Using Microsoft Defender for Cloud Apps to block apps on managed devices.
Greetings, I have been tasked to work with Microsoft Defender for cloud apps and to block the usage of the Firefox browser on all endpoints within my estate apart from a few users who require it. I have tried to unsanctioned app feature. This only displays a warning prompt but users can still proceed with using and interacting with the application. We have already configured web content filtering and works fine. I already looked up other articles relating to downloading a block script but that applies to other security appliances such as firewalls which we don't want to get into. Is there a convenient way to block certain apps usage by solely using Microsoft Defender for Cloud Apps or is this platform only used for monitoring purposes and cannot really block the app by unsanctioning it?
