Palo Alto HA ( High Availability )

*Palo Alto HA (High Availability)* is a feature that provides redundancy and ensures network availability by configuring two or more Palo Alto firewalls in an active/passive or active/active setup. In **active/passive mode**, one firewall is active while the other is on standby, taking over in case of failure. In **active/active mode**, both firewalls are active and share the traffic load. HA ensures seamless failover, synchronized configurations, and stateful session recovery to maintain continuous network security.
