What Waterfall Security Solutions Ltd. does
Waterfall Security Solutions Ltd. is an Israel-headquartered, privately held industrial cybersecurity vendor founded in 2007, specializing in hardware-enforced unidirectional security gateways for operational technology (OT) and critical infrastructure environments. Its core product architecture combines proprietary fiber-optic hardware that physically enforces one-way data flow with software connectors and management tools, preventing any network-based cyberattack — including zero-days and nation-state-grade threats — from crossing from IT networks into protected OT networks. The portfolio spans the Unidirectional Security Gateway family (WF-500, WF-600 Performance, and the June 2026 entry-level DiodeCore), hardware-enforced remote access (HERA, WF-Flip, WF-Secure Bypass, WF-RSV), and supporting modules (Waterfall Central monitoring, Waterfall for IDS, Waterfall Blackbox forensic repository), protected by 14 U.S. and 13 Israeli patents and certified to Common Criteria EAL 4+, ANSSI CSPN, NITES, KC, and Israel NISA standards.
The company sells almost exclusively to large enterprise operators of critical infrastructure — electric power utilities, oil and gas operators, rail and metro systems, water/wastewater utilities, manufacturers, data centers, airports, healthcare/biotech firms, and government/defense facilities — through a global direct field-sales motion with dedicated North America and EMEA/APAC teams, complemented by a partner ecosystem of 15+ tier-one industrial OEMs and IT security platforms (Schneider Electric, Siemens Energy, GE Vernova, Alstom, Splunk, AVEVA, Dragos, Fortinet, CyberArk, Emerson, Yokogawa). Revenue is generated through hardware appliance sales, recurring software subscriptions, and professional services under quote-based annual contracts; pricing is not publicly disclosed. Waterfall reports over 1,000 sites protected across more than 20 verticals and operates regional offices in the U.S., Netherlands, Australia, UAE, and Singapore in addition to its Rosh Ha'ayin global headquarters.

Waterfall Security Solutions Ltd. product offering
Product offeringCore offering
Waterfall Security Solutions designs, manufactures, and sells hardware-enforced Unidirectional Security Gateways and related modules for protecting operational technology (OT) networks at industrial critical infrastructure sites. Its proprietary fiber optic hardware physically enforces one-way data flow, preventing any cyber attack from entering protected OT networks while replicating industrial data outward to enterprise, cloud, and analytics systems. The portfolio includes Unidirectional Gateways (WF-500 and WF-600 Performance series), the DiodeCore entry-level gateway, HERA hardware-enforced remote access, Waterfall Central monitoring, and ancillary modules for scheduled updates, emergency access, remote screen view, IDS deployment, and tamper-proof forensic storage.
Product overview
Waterfall Security Solutions offers a hardware-enforced OT security platform centered on unidirectional gateway technology. The core portfolio consists of the Unidirectional Gateway (UGW) family, available in WF-500 and WF-600 Performance Series form factors, plus the newer DiodeCore entry-level gateway. Supporting the gateways are specialized modules: HERA provides hardware-enforced remote access, WF-Flip enables scheduled secure updates, WF-Secure Bypass allows emergency interactive remote access, WF-RSV provides remote screen viewing, Waterfall for IDS enables safe OT intrusion detection deployment, Waterfall Blackbox offers tamper-proof forensic storage, and Waterfall Central provides centralized monitoring. All products leverage proprietary hardware that physically enforces one-way data flow via fiber optics, preventing any cyber attack from penetrating OT networks.

Products and services
- Unidirectional Security Gateway (UGW) Hardware-enforced unidirectional security gateway providing absolute OT network protection with complete network visibility. Physically prevents cyber attacks from reaching OT networks by enforcing one-way data flow via fiber optic hardware. Available in WF-500 and WF-600 Performance Series form factors.
- DiodeCore (WF-600 DiodeCore) Entry-level Unidirectional Gateway designed for simpler deployment scenarios, smaller sites, and distributed facilities. A compact half-depth 1U rack-mount device using fiber optic hardware with software delivered as closed virtual machine images for deployment on customer virtualization infrastructure.
- HERA (Hardware-Enforced Remote Access) OT Security Remote Access Solution that provides hardware-enforced remote access to OT networks without network connectivity risks. Enables secure remote management, updates, and troubleshooting for industrial networks.
- Waterfall Central Centralized monitoring platform that enables monitoring of all Waterfall Gateways from anywhere, providing enterprise-wide visibility into security gateway status and operations.
- Waterfall for IDS Solution enabling safe deployment for OT Intrusion Detection Systems (IDS), allowing IDS integration without compromising OT network security.
- Waterfall Blackbox Tamper-proof forensic repository for storing security event data and maintaining audit trails that cannot be altered or deleted.
- WF-Flip Secure scheduled updates solution that reverses a built-in Unidirectional Security Gateway to allow safe inbound updates (such as anti-virus updates and production order updates) to OT systems on a scheduled basis.
- WF-Secure Bypass (SBP) Emergency interactive remote access module installed in parallel with a Unidirectional Gateway. When activated by a key, it creates a temporary bidirectional connection for pre-programmed periods (typically 30-90 minutes) before physically disconnecting.
- WF-RSV (Remote Screen View) Safe remote monitoring solution that sends video feeds of industrial screens through Unidirectional Gateway hardware to a web server for use by remote third parties such as vendors, enabling 'escorted remote access' with full control retained by the industrial site. Certified to Common Criteria EAL 4+, ANSSI CSPN, NITES Singapore, Korean KC, and Israel NISA standards.
