Palo Alto Networks (PAN-DB) URL filtering

URL filtering with PAN-DB can use either the public cloud or a private cloud. If your firewall can directly access the internet the public cloud is the right option. PAN-DB private cloud can be installed on one or more M-500 appliances that serve as an intermediary. New updates are published every 5 to 10 minutes. The rapid updates are to incorporate WildFire data. WildFire requires an additional subscription. Best practice is to update WildFire data every minute.
