A product adapted to your environment

By combining a unique and a transparent network integration (routing and NAT), with advanced security features, the integration of the industrial firewall SNi20 is made without modifying the existing operational infrastructure.

The guarantee of an operational safety

The SNi20 industrial firewall provides your infrastructure with operational safety through its bypass function, fail safe mode and redundant power supply. All these elements guarantee connectivity even in the event of a hardware or software firewall failure, ensuring high availability of the operational network and continuity of service.

The protection of industrial communication protocols

The SNi20 industrial firewall performs Deep Packet Inspection (DPI) on industrial protocols such as Modbus, UMAS, S7 200-300-400, EtherNet/IP, CIP, OPC UA, OPC (DA/HDA/AE), BACnet/IP, PROFINET, IEC 60870-5-104, IEC 61850 (MMS, Goose and SV) and IT. This contextual analysis of packets (Stateful DPI) of the traffic on the operational network, it reduces the risk of corruption for data flow and business application and also reinforces the security level of the infrastructure.
