Secure Sockets Layer, or SSL, is a protocol that is used to encrypt the information exchanged between a hosting server and its users. The practical application of using an SSL is to protect the information which visitors submit on your website - a login page, a payment page if you run an online store, and so on. Any information they type in in any box on the site shall be submitted securely to the server, so their login or payment details shall be protected from being accessed by unauthorized individuals. Typically, an SSL certificate needs a dedicated IP address to be installed, which suggests the overall cost for your online presence shall be bigger. While this might not be a problem for a larger firm, it might matter for a non-profit organization or a small online store which does not generate big income if additional money should be spent. This is the main 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 install an SSL certificate.
