genua Dioden (Data Diodes) vs Waterfall Security Solutions: Side-by-Side Comparison (2026)

genua Dioden (Data Diodes): Hardware data diodes enforcing unidirectional data transfer for sensitive networks. built by genua GmbH. Core capabilities include Unidirectional data transfer enforced by hardware (diode function), Security by Design through static diode architecture, Industrial monitoring support (cyber-diode variant)..

Waterfall Security Solutions: Hardware-enforced unidirectional gateways for OT/ICS network security. built by Waterfall Security Solutions. Core capabilities include Unidirectional Security Gateways (hardware-enforced one-way data flow between OT and IT networks), Hardware-enforced OT remote access (HERA) with IT/OT segmentation maintained, Tamper-proof forensic data repository (Waterfall Blackbox)..

Both serve the Operational Technology Network Segmentation market but differ in approach, feature depth, and target audience.
