Palo Alto Networks Advanced WildFire is a new cloud-based subscription service that detects and prevents modern evasive malware from entering your network by leveraging a new advanced analysis engine. Advanced WildFire is built on an extensible cloud architecture that operates in the WildFire global cloud to stealthily observe malware and apply the latest deep learning-derived analysis techniques, such as intelligent run-time memory analysis, dependency emulation, malware family fingerprinting, malware configuration file analysis, and more, to uncover and determine the true nature of a sample as it passes through your network. Observed malware threats generate WildFire signatures to identify and protect against future infections.

You can now configure the firewall to hold packets for unknown files when performing WildFire real time signature lookups to prevent the first transfer of known malware.
