For too long, European organisations have been forced into a compromise: accept the performance of global CDNs while inheriting their legal and sovereignty risks. Most global providers operate as an opaque ‘black box’; you have limited visibility into where traffic is routed or who has access to logs. Between the US CLOUD Act and the tightening requirements of NIS2, this lack of control has turned a technical headache into a significant compliance liability.
Varnish CDN is a fully Europe-hosted, sovereign Content Delivery Network (CDN) designed for organisations that refuse to choose between world-class speed and legal certainty. Built on the industry-leading Varnish Enterprise engine, it ensures your traffic, your logs, and your data stay exactly where they belong: inside Europe.
In the discourse around European digital sovereignty, the spotlight has focused heavily on data residency: the physical location where data sits at rest. CIOs have spent years migrating to local cloud hyperscalers to satisfy GDPR and NIS2.
Data residency only solves half the puzzle.
A CDN is a distributed network of servers that caches your content closer to the end-user to reduce latency and handle traffic spikes. Many organisations meticulously secure their storage in Europe, but inadvertently route that same data through CDNs subject to US jurisdiction. You can lock the warehouse, but if the delivery mechanism is subject to the US CLOUD Act, your sovereignty is an illusion.
Varnish CDN was built to be your definitive European infrastructure partner. It provides a sovereign technology stack that offers the scaling capabilities of major US providers without the attendant regulatory risk:
Zero US CLOUD Act Exposure: We remove the risk of extra-territorial data access that global vendors cannot guarantee.
NIS2 Ready: Meet your supply chain obligations with local log retention and full-path observability.
Predictable Routing: Our traffic stays within European ISP topology, ensuring stable latency and predictable paths.
A comprehensive beta phase with Schibsted, one of Europe’s largest media groups, validated our three core pillars:
Varnish CDN is a programmable engine for the modern web. Get started in a matter of minutes: sign up for an account, define your origin (the server where your content lives), and update your DNS to point your web service to the Varnish CDN endpoint.
The NIS2 Directive (Article 21 & Recital 90) explicitly mandates that organisations assess and mitigate the risk of "undue influence by a third country" within their digital supply chains. For high-trust sectors, relying on a provider exposed to extra-territorial data requests is no longer a viable strategy. Varnish CDN can provide the architectural evidence you need for regulators:
Incident Reporting: Local log retention for transparent audits.
Risk Management: Protection under the EU/EEA legal framework.
Transparency: No hidden third-party routing paths.
Historically, achieving this level of control meant building and managing a private CDN. We’ve changed that. We have taken Varnish’s industry-leading caching engine and packaged it as a code-free SaaS solution.
Sovereign infrastructure should be accessible. With zero-friction, you can go live in minutes via a streamlined dashboard, no complex infrastructure management required.
Choose the right tier for your mission:
Start Free: Perfect for testing, small sites, and Proof of Concepts.
Developer & Growth: For commercial sites and high-velocity APIs.
Business & Enterprise: Security-rich bundle for the most demanding business-critical operations.
The shift toward trusted European digital infrastructure is a requirement for the modern era. Varnish CDN provides the speed your users demand with the sovereignty your legal team requires.
