Our history
SERSYS was founded in 1986 with the development of an innovative armored door featuring a built-in electric lock. In 1990, the company shifted its focus toward professional applications, developing high-performance solutions for telecommunications, property protection, fire safety, and personal protection.
Its in-house R&D department was created in 1993, and since 2009, SERSYS has operated its own assembly workshop in Taverny. In 2025, the company joined the CDVI Group, an international access control expert, allowing it to expand its reach while preserving its specialized expertise and French roots.
Today, SERSYS supports its clients with projects across mainland France, French overseas territories, and internationally.
