Sophos Endpoint Intercept X (Malicious Traffic Detection) slows down MacOS Monterey extremely

Sophos User5167

Hi all,

following issue: I upgraded different machines (4 for testing) to MacOS Monterey 12.0.1.

They got all the same issue: After upgrading and rebooting, the machines slowing down extremly.

The OS would hang with beach ball and take forever to do even one click. They got useless!

After some testing i found out, if i turned off "Malicious Traffic Detection" in the Runtime Protection Settings of the Endpoint software (10.2.2), the machine starts to work normal, the system brakes and beachballs are gone.

But after i turned "Malicious Traffic Detection" on again and restarted the machine, it slows down again the machines extremely direct after booting.

I can reproduce this setting on all machines with Monterey 12.0.1

Even the latest EAP version of Sophos Endpoint (10.3.0) didn’t fixed this issue.

Any recommendations for this?

    Hello,

    Thank you for reaching out to the Sophos Community Forum.

    Do you know if multiple network extensions are installed on the macOS devices in question? In some cases, having other network extensions installed prior to that of Sophos' can cause issues. 

    I have reached out to you via PM to request logging information from one of the affected devices to look into the issue further.
