Updated August 12, 2026: We have decided not to move forward with this change at this time. We will communicate via Message center when we are ready to proceed. We apologize for any inconvenience.
What and why
We are improving transparency in Microsoft Purview Data Loss Prevention (DLP) for managed apps in Microsoft Edge for Business.
The protection that blocks browser developer tools (debug tools) is always enforced by default for managed app scenarios. With this update, administrators will now see this protection explicitly displayed within applicable DLP rules in addition to it being applied behind the scenes.
This change improves visibility and helps admins better understand how managed app protections are configured without changing existing enforcement behavior. It makes protection settings easier to review and validate.
Rollout schedule
- Worldwide: We will communicate via Message center when we are ready to proceed.
