Testing of web content filtering policy from M365 Defender

VinodS2020 

Hello,
I have recreated the environment in the dev environment. Finally, WCF is working as expected. Please find the summarization below:

1. Users and Admin must have appropriate MDE licenses. (MDE 2 in my case)
2. Device group must be created with role assignment. (create an Entra ID security group and then create a role under settings> endpoint> permissions> roles. Post that create the group and apply changes) 
3. Cloud and network protection must be enabled on end-user devices.
4. WCF must be enabled from settings> endpoint> advanced features (security.microsoft.com)
5. Re-create the WCF policy, this time your device group will be visible for assignment.

Please let me know if you have any questions.

Thanks
