Worth mentioning these on the Qubes-Whonix security page for advanced users?
1. Suricata
Looks like it replaces the sys-firewall
and does packet inspection (IDS, IPS) to look for malicious traffic. Larger project has been around since 2009.

Suricata is an open-source detection engine that can act as an intrusion detection system (IDS) and an intrusion prevention system (IPS). It was developed by the Open Information Security Foundation (OSIF) and is a free tool used by enterprises, small and large. The system uses a rule set and signature language to detect and prevent threats. Suricata can run on Windows, Mac, Unix and Linux.
As discussed in the previous articles, intrusion detection “detects” and “alerts” a threat. In contrast, an intrusion prevention system also takes action on the event and attempts to block the traffic. Suricata can do both and also does well with deep packet inspection. Making it perfect for pretty much any kind of standard security monitoring initiatives your company might have.
