud Apps to Microsoft Purview. The affected file policies need to be recreated as Purview DLP or auto-labeling policies.

What is changing

  • Consolidation: File-based protection rules will be implemented through Microsoft Purview DLP or auto-labeling.
  • Retirement date: Microsoft states that file policies in Defender for Cloud Apps retire on January 6, 2027.
  • One rule set instead of two: Instead of maintaining policies in two tools, classification, protective measures, and reporting will come together in Purview.

Why this is becoming urgent now

Companies with file policies in Defender for Cloud Apps should recreate them as Purview DLP or auto-labeling policies well before the retirement date – including a check that all previous protective measures and exceptions are mapped correctly there.
