Microsoft Purview: Data Loss Prevention– Enhanced content extraction and file type coverage for DLP on Mac devices
With this release, the file type coverage to scan, classify and protect sensitive content on Mac devices with Microsoft Purview Data Loss Prevention policies will increase from current ~40 file types to 100+ file types. This release will make the coverage of file types on endpoint consistent with other locations such as Exchange, SharePoint and OneDrive. This will also include other enhancements like detecting label from pfile, detecting sensitive content in metadata, and detecting sensitive content in PDF forms.

RyanTech Analysis
This update addresses a critical gap in enterprise DLP coverage. Currently, Mac endpoints have significantly weaker content inspection capabilities compared to Windows devices and cloud locations, creating compliance blind spots in BYOD and creative environments where Macs are prevalent.
Key improvements: The expansion to 100+ file types brings Mac DLP coverage to parity with other Microsoft 365 locations, while enhanced PDF form scanning and metadata detection will catch sensitive data previously missed. The pfile label detection is particularly valuable for organizations using Azure Information Protection extensively.
IT Action Items: With an April 2026 timeline, start auditing your current Mac fleet's file types and DLP policy effectiveness. Test the enhanced detection capabilities in pilot groups, especially in departments heavy on design files, scientific data, or complex PDFs. Update your DLP policies to leverage the expanded file type coverage without overwhelming users with false positives.
