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