SSL Certificate?

What is a Wildcard SSL Certificate? 

A Wildcard SSL certificate is a single certificate with a wildcard character (*) in the domain name field. This allows the certificate to secure a single domain and multiple subdomains.

For example, a Wildcard SSL certificate for *, could be used for,,, in addition to any other subdomain name.

What is the price of a Wildcard SSL certificate?

The price of a Wildcard SSL certificate is determined based on the number of subdomains you secure and the number of years of coverage you select. With DigiCert you can secure up to 250 subdomains. Check the wildcard SSL certificate price here or by logging into your DigiCert CertCentral® account.

What is the difference between a multi-domain SAN Certificate and a Wildcard SAN SSL Certificate?

A multi-domain subject alternative name (SAN) certificate, also known as a multi-domain certificate, can support multiple domains and multiple host names with domains. Multi-domain SAN SSL certificates are more flexible than wildcard SAN certificates since they are not limited to a single domain. Currently, all DigiCert TLS/SSL certificates can be converted to a wildcard SAN or a multi-domain SAN certificate. Combining the functionality of both allows you to secure a much broader set of domains along with the capability to use them on any number of subdomains.
