SNi20: Information in bref

SNi20 overview

Perfectly suited to your operational environment, the SNi20 industrial firewall features seamless and unique network integration (routing and NAT) and advanced security. It provides deep packet inspection (context-based analysis), and thus protects your industrial communication protocols. The firewall guarantees your infrastructure’s operational reliability, delivering optimal business continuity at all times. This is true even in the event of a failure. How? Thanks to its high-availability system and operational network security mode. Choose SNi20, the new industrial firewall dedicated to industrial systems which integrates without modifying the existing operational infrastructure.

By strengthening the security level on control systems and PLCs, and conducting a deep inspection (Stateful DPI) of the traffic on the operational network, it will reduce the risk of corruption for data flow and business application.
