Key Benefits

detailed Features

High Performance and Flexible Network Connectivity

Deploy next-generation firewalls purpose-built for mid-sized and distributed enterprises, delivering high-performance, multi-gigabit threat prevention while supporting high port density, including 10 GbE ports, for flexible and scalable network connectivity. 

Blocks More Attacks With RTDMI™

Real-Time Deep Memory Inspection (RTDMI™) proactively detects and blocks unknown malware via deep memory inspection in real time, a revolutionary approach to defend against zero-day and side-channel attacks and other unrecognized threats. 

Low Total Cost of Ownership

Simplified Centralized Management

Increase efficiencies in deploying and managing distributed firewalls via configuration administration enhancements and bulk deployment capabilities included in all licensing tiers.
