WildFire inline ML prevents malicious content in real-time using machine learning on the firewall.
To enable your WildFire inline ML configuration, attach the Antivirus profile configured with the inline ML settings to a security policy rule (see Set Up Antivirus, Anti-Spyware, and Vulnerability Protection).
WildFire inline ML is not currently supported on the VM-50 or VM50L virtual appliance.
