S3NS SUMMIT 2026: SCALING TRUSTED CLOUD

Published on 02/19/2026

On February 17, 2026, the Palais Brongniart buzzed with the energy of innovation and security. For its 4th edition, the S3NS Summit brought together 1,300 participants around a clear ambition: making "Trusted Cloud" (Cloud de Confiance) the engine of growth for businesses and institutions.

An opening keynote driven by national ambition

The morning began with a plenary session, featuring Patrice Caine, Chairman and CEO of Thales; Anne Le Hénanff, Minister Delegate for Artificial Intelligence and Digital Affairs; Thomas Courbe, General Director for Enterprise (DGE); and Thomas Kurian, CEO of Google Cloud. Together, they reaffirmed that data security is no longer an option, but the very foundation of our competitiveness.

S3NS is no longer just a vision; it is an industrial tool ready for the most critical use cases. With PREMI3NS, we offer the technological power of Google Cloud within an environment where we control every link in the security chain.

Trusted Cloud is not a theoretical promise but a concrete tool for users, a lever for transforming organizations and companies. It enables rapid innovation within a framework of trust.

Minister Delegate for Artificial Intelligence and Digital Affairs

This ministerial intervention highlighted that 2026 will be the year of mass deployment for SecNumCloud 3.2 qualified solutions.

A catalyst for the digital ecosystem: from infrastructure to AI

S3NS is reaching a new stage of maturity. With 30 services now available on PREMI3NS, our cloud offering covers the operational needs for the most demanding enterprises.

The event was also marked by a major announcement: the arrival of Vertex AI Model Garden on PREMI3NS starting in 2026. This first building block will allow organizations to harness the power of Generative AI within a framework of total trust, ahead of the progressive rollout of other suite services.

This commitment was supported by 40 conferences held throughout the day and the presence of 28 service partners and software vendors. Industry leaders took the stage to share their insights:

Pigment: For driving business planning without compromising on compliance.
Posos: For using AI to accelerate medication management in hospitals and pharmacies.
Qonto: For streamlining electronic invoicing while protecting SMEs' financial data.
Memority, DQE... many players proving that security is the essential bedrock of digital trust.

PREMI3NS: The "Triple Crown" of compliance

The Summit provided the opportunity to officialize a major milestone. In addition to its SecNumCloud qualification, the PREMI3NS service offering is now ISO 27001 and HDSv2 (Health Data Hosting) certified. This announcement demonstrates:

Exemplary Governance: ISO 27001 certification confirms that the information security management system meets the most demanding market standards.
Healthcare Expertise: HDS certification ensures compliance with the French Public Health Code and meets strict legal obligations regarding the hosting of personal health data.
Continuous Commitment: This achievement proves our teams' determination to strengthen security measures for our clients and satisfy all regulatory requirements.

Moving from technology to expertise

Because technology is nothing without human expertise, S3NS announced the launch of the "Trusted Cloud Leader" curriculum. Complementing Google Cloud’s "Cloud Digital Leader" path and leveraging the pedagogical expertise of SFEIR, this program is designed for IT executives who wish to master cutting-edge technology fundamentals alongside a deep understanding of cybersecurity. In-person sessions will begin in April, with a virtual version available by summer.

The ambition of S3NS was to provide the market with a Trusted Cloud that benefits from both performance and SecNumCloud security. This is now a reality. SecNumCloud is not just for large groups and Operators of Vital Importance (OIVs). Our conviction is that SecNumCloud is a standard that must benefit everyone... It is a perfectly mastered strategic business decision that allows for acceleration.

An immersive experience: addressing all use cases

The major innovation of this 2026 edition was its ability to address a wide diversity of business challenges. The S3NS Summit demonstrated that Trusted Cloud now encompasses all sectoral needs, from public data management to critical industrial infrastructure. Through a sector-based approach, visitors followed five thematic tracks for a 2.5-hour deep dive into their ecosystem via co-creation workshops and concrete demonstrations:

Banking & Insurance (sponsored by Deloitte): Securely transforming financial services.
Public Sector (sponsored by Thales): Accelerating the digitalization of citizen services.
Industry & Defense (sponsored by Accenture): Protecting intellectual property and strategic data.
Health & Social (sponsored by Sopra Steria): Guaranteeing absolute confidentiality of medical data.

What’s next?

The success of this S3NS Summit confirms that innovative companies are ready to scale. S3NS reaffirms its role as a strategic partner, enabling organizations to innovate without limits, with the certainty that their most sensitive data remains under European legal protection and compliance.

Our aspiration for 2030 is clear: to consolidate this momentum and make S3NS the central pillar of Trusted Cloud in Europe, supporting the digital transformation of all strategic industries toward a model combining world-class performance and absolute security.
