Waterfall Security Solutions manufactures unidirectional gateways, hardware that allows data to flow out of an industrial network while making inbound connections physically impossible. The products replicate historians, OPC servers and other data sources to the IT side so that business users see live data without access to control systems. Customers include nuclear and conventional power plants, rail operators, water utilities and refineries, and the company publishes an annual report on OT incidents.
