EasySec Solutions is an Israeli cybersecurity company based in Jerusalem that develops the ThinGUARD platform, an OT-native zero-trust security solution designed for critical infrastructure and industrial organizations. The platform is built to secure connected devices within operational technology (OT) networks, addressing the cybersecurity challenges introduced by Industry 4.0 and Industrial IoT (IIoT) adoption. ThinGUARD operates on a zero-trust model with the principle of "Never Trust, Always Verify," extending access control enforcement down to the individual device level rather than relying solely on network perimeter defenses. This approach is intended to protect against insider threats, lateral movement attacks, and unauthorized device discovery within OT environments. Key capabilities of the ThinGUARD platform include device-level access control, endpoint-to-endpoint encryption for traffic between communicating devices inside the OT network, supply chain protection to detect and alert on rogue device traffic or backdoor activity, and a centralized control and monitoring system (CCMS) capable of managing large-scale deployments of connected devices globally. The platform also supports business-based access control using auto-generated device tags such as location, device type, model, and manufacturer to define logical groups. It is designed to support both legacy and new-generation industrial devices, with an emphasis on maintaining availability — a critical requirement in operational environments. The solution targets critical infrastructure operators and industrial manufacturers undergoing digital transformation.
