EAP SSL-TLS Scanning: Category Exclusions and Firewallmanagement not working


I already put those as comments below that article https://community.sophos.com/intercept-x-endpoint/early-access-program/b/blog/posts/https-policy-changes

As I'm unsure, if it's gettig read there, I post it her ein the EAP forums again.

I notice 2 issues so far with the new SSL / TLS Scanning of Intercept-X where it is acting as Man-in-the-Middle SSL Scanner.

1. I cannot manage my comanies Sophos XG and SG firewalls with firefox using windows store certificates (security.enterprise_roots.enabled    true) anymore. Other browsers are working. The firewalls Webadmin is equipped with commercial wildcard certificate for *.owndomain.abc


Excluding owndomain.abc as domain in Sophos Central SSL / TLS Settings is a workaround but we do not want it to be excluded.

When loading the firewall management website with IP the same error appears with firefox.

2. Excluding Banking websites is not working - the Endpoint will still break SSL and re-encrypt the page as can be seen by the issueing CA. That's a no-go.

  • I certainly hope this gets fixed by Sophos soon. Myself and our IT Director are currently in the EAP testing the SSL Decrypt functionality on our workstations and we've been seeing the Firefox error with all of our organization's URLs (we use a wildcard cert.) We've since exempted *.ourdomain.edu and it seems to have taken care of it, with the exception of our firewall's management panel, which we connect to via IP address. As you mentioned, Sophos is not honoring IP address exemptions. Thankfully, with it only being us two using that, and neither of us using Firefox as a primary browser, it's not a big deal for now.

    However, given this plus other issues I'm seeing as suggested topics at the right, this feature still needs a lot of work before it sees general rollout.
