To enable hold mode for WildFire real-time signature lookups, you must have
either a WildFire or Advanced WildFire subscription service license. Make sure
to
activate the license on the firewall
if you have not done so already. To verify subscriptions for which you have
currently-active licenses, select and verify that the appropriate licenses display and are not
expired. The example below shows the description for the standard WildFire
license.
