XDR Allow-Listing signed processes

We have internally developed scripts that we would like to create XDR exclusions or alert level reduction for based on if they contain code signing certificates.

Stale SIP Sessions

Hello all, We seem to have an issue with sip sessions being stuck in the session monitor for weeks and sometimes months. There have been instances, albeit extremely rare, where it prevented new sessions from being formed on a sip trunk we were testing (it's being moved off of the firewall for production).
