Varnish is the swiss army knife of the HTTP transport, and its flexible configuration language has long been used to thwart application attacks and DoS with custom rulesets. Varnish is fast, lightweight, aids in enabling applications to handle tremendous loads, and there are numerous security barriers in the architecture. The new Varnish Security Firewall framework enables us to rapidly secure web applications, and how it allows for easy and fast rule writing to enhance the security and quickly react to attacks. This approach lends itself well to securing cloud applications.
