we're testing Sophis Intercept X Advanced. Unfortunately there seems to be an issue with Sophos and Mozilla Firefox.
But first of all the prerequisites:
My default browser is Firefox. Usually I search by entering keywords in the combined URL/search bar. Since Intercept X is installed after a couple of search requests (or after a couple of minutes; not sure if it's a matter of time or of requests) google.com doesn't load any more, if I search for a keyword. Further, links on google.com don't work any more. Though if I enter a valid URL (including google.com) the website gets loaded as usual. If I restart Firefox everything including search/google works fine again for another couple of minutes. If I deactivate "Schutz vor Netzwerkbedrohungen" (probably "protection against network threats" in English) in the endpoint settings, everything works fine. This and the fact that we didn't have any issues without Intercept X installed make me believe that Sophos is the reason for the above-mentioned behaviour.
That's why I have two questions:
Please let me know if you need any further information. And please don't start a discussion about our default browser. That's not part of this thread :-)
"Block access to malicious website" OFF -> Firefox works perfect...
We created a ticket
Anyone have a solution for this problem? Still having problems with Firefox when "Network Threat Protection" is enabled.
There's an early access version. After we installed this version the problem didn't occurr again. Not sure, if that's the solution for everyone but it's probably worth a try. Since it's early access I recommend to test this version a lot before installing it on all endpoints.
For further information please see here: docs.sophos.com/.../index.html
Thanks for your advice but we already tested the EAP version. problem still exists.
