About Waterfall Security Solutions
At a glance
Waterfall Security Solutions is a cybersecurity company specializing in Cyber-Physical Security, founded in 2007 and headquartered in Rosh Ha'ayin, Israel. It is privately held.
Waterfall Security Solutions is an industrial cybersecurity company founded in 2007 that specializes in hardware-enforced security for operational technology (OT) networks. The company's core technology is based on Unidirectional Security Gateways (USGs), which are hardware and software combinations that physically enforce one-way data flow to prevent cyber threats from reaching critical industrial networks. Their product portfolio includes several platforms: HERA, a hardware-enforced remote access solution for OT environments; WF-600 and WF-500 unidirectional gateway appliances; Waterfall for IDS, which enables safe deployment of intrusion detection systems in OT networks; WF-Flip for scheduled secure updates; WF-Secure Bypass for emergency interactive remote access; and Waterfall Blackbox, a tamper-proof forensic data repository. The Waterfall Central software platform allows centralized management and monitoring of deployed gateways. The company targets critical infrastructure sectors including electric power, oil and gas, water and wastewater, manufacturing, rail, metals and mining, facilities management, and government and defense. Their solutions address use cases such as IT/OT network segmentation, ransomware protection, OT visibility, cloud connectivity for OT data, regulatory compliance with industrial security standards, and tamper-proof forensic record-keeping. Waterfall's approach centers on physical unidirectionality enforced at the hardware level, which the company positions as providing stronger protection than software-based firewalls for critical OT environments. The company operates globally and maintains a partner program for system integrators and resellers serving industrial enterprises.
