By enabling SSL/TLS in Varnish Plus, customers will gain encrypted and secure communication on both the front and backend

Oslo - June 1, 2015 - Varnish Software announced today that its Enterprise offering, Varnish Plus, now offers full SSL/TLS support on both the HTTP backend and client side. This means Varnish Plus allows customers to improve their website security without having to rely on third party solutions. As a consequence, customers can simplify their web architectures and ultimately save time and money.

By enabling SSL/TLS in Varnish Plus, customers will gain encrypted and secure communication on both the front and backend as Varnish acts as both HTTP server and client. On the client side, the HTTP server intercepts web requests before they reach a web server. The SSL/TLS support on this side enables traffic encryption between the client and Varnish.

On the backend, the HTTP client fetches content missing in the cache from the web server. This enables content to be fetched over the encrypted SSL/TLS, which particularly benefits customers who run a fully encrypted data centre or have web servers that reside in a different location to their Varnish Plus servers.

“We have seen considerable market demand for SSL/TLS from the most advanced Varnish users,” commented Per Buer, CTO and founder, Varnish Software. “Until now our customers had to rely on third party products for SSL/TLS. With the new SSL/TLS support they can get access to a highly performant SSL/TLS server bundled with Varnish Plus.”


Varnish Software will present its SSL/TLS solution for the first time on June 2nd at the Varnish Summit in Silicon Valley themed "Scaling the Heights". For more information please visit

SSL/TLS support is currently only available for Varnish Plus subscribers. For more information please contact Varnish Software.
