HDS (Hébergeur de Données de Santé)

French certification, granted by ANS, that any organization hosting personal health data on behalf of a French controller must hold.

HDSHébergeur de Données de Santé, “health-data host” — is a French certification scheme administered by ANS (Agence du Numérique en Santé) that any organization hosting personal health data on behalf of a French data controller must obtain. The legal basis is Article L.1111-8 of the French Code de la santé publique; the operational baseline is the Référentiel de certification HDS maintained by ANS.

The current referential builds on top of ISO/IEC 27001, adding sector-specific requirements: physical separation of health-data environments, French data-residency clauses, traceability of access, and personnel commitments. An HDS audit is delivered by a COFRAC-accredited certification body and runs on the same three-year cycle as ISO 27001, with annual surveillance audits.

Who needs it:

  • Any SaaS, hosting provider, or managed-services vendor that stores, processes, or operates health data for a French entity — even if the vendor itself is not French and the infrastructure sits outside France.
  • Six activity scopes are defined (physical hosting, infrastructure hosting, platform hosting, administration, backup, external archiving) — the certificate names which ones apply.
  • B2B procurement gate. French hospitals, mutuelles, and HealthTech buyers are legally barred from contracting with a non-HDS provider for in-scope workloads.

Where awareness fits: the referential explicitly requires that personnel involved in hosting activities be trained on the specific obligations of handling health data — and that the operator can demonstrate it. The format is not prescribed, which means an LMS completion log or a behavioral evidence trail both qualify on paper. The latter ages better, because the auditor returning in year two will ask whether anything changed — and a completion log shows the same flat 100% it always has.

HDS coexists with the European GDPR and is sometimes mapped against US HIPAA when a vendor sells into both markets, though the schemes are not equivalent.
