Wildcard SSL

Secure unlimited subdomains on a single IP address

A standard SSL Certificate is issued to a single Fully Qualified Domain Name (e.g., www.yourdomain.com) only, which means it can only be used to secure the exact domain to which it has been issued.

A WildcardSSL Certificate is issued to *.yourdomain.com, allowing the certificate to be used on an unlimited number of subdomains and across an unlimited number of servers. The one-time cost of the certificate covers you for additional subdomains or servers you may add in the future.

GlobalSign Wildcard SSL is an option available for DomainSSL and OrganizationSSL Certificates. Just select the Wildcard SSL option during the certificate application.

How Does a Wildcard SSL Certificate Work?

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

For example:

Can be used to secure:

  • www.yourdomain.com

  • anything.yourdomain.com
