Sesterce: sovereignty score and 8 European alternatives

Sesterce is a French company that designs and operates AI infrastructure. Its offer covers dedicated bare-metal GPU supercomputer clusters for AI training and inference, delivered with factory-built power, backup and cooling modules, and Sesterce OS, software for monitoring power, cooling and nodes on the campus. The company also develops campus-scale AI data centres, including in Valence (Drôme) and at the Bosquel site in Hauts-de-France, which it is developing together with SoftBank Group.

The company is French and its head office is in Marseille, which places it under French and EU law. Its campus projects are being developed in France and Finland. Bosquel is run as a joint venture with SoftBank Group, a separate entity from the operating company. The website mentions no GDPR statement or data processing agreement beyond a link to the privacy policy, and it does not describe where customer workloads are hosted. A European organisation should therefore confirm hosting locations and processing terms in writing before using the service.

Why digital sovereignty matters with Sesterce

Sesterce is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Sesterce scores best on data residency.

Sesterce is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Sesterce together with your other vendors and gives a total score, a heatmap and the main risk drivers.
