Unable to Restrict Sensitive Data Access by Microsoft Edge via Endpoint DLP Policy

Hello everyone,

 

I've been running into a peculiar issue where actions we have configured to be blocked via our Endpoint DLP policies do not apply to the Microsoft Edge browser. Currently, we have a DLP policy configured to block attempts to access protected files by a list of restricted apps. Our restricted apps include "firefox.exe", "chrome.exe", "msedge.exe" and "msedgewebview2.exe". When the sensitive content is accessed by either Chrome or Firefox, the DLP policy works correctly (Block with override), but the policy completely refuses to work in any scenario that involves Edge. The data we are using as an example is able to be accessed by the Edge executables without restriction.

 

Has anyone else run into this issue? It's strange to me that for some reason Edge is just completely exempt from the DLP policy actions we have implemented.

 

Thank you!

    I'm encountering a similar problem in Edge. Some websites will block a test upload of a file containing test data and generate the justification pop up. But on other sites an upload of the exact same file is allowed through without any prompt.. very inconsistent whereas Chrome works every time with the same set of tests.
