This article provides you with information regarding shared and dedicated SSL certificates.
A Shared SSL Certificate is one that is shared by all users on the server. A big benefit of Shared SSL is that it is free, and it is just as secure as a Dedicated SSL Certificate. The drawback however is that the Shared SSL is assigned to the server name and IP address and not your registered domain name.
Dedicated SSL certificates are a great alternative to Share SSL Certificates. While they are not free, they do add much more peace of mind to your customers as the SSL Secured URL will look like https://YOURdomain.com
