What Cegelec Défense does

Cegelec Défense is a French defense and security systems integrator headquartered in Toulouse and a 100% subsidiary of VINCI Energies (the energy and digital arm of the VINCI Group). The company operates seven business units—Mobile Technical Units, Infrastructures & Réseaux, Protection & Sécurité, Mechatronics Solutions, Cegelec Marine, SIEPEL, and Systèmes d'Information & Cybersécurité—delivering hardened infrastructure, kinetic/EMP hardening, CBRNe protection, secure IT systems, EMC and cybersecurity, naval maintenance, and precision mechatronics to the French Ministry of Defense, DGA, DIRISI, CEA, French Armed Forces, CNES, SNCF, and defense primes such as Thales.

The portfolio spans deployable shelters and command posts, mobile water purification (40–400 m³/day), climate test chambers (-40°C to +70°C, 40-tonne load), the patented SNA antenna stabilizer with 220° pointing range, SPALAX-NG nuclear detection systems integrated with CEA, stabilized and tracking turrets, the SNCF-validated SIMEF brake test bench, and large TEMPEST/Faraday chambers (notably a 30m × 20m × 18m unit for CNES). The company is ISO 9001 certified for mechatronics since 2008, designated as a French High-Security Establishment (ERR), holds secret/NATO clearance across all premises, and complies with LPM 2024-2030, IGI 1300, II 901, IM 900, and NIS 2.

Revenue is generated through four streams: project-based defense and security systems integration (hardened infrastructure, mobile units, security systems), long-term Maintenance in Operational Conditions (MCO/MOC) contracts, hardware sales of manufactured mechatronics products (turrets, positioners, railway test benches), and naval maintenance/refit services via Cegelec Marine. Distribution is direct to government and defense prime clients, primarily domestic (France) with international export of mechatronics products. The model is enterprise field sales with long procurement cycles tied to classified security clearances.
