Hi. We recently deployed MS Defender for Endpoint on all our iOS devices through Intune. However, since then, people are complaining their internet browsing experience is not good. It's slow, some sites take forever to load (when they do), etc. When we manually disable the Defender VPN connection, it's working again. How can we fix this issue? Thanks.

@MarkTheITGuy The problem is not with Defender on iOS per se but instead with the ATP module (web content filtering). Microsoft provides a script for that. It can be downloaded here. The problem is, once a policy that contains that script is created in InTune and is applied to iOS devices, traffic becomes very slow and some sites don't even load (bank sites, news sites, etc.). If you let ATP enabled but remove the policy to filter the traffic it will work fine. However, the outbound traffic will not be inspected anymore.

@rickside @MarkTheITGuy , Currently there is a known issue with the content profile (script that you deploy from Intune) which is causing internet connectivity problems. We are looking into this issue. Meanwhile, you can un-deploy this profile to help resolve the internet connectivity problems. Please find more details here.
Also, even without the profile, Defender for Endpoint will still protect you from phishing in real-time leveraging the VPN capabilities. Hope this helps. Please revert back for further questions.

@MWilkins you are absolutely right. On unsupervised devices, the VPN is still present, and it prevents access to random sites (news, banks, etc.). I tried to figure out a way to get rid of the VPN without breaking up Defender status and compliance policy in Intune without any success yet. For the moment, we told our affected users to temporarily disable the VPN when it is not working.
