Lion Server Firewall (LSF) v3.2.0 is the host firewall on Lionhost WHM/cPanel servers (and standalone Linux).
It manages iptables and ip6tables (plus ipset when available), is dual-stack IPv4/IPv6, and includes LFD brute-force watching, PSAD port-scan detection, GeoIP, L3/L4 flood limits, ModSecurity escalation, and a WHM plugin with Simulator and Health check.
It is not a copy of CSF. Do not run LSF and CSF on the same server.
