COLT SCION
SECURE, VERIFIABLE, NEXT‑GENERATION CONNECTIVITY
THE CHALLENGE
Enterprises today operate in an increasingly complex and high‑risk networking environment. Cyber threats are growing in volume and sophistication, large‑scale routing incidents continue to impact global connectivity, and regulatory requirements around data security, sovereignty, and control are becoming more stringent.
Traditional Internet‑based connectivity exposes organisations to security risks such as traffic interception, route hijacking, and denial‑of‑service attacks. In addition, it provides limited transparency and control over how traffic is routed. Even private WAN services, such as IP VPN, rely on implicit trust within a single provider domain and offer limited end‑to‑end visibility and control.
For organisations handling sensitive, regulated, or mission‑critical data, these limitations introduce operational risk, reduce control, and create challenges in meeting compliance requirements.
THE SOLUTION
Colt SCION is a next‑generation networking service based on SCION (Scalability, Control, and Isolation on Next‑Generation Networks), a technology originally developed in Switzerland and widely adopted in highly secure environments such as the Swiss financial sector.
SCION introduces a fundamentally new approach to networking by creating a secure and verifiable network layer, where routing paths are explicitly defined, cryptographically protected, and fully transparent.
With Colt SCION, organisations can exchange data over trusted, controlled, and auditable paths, across single or multiple service providers.
Colt SCION provides a high‑assurance WAN foundation for organisations that require the highest levels of security, resilience, and control for critical applications and data.
KEY BENEFITS
Security by design
Protect your network against routing attacks and manipulation.

Reduced reliance on implicit trust between networks
PATH CONTROL AND VISIBILITY
Define and verify the exact end‑to‑end path your data takes across the network.
Deterministic routing behaviour
Full routing transparency and auditability
Ability to enforce geographic, regulatory, or provider‑based policies
MULTI‑PATH RESILIENCE
Use multiple network paths simultaneously to maximise availability and performance.
Instant failover without service interruption
Traffic distribution across independent routes
Improved availability for mission‑critical applications
TRUSTED CONNECTIVITY ACROSS PROVIDERS
Extend secure networking beyond a single operator domain.
Secure connectivity across multiple carriers
End‑to‑end verification of routing integrity
Consistent performance across domains
DESIGNED FOR REGULATED AND CRITICAL ENVIRONMENTS
Support strict compliance and high‑assurance requirements.
Enables data sovereignty and policy‑based routing
Supports regulated industries such as finance, healthcare, and public sector
Enables connectivity to trusted isolated domains (e.g. SSFN)
HOW COLT SCION IS DIFFERENT
Internet
Global reach and flexibility, but exposed to routing attacks and traffic hijacking, with limited control, visibility, and routing assurance
IP VPN
Reliable private connectivity within a single provider domain, with limited end‑to‑end transparency and control
SD‑WAN
Flexible overlay improving application performance, dependent on underlying transport networks
SCION (Colt)
Controlled, verifiable, multi‑path connectivity with security embedded in the network layer
