DLP for SaaS Apps - Endpoint DLP/MDE + Purview Browser Extension

I need help verifying my understanding of how Purview tools control file upload/download and clipboard copy/paste actions. Here's the situation:

Goal: Block file upload/download, copy/paste of sensitive data to/from SaaS apps.

Deployment: Rolling out MDE (in Passive mode) or Endpoint DLP (Onboarding device to Purview) and the Purview browser extension for Chrome/Firefox.

 

My Understanding:

Copy Control: Handled by Endpoint DLP/MDE on the endpoint.

Upload/Download/Paste Control: Requires the Purview browser extension (or native browser support Edge/Safari).

Specific Question: The browser extension isn't available for macOS. I've read that MDE on macOS can handle everything (file upload/download and clipboard control). Could someone confirm if the table I've created correctly reflects this?

      Hi,

      Just to clarify a few points, as this can be a bit confusing:

      • On macOS, the Endpoint DLP / MDE sensor does not fully enforce paste actions into SaaS applications on its own. Clipboard activity can be monitored at the endpoint, but browser-based paste is not consistently blocked without browser integration.
      • There is currently no native Purview integration for Safari comparable to the native Edge integration on Windows. The “native browser” capabilities are effectively limited to Edge on Windows.
      • Because of this, MDE on macOS does not provide full parity with Windows for SaaS upload, download, and paste controls. You can get partial coverage and visibility, but not end-to-end enforcement for web-based actions.

       

      I also updated the clipboard enforcement summary:

      Hopefully this helps clarify the differences and set expectations correctly. 🙂
