Clemessy teams achieve ISO 27001 Certification for their ISMS

In summer 2025, our teams obtained ISO 27001 certification issued by AFNOR*. This recognition rewards our deployment of an Information Security Management System (ISMS) guaranteeing the protection of sensitive data and business continuity in the face of digital risks. 

Clemessy teams have just been certified ISO 27001, the international benchmark standard for IT security. This certification attests to the robustness of the Information Security Management System (ISMS) deployed within our monitoring and control, IT engineering and industrial cybersecurity activities.

In concrete terms, the ISMS provides a framework for all policies, processes and tools designed to protect strategic information, reduce the risks associated with cyber threats and ensure business continuity, including in the event of an incident or attack.

This award objectively demonstrates Clemessy's ability to work on projects with high confidentiality and security requirements, while protecting sensitive information and securing our activities in a variety of fields:

  • Monitoring and control systems, technical supervision, real-time systems, automation
  • IT development and engineering
  • Secure IT infrastructures, technical services for cybersecurity hardening and ANSSI (National Agency for Information Systems Security ) cyber certifications in the field of military programming.

Obtaining ISO 27001 certification reflects the teams' strong commitment to digital security, continuous improvement and risk management, and rewards their collective efforts.
