Wildcard SSL Certificate

An SSL certificate that helps server administrators save hundreds or even thousands of dollars on SSL Certificates by enabling them to install the same certificate to multiple websites and/or on multiple servers at no additional cost. In general, Wildcard Certificates can only be used to secure first-level sub-domains of the domain to which they are issued. For example, a standard Wildcard Certificate is issued to *.domain.com. Once that certificate is installed on the servers, users can connect securely to www.domain.com, mail.domain.com, autodiscover.domain.com, etc.
