coTer numérique 2026

Digital sovereignty is not just about the location of a data center.

It raises some key questions: Who operates the infrastructure? What regulations apply to the data? Where is it processed? Does an organization truly retain control over its communications and sensitive information?

Against a backdrop marked by rising cyber threats, stricter regulatory requirements, and the accelerating digital transformation of local communities, these issues are becoming increasingly important for local governments.

In fact, this is the theme chosen for the 35th edition of coTer Numérique: “Local Governments Facing the Challenges of Digital Sovereignty.”

Retarus is pleased to participate in this edition alongside the Hexatrust ecosystem, which brings together European stakeholders committed to building trust in the digital world.

Benoît Trémolet, VP of Sales for Western Europe at Retarus, will be on hand to discuss issues related to communication security, cybersecurity, and data sovereignty.

The Retarus Approach

For more than 30 years, Retarus has been helping public and private organizations secure their critical communications.

Our vision of sovereignty is based on concrete commitments:

• An independent European company
• Infrastructure operated in Europe
• Data processing in compliance with European requirements
• Enhanced protection of electronic communications
• Complete transparency regarding our operations and contractual commitments

Because digital trust cannot be imposed; it is built over time.

Why participate in coTer Numérique?

Every year, the Digital CoTer brings together key players in regional digital technology to discuss the issues shaping local public policy.

The event provides an opportunity for peers to exchange ideas and explore topics such as:

• Digital sovereignty
• Cybersecurity
• Regulatory Compliance
• The Resilience of Digital Services
• Innovation for Regional Development

We look forward to seeing you in Reims on June 23 and 24.
