Microsoft Defender Implementation Issue.

Question

Hello,

We are trying to use Microsoft Defender Antivirus for our production workstations. As per Microsoft documentation, we have enabled certain settings to use Defender to block specific content on user endpoints. However, we have observed that Defender only blocks content in Microsoft Edge, but not in Chrome, Brave, or other third-party browsers.

We have enabled Network Protection in the Defender Baseline, as suggested in the documentation, to apply web filtering in Chrome and Firefox, but this has not resolved the issue.

Currently, we are using GravityZone Bitdefender, which works well in our environment. However, we are looking to switch to Microsoft Defender because we have Business Premium Licenses, which include Defender for Antivirus.

Could someone assist with fixing this issue? Any suggestions or documentation references on how to implement this effectively would be greatly appreciated.
