Waterfall Security Solutions provides hardware-enforced OT (Operational Technology) security products designed to protect industrial control systems and critical infrastructure networks from cyber threats. Their core technology centers on Unidirectional Security Gateways (USGs) — hardware and software combinations that physically enforce one-way data flow between OT and IT networks, making it physically impossible for attacks to traverse from IT/external networks into OT environments. **Product Portfolio:** - **HERA** – A hardware-enforced remote access solution for OT networks, enabling secure connectivity while maintaining IT/OT network segmentation. - **WF-600 / WF-500** – Unidirectional Security Gateway appliance platforms. - **Waterfall for IDS** – Enables safe deployment of intrusion detection systems within OT environments. - **WF-Flip** – Supports scheduled, secure one-way data transfers for software/firmware updates into OT networks. - **WF-Secure Bypass (WF-SBP)** – Provides emergency interactive remote access capability. - **Waterfall Blackbox** – A tamper-proof forensic data repository for OT environments. - **Waterfall Central** – A centralized software platform for monitoring and managing all deployed Waterfall gateways. **Industries Served:** Electric Power, Manufacturing, Water & Wastewater, Metals & Mining, Rail, Oil & Gas, Facilities, Government & Defense. **Use Cases Addressed:** OT network visibility, ransomware protection, IT/OT network segmentation, cloud connectivity for OT data, compliance with OT/industrial security standards, and tamper-proof forensic recordkeeping.
