S3NS Summit 2026

This 2026 edition marks a decisive milestone: after successfully completing several hundred physical, software and legal controls, the PREMI3NS trusted cloud has reached full operational maturity and is now ready to support the most critical use cases. 

The event brings together public and private decision-makers, technology experts and partners around a key challenge: reconciling cloud performance, security and data sovereignty.

The first S3NS Summit following the SecNumCloud qualification

In a context of growing cyber threats and increasing regulatory pressure, data sovereignty and control have become strategic priorities. With its PREMI3NS offering, S3NS delivers a unique model that combines Google Cloud technologies with Thales’ cybersecurity expertise, within a sovereign framework compliant with SecNumCloud requirements, a qualification issued by ANSSI (the French National Cybersecurity Agency) for cloud service providers.

The S3NS Summit 2026 is structured around a strategic plenary session in the morning, followed by conferences, demonstrations and workshops in the afternoon. 

A major new feature of this edition is a dedicated visitor experience built around 45 conferences covering the following themes:

• tech conferences led by S3NS
• AI & Innovation sessions co-hosted by S3NS and Google Cloud
• product sessions co-hosted by S3NS and Google Cloud, with a focus on cybersecurity, Deeptech, and FinOps
• AI & Innovation sessions
• sessions focused on trust, including two featuring institutional and government representatives

In addition, 16 conferences will be led by Diamond and Gold partners.
