When can we expect a new version for Big Sur?

I, like many other it seems, have been having problems with our Intercept X and MacOS Big Sur. 

While version 10.0.4 seems to be a bit better than previous releases, we are seeing extremely high CPU usage for com.sophos.endpoint.scanextension on Big Sur when the users are opening large files or compiling code. So much so that users are reporting a notable degradation of performance to the point we have to turn off a lot of Threat Protection features. This has undermined Sophos within the user base so now every problem is getting blamed on host protection! 

I know there are lots of posts around this topic with either scanextension or networkextension and I know Big Sur changed how kernel extensions work etc etc, but I wanted to know if Sophos have acknowledged that this issue will be fixed in future releases and when we can expect a version that plays nicely with Big Sur?

  • That is a path I am exploring but I also am conflicted on the idea of continuing to give $$ to a company that offers such mediocre support for paying customers. I get the commenters who say "maybe don't update as soon as it comes out..." but realistically, we're closer to the next release [of MacOS] than the current version's release and the current isn't working.

  • Hi Everyone, 

    The release of the new version of the Mac Endpoint would be complete in the first week of August. 

    Thanks,

  • We waited to update until Sophos "supported" Big Sur, and that did not end well for us. 

    Annoyingly we don't use Jamf for Mac management but I've heard Bitdefender works quite well so might look at running a POC with that if we're not 100% with the next Sophos release. 

    Absolutely going to block the next MacOS release and watch these forums like a hawk

  • On the topic of Big Sur updates, we have found 11.5 update seems to also improve performance a little. 

  • I hope that will improve the performance, because our Big Sur users are complaining randomly about very slow systems and freezes with Sophos Endpoint, which makes it very hard to analyze and replicate. From my experience the high load is caused by the extensions. Disabling some functions is not a good option, because that´s what we are paying for. On the other hand I have not found any documentation which configuration in Sophos Central is linked to which service on the client. If the problems persist or we have to wait again many months until support for a new OS, I will be forced to look for another software to protect our clients.

  • We started to promote Big Sur update 2 weeks ago but had to withdraw it because of performance issues with Sophos. Users are complaining that everything is slow since they upgraded to BS. Our teams are mainly developers, and they say that their build time increased dramatically. Even on my own machine (on which I use only web browsers) I experienced com.sophos.endpoint.networkextension running at 100% CPU with fans spinning fast. It was even cutting my internet connection. We use Sophos Central with Sophos Endpoint 10.1.4.

  • Hi Glenn,

    Is a fix still on the roadmap? Users are complaining when e.g. node / npm / yarn is touching a lot of files at the same time. The com.sophos.endpoint.scanextension the is using over 300% CPU.

  • It's a good question that deserves a good answer. 

    Is this issue still being worked on internally?
