Endpoint DLP
Understanding the Concept
Endpoint DLP extends protection to Windows 10/11 and macOS devices, monitoring activities like copying to USB, printing, uploading to cloud services, and accessing by unallowed apps.
Unlike cloud DLP which protects data in transit, Endpoint DLP protects data at rest on devices. It requires the Microsoft 365 E5 or E5 Compliance license.
Endpoint DLP uses the same unified policy engine, so you can create policies that apply to both cloud services and endpoints. This ensures consistent protection across the data lifecycle.
Key Points
- Windows 10/11: Full support including USB, print, clipboard
- macOS: Supported with some feature differences
- Device Onboarding: Required for endpoint monitoring
- App Restrictions: Block specific apps from accessing files
- USB/Print Control: Block or audit sensitive data output
Endpoint DLP Components
Device Onboarding
Devices enrolled and configured for DLP
File Activity Monitoring
Watches file operations: copy, print, upload
Content Inspection
Files scanned for sensitive content
Policy Evaluation
Activity checked against endpoint DLP policies
Action Enforcement
Block, warn, or audit based on policy
Why This Matters in Real Organizations
Data often leaves the cloud boundary through endpoints: USB drives, printers, and local apps. Without Endpoint DLP, sophisticated DLP elsewhere can be bypassed by downloading and emailing from personal accounts.
