 “FirmGuard” is a series of cyber security protection products independently developed by Shanghai Engineering Science &Technology Co., Ltd. and China Techenergy Co.,Ltd., both of which are subsidiaries of CGN.  This series of products can meet the level-2, level-3, and level-4 safety protection requirements of nuclear power plant’s DCS system. It can provide a complete cyber security protection solution for the nuclear power plant's ‘Nerve Center’ - nuclear power DCS system, including FirmSys system, and industrial control systems in other industries.

Over the past four years, the project R&D team has been devoting themselves to research and innovate technologies, taking the “One-center, Three-protection” as their design core, integrating active defense, precise protection, situation awareness and other key technical means, adopting a variety of security measures, such as “Security Area Division, Distributed Protection, Centralized Control”, to establish a complete set of DCS system for security defense.
