Why each option
Palo Alto Networks WildFire rapidly delivers newly discovered threat intelligence from the cloud to subscribed firewalls, enabling near real-time protection against zero-day exploits.
While this might have been an older update interval, it is not the correct, optimized interval for WildFire as of PAN-OS 6.1.
This interval is significantly longer than the rapid updates provided by WildFire as of PAN-OS 6.1.
A daily update interval would be too slow to effectively combat rapidly evolving zero-day threats.
As of PAN-OS version 6.1, WildFire significantly reduced the update interval for new threat signatures and intelligence (generated from previously unknown files analyzed in the cloud) to five minutes. This rapid update cycle ensures that firewalls quickly receive protection against zero-day and advanced persistent threats.
This hourly interval is not the optimized, near real-time update frequency that WildFire provides.
