Does your organization own and manage multiple fully qualified domains (FQDN) and subdomains? If so, getting individual SSL certificates for each of them will be extremely expensive and difficult to manage. 

That’s where the Wildcard SAN Certificate comes in. 

An SSL SAN Certificate is the perfect certificate for those who want a simplified SSL infrastructure for all of their domains and subdomains. In this article, we discuss what is Wildcard SAN Certificate and what are their key advantages. 

What is Multi-Domain Wildcard SAN Certificate?

Wildcard SAN SSL is one in which you can secure a multiple fully qualified domains (FQDN) and subdomains with a single certificate. For example, the same certificate can secure blog.website.com, mail.website.com, blog.domain.com, mail.domain.com, or any other subdomains or primary domains.

Depending on the CA, a Wildcard SAN SSL can secure 25, 100, or even 250 domains and all accompanying subdomains simultaneously.

How Multi-Domain Wildcard SSL Works

A Multi-Domain Wildcard SSL is used to secure both FQDNs and wildcard domain names within SAN entries. 

Let’s say the common name of a website is website.com. In that case, you can create the following SAN entries: 

*.domain.org 

www.education.net 

*.mail.website.com 

website.edu 

It’s the perfect SSL for the following situations:

  • If you want to also secure the wildcard version of a common name. This can be done with an additional SAN. 
  • If you want to remove or add any domain or subdomain easily. You can do so by removing or adding them any time within the validity period. 

A few points to note regarding Multi-Domain Wildcard SSL:

  • All the domains are related to a single certificate. 
  • It doesn’t automatically secure the non-www version of the primary domain. 
  • It is only available on DV and OV certificates. 
  • You must specifically mention if you want to cover the wildcard version of the Common Name. 

Advantages of SSL SAN Wildcard 

The following are some of the prime advantages of SSL SAN Wildcard certificates:

  • Extremely flexible — you can cover multiple domains and subdomains. The exact number of maximum domains depends on the CA.
  • It’s far cheaper than buying all the SSL certificates individually. 
  • You have to go through the vetting process only once for all the domains and subdomains, making it time-efficient. 
  • Both DV (Domain Validated) and OV (Organization Validated) Multi-Domain Wildcard SAN certificates are available. 
  • Cuts down administrative costs. 
  • SSL San Wildcard is a future-proof solution. As you acquire more domains and subdomains, you can secure them with the same certificate without further vetting.
