Microsoft Purview compliance portal: Endpoint Data Loss Prevention - Optical Character Recognition (OCR) on Mac Endpoints

🚨 The Signal: Microsoft Purview DLP on Mac endpoints now uses Optical Character Recognition (OCR) to scan images for sensitive content. This enhances data protection by preventing sensitive information in images from exfiltrating, aligning Mac endpoint security with other platforms.

The Impact

Security teams and Mac users are affected, reducing the risk of sensitive data exposure via images.

• Security Teams: Reduced risk of data exfiltration from Mac endpoints.
• Mac Users: Enhanced protection against accidental sharing of sensitive image content.
• Compliance Officers: Improved adherence to data protection regulations and policies.
• Incident Responders: Fewer incidents related to image-based data loss.

The Action

1. Review existing Purview DLP policies targeting Mac endpoints to ensure they cover image content.
2. Verify that OCR scanning is enabled for relevant DLP rules within the Microsoft Purview compliance portal.
3. Communicate enhanced image protection capabilities to Mac users and relevant stakeholders.
4. Monitor DLP alerts for image-based sensitive content detections on Mac endpoints.
