ABOUT L4 TRAFFIC MONITOR
The Web Security appliance has an integrated Layer-4 Traffic Monitor that detects rogue traffic
across all network ports and stops malware attempts to bypass port 80. Additionally, when
internal clients are infected with malware and attempt to phone-home across non-standard
ports and protocols, the L4 Traffic Monitor prevents phone-home activity from going outside
the corporate network.
