Waterfall(iSecurity)

Waterfall Security Solutions is an Israeli industrial cybersecurity company founded in 2007 and headquartered in Rosh HaAyin, Israel. The company specializes in protecting critical infrastructure and Operational Technology (OT) environments, serving sectors such as power generation, oil and gas, water utilities, rail transportation, manufacturing, and other industrial operations.

Waterfall is best known for its Unidirectional Security Gateway technology, often referred to as a data diode. Unlike traditional firewalls that rely primarily on software controls, Waterfall's solution uses hardware-enforced one-way communication to allow data to flow from OT networks to IT networks while physically preventing any reverse connection into critical industrial systems. This approach significantly reduces the risk of ransomware, remote intrusions, advanced persistent threats (APTs), and other cyberattacks targeting industrial environments.

As industries increasingly connect operational assets to corporate networks and cloud services, Waterfall has expanded its portfolio to include secure remote access, OT visibility, and data-sharing solutions. These capabilities enable organizations to maintain strong network segmentation while supporting operational efficiency and digital transformation initiatives. Today, Waterfall's technologies are deployed at more than a thousand critical infrastructure sites worldwide, making the company a recognized leader in OT and industrial cybersecurity.
