Monitor file uploads for copilot.microsoft.com in Edge

Products

• Data Loss Prevention Core Package

Issue/Introduction

Using the out of the box DLP Edge browser extension, DLP does not block or generate incidents when uploading files to 'copilot.microsoft.com'.

Checking the extensions in the browser, we see that the 'Symantec Extension' is listed and enabled. However, when we check the extensions while connected to copilot.microsoft.com, the extension is greyed out. 

Environment

Symantec Data Loss Prevention Endpoint Detection
Microsoft Edge Web Browser

Cause

Working as designed. Microsoft does not allow third party extensions in Edge for 'copilot.microsoft.com'

Resolution

Enable the Content Analysis (SDK plugin) for Edge
