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
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.
