Unidirectional Security Gateways

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 hardware components – transmitter, fiber optic cable and receiver, (or core data diode technology) – along with the software components – application software connectors – ensure one-way transmission and replication of server information from an industrial control network to an external network, but prevent the propagation of any virus, DOS attack, human error or any cyber attack at all back into the protected network.
