Who is Waterfall?
Waterfall Security Solutions provides unidirectional security gateway technology that enforces one-way data flow between operational technology (OT) networks and information technology (IT) networks.
- Unidirectional security gateways for OT network protection
- Hardware-enforced one-way replication of industrial data to IT and cloud systems
- Protection of industrial control systems and critical infrastructure from inbound cyber threats
- Secure historian and data replication for operational visibility
- Industrial cybersecurity for energy, utilities, and manufacturing environments

More About Waterfall
Waterfall Security Solutions is positioned in enterprise environments where industrial control networks must remain isolated from external threats while still sharing operational data with business systems. Its offerings are typically deployed at the boundary between OT and IT networks, where organizations need to monitor plant performance, support enterprise reporting, and enable remote visibility without opening a path for inbound attacks.
The central technology associated with the company is the unidirectional gateway. These devices rely on a hardware-based design that permits data to flow in only one direction, so that software vulnerabilities on the receiving side cannot be used to reach the protected network. Replication software mirrors industrial data streams, such as process historian records and control system states, to external destinations. This architecture aligns with industrial cybersecurity frameworks that emphasize network segmentation and zone-and-conduit models, including guidance associated with the IEC 62443 family of standards.
In comparison with conventional firewalls and data diodes, unidirectional gateways are generally described as providing stronger assurance of one-way transmission because the enforcement is physical rather than policy-based. Firewalls permit bidirectional sessions under rule sets, which introduces additional attack surface. Organizations evaluating boundary protection for critical infrastructure often consider these approaches together as part of a layered defense strategy.
The business and technical significance of these offerings lies in enabling data-driven operations while reducing exposure of safety-critical and production systems. Utilities, energy producers, and industrial manufacturers use such controls to support regulatory compliance, incident containment, and continuity of operations. The company is listed in the directory under cybersecurity solutions focused on operational technology and industrial control system protection, reflecting its active product areas in OT network security and secure industrial data transfer.
