About us

Your single point of contact for the security and dependability of your products and systems.

Because Cybersecurity and Dependability are intricately linked, and the Security of connected objects has to be managed at system level, SERMA Safety & Security has developed a one-stop comprehensive offer incorporating Expertise, Evaluation, Consultancy and Training, covering hardware, software and information systems.

Created in 2015, SERMA Safety & Security, known as S3, is renowned for its expertise in the field of safety and security – the result of over 20 years’ experience:

  • ITSEF (Information Technology Security Evaluation Facility) created in 1998 , which carries out several hundred security evaluations each year in France and abroad (ranging from electronic chips to the full electronic system)
  • A specialised business line devoted to Consultancy, Training and Expertise, carried over from Surlog and OPALE Security, two firms that have since been integrated into the company

100 employees

5 sites: Pessac (33), Guyancourt (78), Rennes (35), Angers (49) and Toulouse (31)

25% of business activities devoted to Research & Development

30% of revenue from international activities
