Secure Swiss Utility Network (SSUN).

Would you like to reliably secure your energy infrastructure while connecting it more efficiently?
Discover the Secure Swiss Utility Network (SSUN) – an isolated, high-security network based on SCION technology. SSUN connects energy suppliers, platforms, and cloud applications in a protected environment, far away from the public internet.

Benefit from a network that combines DDoS protection, path control, and Swiss data sovereignty. Whether for remote access, IoT, smart grids, or national data platforms, SSUN provides the foundation for resilient, future-proof communication between network operators, platform providers, and service providers.

“Do you want to reliably secure critical infrastructure? Then let's start the journey to SSUN together.”

How does SSUN work?

The Secure Swiss Utility Network (SSUN) uses SCION technology to create an isolated and highly secure communications infrastructure for energy suppliers. Participants such as network operators, platform providers, and service providers connect via EDGEs (routers), which enable secure access to critical infrastructure without complex configurations.

All data traffic is automatically routed via the SCION network. This keeps communications strictly separate from the public internet. This significantly increases availability while protecting against DDoS attacks, BGP hijacking, and zero-day vulnerabilities.

In addition, SSUN ensures maximum transparency and control through path control, certificate-based authentication, and geographically controlled data flows (geofencing). The security architecture significantly reduces the attack surface—a key advantage for operators of critical infrastructures.

The result is a trustworthy, resilient network environment that sustainably meets the growing demands of the energy industry.

Offer - EDGE-to-EDGE Encryption.

The latest software version enables EDGE-to-EDGE encryption on SCION. This feature is already being actively used by some SSFN participants. Further detailed information can be found on the Anapaya website

 

EDGE-to-EDGE encryption not only significantly increases data traffic security, but also reduces operating costs and increases availability to external partners. True to the motto: reducing complexity and costs while increasing security, stability, and availability.

 

The following points are required in order to use the “EDGE-to-EDGE Encryption” feature:

  • Ordering the Anapaya Pro license from Cyberlink (contract amendment)
  • Software version v0.39.0 (Cyberlink plans to roll out version v0.40.6 in February)
  • The respective connection partner also has an Anapaya Pro license and the required software version
  • Configuration of the connection on both sides

 

 

If you order the Pro license by March 31, 2026 at the latest, we will cover your additional costs for the first three months.

Webinar on demand - Bringing SCION to Microsoft Azure

In this webinar recording, experts from Anapaya and Cyberlink show you how to connect Microsoft Azure services to the SCION Internet architecture. They will guide you through the configuration and deployment process and then show you how SCION adds value to cloud applications by ensuring trusted connectivity and complete data path control. These benefits are not possible with the traditional internet.

In this practical webinar, you will learn:

What technical steps are required to connect Azure workloads via SCION.

How SCION improves security, sovereignty, and reliability for cloud-based applications.

What real-world use cases SCION already enables today.

How SCION supports compliance and operational continuity for critical workloads.
