Mithril Security: sovereignty score and 8 European alternatives

Mithril Security is a company working on confidential AI, which aims to keep AI models and the data they process protected while in use. Its website lists BlindLlama, which serves AI models on GPUs in a hardened environment so that the operator cannot see user data; AICert, which uses secure hardware to bind a model to its training procedure; and AIGovTool, a monitoring tool for AI systems. Its components are published on GitHub, and BlindLlama is licensed under Apache 2.0. The website does not state whether the services are vendor-hosted or deployed by the customer.

Mithril Security SAS is located at Ris-Orangis in France according to the legal notice on its website, and French law governs its website terms. Its privacy policy names a data protection officer but contains no statement on hosting regions or on GDPR compliance for its services. For a European organisation, a French provider with publicly available source code is relevant; the hosting location and contractual terms of any managed service should still be confirmed in writing.

Why digital sovereignty matters with Mithril Security

Mithril Security 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 Mithril Security scores best on data residency.

Mithril Security 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 Mithril Security together with your other vendors and gives a total score, a heatmap and the main risk drivers.
