Thésée Datacenter is a French data-centre provider offering secure, high-performance and sovereign hosting for critical data. Its facilities in Île-de-France are certified Tier IV, with stated availability of 99.999%, and the company also highlights HDS certification and GAIA-X Level 3 labelling. Its services are designed for organisations seeking resilient infrastructure, strong data protection and operational continuity.

The company operates two data-centre sites, TDC01 and TDC02, with dual-site redundancy and support for disaster recovery and business continuity plans. Facilities are described as high-density and scalable, with electrical capacity suited to demanding workloads, including high-performance computing. Security measures include ISO 27001, video surveillance, biometric controls, multiple levels of physical access and early fire detection. Thésée Datacenter also provides carrier-neutral connectivity and fibre access.

Energy efficiency is central to its approach. The facilities use indirect free cooling and an adiabatic system, and the company reports a power usage effectiveness (PUE) below 1.2. With locations in Aubergenville and Voisins-le-Bretonneux, Thésée Datacenter combines infrastructure resilience, security and energy-conscious operation for data hosting needs.
