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.
