Waterfall Unidirectional Security Gateways

Waterfall Unidirectional Security Gateways enable safe IT/OT integration, secure remote access, and real-time industrial network monitoring. The gateways replace one layer of firewalls in an industrial network environment, providing industrial control systems with protection from targeted attacks, secure enterprise-wide visibility and safe remote access.


Unidirectional Security Gateways, from Waterfall Security Solutions are a combination of hardware and software, offering protection with network visibility. The hardware transmits information from industrial and control networks to external networks but is physically incapable of propagating any online cyber attack back into the protected network. The software connectors replicate servers and emulate devices, enabling enterprise users and applications to continue accessing OT data bidirectionally from the replica servers – all data that is allowed to be shared with the enterprise is available in the replicas. The software connectors duplicate servers and simulate devices, allowing enterprise users and applications to maintain bidirectional access to OT data from the replicated servers. All data permitted for sharing with the enterprise is accessible within the replicas.
