Unidirectional security gateway for connected industry

Cyber Security with a4GATE

a4GATE is a unique and secure solution for controlling LAN Ethernet traffic at ISO / OSI Layers 1. The technology allows network designers and architects to build super-secure networks by providing total hardware isolation and segmantation.

The project led to the selection of a hardware component developed in the context of monitoring military installations or power distribution, which require a high level of security, made by the Israeli Terafence Ltd


a4GATE guarantees the highest level of security. Three independent companies, experts in cyber security, have conducted their own penetration tests certifying the level of security.
