We've been experiencing the same thing. Since MS Defender was deployed to iOS Devices via Intune, the devices connection becomes almost unusable.

As soon as the app is removed, the connection returns to normal and device is usable again.

Hopefully a fix can be found soon.

Hi, MarkTheITGuy ,

Apologies for the inconvenience. This is not an expected behaviour, and we will like to investigate this issue further. It will be helpful if you can send us an in-app feedback using the steps outlined here along with Diagnostics Data enabled to allow us to identify the issue better: https://docs.microsoft.com/en-us/microsoft-365/security/defender-endpoint/ios-troubleshoot?view=o365-worldwide#send-in-app-feedback

Please do mention the issues you are facing in the feedback such as network latencies, or if any particular set of apps is being affected by Defender.

Thanks,

Thanks, Akash.
I've sent a couple of feedback requests. I needed to reinstall the app and sent another feedback request.

As mentioned in the tickets. When the app is installed and enabled, we get many connection timeouts on a host of different sites using different browsers.

I would say on average, 8/10 URLs visited, throw a connection error and time out.

Thanks again for your reply.
