If WildFire determines a file is malicious, it generates a new signature in as little as 5 minutes and pushes it to all firewalls globally. Some advanced implementations allow for "inline" blocking of files until the WildFire result is returned, but the fundamental configuration step for all zero-day protection is the forwarding of unknown content to the threat intelligence cloud.
