Security at Speed

Protect the User Experience

Many security tools add friction or create bottlenecks, especially if they require additional network hops or external services.

TLS Termination and User Authentication

High-Speed TLS

Varnish Enterprise tightly integrates client-side and backend TLS with incredibly performant TLS protocol negotiation.

Mutual TLS brings security for server-to-server authentication across intranets and extranets too.

JWT and HMAC verification makes it easy to prevent unauthorized activity and validate user and server identities. Varnish can cache and invalidate authenticated requests shared across many different users, so authorization does not harm performance.

What is TLS?

Data Privacy and Sovereignty

Uphold Compliance

Legislation and regulation can mean commercial CDNs cannot guarantee data privacy or sovereignty. Varnish Enterprise software:

  • Deploys to dedicated, private servers in locations of choice, plus  EU-based cloud infrastructure
  • Restricts access via IP and location
  • Ensures data stays in specific territories on infrastructure you control
