SSL Caching was developed as a measure to cope with the Mandatory Security Server Policy provision of the amended Information and Communication Act, which became effective in January 2007. A service that prevents server overload and ensures stability and improved performance when using SSL (Secure Sockets Layer) certificates, SSL Caching service processes the encryption operation of SSL authentication between the user and Web server with a separate caching service. The user and site administrator can reduce SSL authentication encryption time by 3 times or more compared to existing Web servers, while ensuring a safe security procedure and maintaining the same Web page loading speed. The introduction of the security server means that enterprise customers can solve the problem of speed degradation and server overload. They can also expect cost reduction and a higher return on investment, as there is no need for separate networks or hardware.
