In the wake of the signing of the strategic partnership between Thales and Google Cloud and the creation of S3NS in 2022, this announcement delivers on the ambition shared by both groups to offer an unmatched solution on the market, now available to all public and private organizations. As a French-law company fully controlled by Thales, S3NS committed to deploying one of the most comprehensive SecNumCloud-qualified solutions on the market within three years of its creation. This commitment has now been fulfilled.
The SecNumCloud framework is the most stringent cloud security standard in Europe. France is currently the only country to require its application for sensitive public-sector data, demonstrating the State’s commitment to ensuring optimal protection of French citizens’ data.
PREMI3NS is operated and administered exclusively by S3NS employees within datacenters located in France. All cloud technologies and their updates are received in a quarantine zone, analyzed and validated by S3NS, before being deployed into production within an environment that is also administered exclusively by S3NS.
They chose S3NS
PREMI3NS, SecNumCloud-qualified and available for several months through the “Early Adopters” program, is already used by around thirty pioneering customers. S3NS is currently supporting companies in the insurance sector (MGEN, Matmut, AGPM), industry (Thales, Birdz, a Veolia subsidiary), finance (Qonto, BConnect), as well as services (Club Med) in their gradual migration to the “Trusted Cloud”, leveraging the combined expertise of Thales and Google Cloud.
In addition, EDF has recently announced the selection of S3NS for the storage, processing, and enhancement of the Group’s strategic data, and Thales is already using PREMI3NS for its internal information systems and engineering developments.
