Snort and Suricata are open-source intrusion prevention
system (IPS) tools that use uniquely formatted rules to detect threats. The
IPS Signature Converter plugin enables you to leverage these rules
for immediate threat protection by translating them into
custom Palo Alto Networks threat
signatures. You can then register the custom signatures on
Palo Alto Networks firewalls in specified device groups and enforce
policy using Vulnerability Protection and Anti-Spyware
Security Profiles.
