About us
Since 1975, ARCYS has supported the most demanding players in the design, manufacturing, and maintenance of secure electronic solutions for harsh environments. First known as CEIS, then AREVA Expansion, the company became ARCYS by consolidating its expertise through strategic projects and targeted acquisitions.
Based in France and active internationally, ARCYS has established itself as a key player in three demanding sectors - Defense, Civil Nuclear and Rail Transport - by capitalizing on its technical expertise from Nuclear Defense. This founding experience has allowed us to extend our know-how to other fields while maintaining high standards in terms of quality, safety and regulatory compliance.
Our DNA remains unchanged: reliability, innovation, mastery of regulatory standards, and long-term commitment alongside our customers.
