GlobalSign Wildcard SSL


Wildcard SSL allows you to secure an unlimited number of subdomains on a single certificate. It’s a great solution for anyone who hosts or manages multiple sites or pages that exist on the same domain. The one-time cost of the certificate covers you for additional subdomains you may add in the future. 

Unlike a standard SSL Certificate that is issued to a single Fully Qualified Domain Name only, e.g., which means it can only be used to secure the exact domain to which it has been issued, a Wildcard SSL Certificate is issued to *, where the asterisk represents all possible subdomains.

GlobalSign Wildcard SSL is an option available for DomainSSL and OrganizationSSL Certificates. 

How Does a Wildcard SSL Certificate Work?

It's simple - we issue a Certificate with a "Common Name" of * and a Subject Alternative Name (SAN) of The * (wildcard) allows the Certificate to be used on any subdomain belonging to the domain name and the SAN ensures SSL works even without a subdomain.


Multi-Domain and SANs


Multi-Domain also referred commonly as SAN Certificates, utilize Subject Alternative Names (SANs) to secure up to 100 different domain names, subdomains, and public IP addresses, using only one SSL Certificate and requiring only one IP to host the Certificate. 

We worked with Microsoft to develop an SSL Certificate specifically for use within the Exchange and Communications Server environments. A SAN SSL Certificate allows you to deploy the Domain Security feature and enable secure client access from the Internet

While Multi-Domain SSL was originally developed for Unified Communications applications, it can benefit anyone looking for the simplicity of consolidating many domain names into a single SSL Certificate and single IP address.
