Waterfall Unidirectional Gateways enable the safe replication of industrial systems with over 100 software connectors to choose from. Safe replication is executed in real-time to enterprise networks, where users can interact normally and bi-directionally with replica servers, keeping industrial networks safe from cyber attacks. The connectors are commercial off-the-shelf (COTS) and can run on Waterfall Hosts, customer supplied servers or virtual machines. Waterfall connectors are supported on Windows, Linux, Solaris, AIX, VxWorks and other operating systems.
