A WildFire appliance cluster is an interconnected group of WildFire appliances that pool resources to increase sample analysis and storage capacity, support larger groups of firewalls, and simplify configuration and management of multiple WildFire appliances. This is especially useful in environments where access to the WildFire public cloud is not permitted. You can configure and manage up to twenty WildFire appliances as a WildFire appliance cluster on a single network. Clusters also provide a single signature package that the cluster distributes to all connected firewalls, high-availability (HA) architecture for fault tolerance, and the ability to manage clusters centrally using Panorama. You can also manage standalone WildFire appliances using Panorama.

To create WildFire appliance clusters, all of the WildFire appliances that you want to place in a cluster must run PAN-OS 8.0.1 or later. When you use Panorama to manage WildFire appliance clusters, Panorama also must run PAN-OS 8.0.1 or later. You do not need a separate license to create and manage WildFire appliance clusters.
