SSL Certificates for Unlimited Servers and Subdomains
Wildcard certificates use Subject Alternative Names (SANs) to secure a domain and all of its first-level subdomains. For example, a certificate for *.example.com secures www.example.com, mail.example.com, etc. A standard SSL Certificate would only secure www.example.com, requiring you to purchase an additional certificate for mail.example.com. And every DigiCert wildcard certificate comes with an unlimited server license, so you only pay oncewhether you have one server or one hundred.
