ABI Hosting offers SSL certificates from the following provider:

SSL stands for Secure Sockets Layer. A socket is a Unix term for a communications port between computers over any interconnection medium using any computer-to-computer protocol.

SSL is the most widely used on-line secure transaction mechanism in the world.

The SSL (secure socket layer) protocol is the web standard for encrypting communications between users and web sites. Data sent via an SSL connection is protected by encryption, a mechanism that prevents eavesdropping and tampering with any transmitted data. SSL provides businesses and consumers with the confidence that private data sent to a web site, such as credit card numbers, are kept confidential. Web server certificates are required to initialize an SSL session.

You need to have a separate IP address for each domain you want to secure. The reason for this is because a certificate is bound only to a domain name but, the SSL protocol is bound to static IP addresses; therefore, any certificate-enabled web site must have its own unique IP address. The IP can be real (routable) or internal (RFC 1918 non-routable address) and it must be unique on a server.

The SSL certificate guarantees the security of the connection between the browser and the server.
