Waterfall Unidirectional Security Gateways enable safe IT/OT integration. The gateways replace firewalls in industrial network environments, providing absolute protection to control systems and operations networks from attacks originating on external networks. The Gateways enable vendor monitoring, industrial cloud services, and visibility into operations for modern enterprises and customers. Unidirectional Gateways replicate servers, emulate industrial devices and translate industrial data to cloud formats. As a result, Unidirectional Gateway technology represents a plug-and-play replacement for firewalls, without the vulnerabilities and maintenance issues that always accompany firewall deployments.
Unidirectional Gateways contain both hardware and software components. The hardware components include a TX Module, containing a fiber-optic transmitter/ laser, and an RX Module, containing an optical receiver, but no laser. The gateway hardware can transmit information from a signaling system network to an external network, but is physically incapable of propagating any virus, DOS attack, human error or any cyber attack at all back into the protected network.
