Secure Sockets Layer, or SSL, is a protocol used to encode the info exchanged between a hosting server and its users. The practical application of using an SSL is to preserve the information that customers submit on your Internet site - a login page, a payment page if you run an Internet store, and so forth. Any information they input in any box on the Internet site shall be submitted safely and securely to the server, so their login or payment details will be protected from being accessed by unauthorized people. Normally, an SSL certificate needs a dedicated IP address to be set up, which implies the overall cost for your web presence shall be bigger. While this might not be an issue for a larger business, it may matter for a non-profit organization or a small web store that doesn't generate big profits if additional money should be spent. That is the reason why we have taken advantage of an extension referred to as Server Name Indication (SNI) and we have made it possible to use a shared server IP address to set up an SSL certificate.
