WildFire Real-Time Signature Updates
The Palo Alto Networks next-generation firewall
now supports real-time retrieval of WildFire® signatures.
This enables you to access the signatures as soon as they are generated, which greatly
minimizes the window in which malware can infiltrate your network.
Signature downloads that occur during a sample check are saved in
the firewall cache and are available for fast (local) look-ups.
In addition, to maximize coverage, the firewall automatically downloads
a supplementary signature package on a regular basis when you enable real-time
signatures. These signatures remain available in the firewall cache
until they become stale and are refreshed or are overwritten by
new signature updates. Palo Alto Networks determines which protections
are the most relevant and timely and includes those in the signature
packages.
- To unlock access to real-time WildFire signatures,
you must have a WildFire subscription service license. Make sure
to activate the license on
the firewall if you have not done so already.
- Select .
- Manually upload the license key or retrieve it from the Palo Alto Networks license server.
- Verify that the WildFire subscription license is active.
- Set the schedule for the firewall to retrieve WildFire
signatures in real-time and install periodic signature packages
every five minutes.Even when the firewall is configured to use real-time signatures, supplemental signature packages are still installed on a regular basis. This provides an up-to-date signature source when you experience connectivity issues, as well as a speed benefit, where signatures are available locally.
