I just read this article: https://borncity.com/win/2022/11/15/windows-server-2012-r2-sophos-user-authentication-using-heartbeat-disabled-on-rds-servers/
saying a customer found out tha his Windows 2012 R2 Servers no longer send their heartbeat status to the XG/S Firewall after Sophos disabled that feature.
Can Sophos confirm that is true?
I cannot report this from our side - our 2012 R2 machines have heartbeat - but the reason may be that the relevant updates have not yet been pushed by central in our region.
Looking forward to your answers on that thing.
I want to add: the blog post is a bit mixed up - writing of SATC, User authentication and heartbeat things. SATC has been replaced by Intercept-X - I know.
Allow us some time to inquire with our product teams to clarify this for you.
