In-depth Analysis of Wildcard SSL Vs. Multi Domain SSL (SAN/UCC) Vs. Multi-Domain Wildcard SSL Certificates

The growing trend of utilizing SSL Certificates to secure websites, financial transactions, sensitive information, etc.… shows how SSL is playing an important role regarding web security. The list of trusted Certificate Authorities, i.e. (CA), such as Symantec, GeoTrust, Comodo, Thawte, and RapidSSL is the main vendors who are offering SSL certificates presently.

SSL certificates are offered in three types: (1) Domain Validation, DV (2) Organization Validation, OV (3) Extended Validation, EV.

The Wildcard and Multi-Domain SSL (SAN/UCC SSL Certificate) are additional features offered by various Certificate Authority’s (CAs) that provides users with some flexibility on their domain(s) being secured via SSL.

Wildcard and Multi-Domain SSL (SAN) Certificate Explanation


  • Wildcard SSL Certificate – A Wildcard SSL Certificate allows users to secure an unlimited number of sub-domains – at a specific level – for one domain on one certificate.
  • Multi-Domain (SAN/UCC) SSL Certificate – A Multi Domain SSL certificate allows users to secure multiple Fully Qualified Domain Names (FQDN) on one certificate.


Wildcard SSL vs Multi-Domain SAN SSL

SAN Certificate Vs. Wildcard SSL Certificate Limitations

  • Wildcard SSL certificates (relating to any Certificate Authority) can secure an unlimited amount of sub-domains at only one specific sub-domain level. In other words, if you need unlimited sub-domain coverage at multiple levels (i.e. * and *, you’ll need to purchase an additional certificate.
  • Multi-Domain (SAN/UCC) SSL certificates can secure multiple domains up to a specific amount (i.e. 100), depending on the issuing Certificate Authority. For example, GeoTrust and Comodo allow users to secure up to 100 multiple domains under a single MDC SSL. However, Symantec and Thawte only allow the user to secure up to 25 additional domains. They’re also called Unified Communications SSL certificates.

Wildcard SSL or Multi-Domain SAN/UCC SSL certificate… which one to select?

Selecting which certificate may be confusing without our help. Please see below for some suggestions depending on your particular situation:

  • Users with 5 or more different sub-domains should select a Wildcard Certificate for convenience reasons, especially if you intend to add more in the near future. As for what validation type to select – Domain or Organization – this depends on how much online trust you wish to display to your visitors. If your website is a genuine business and engages in E-commerce, Organization Validation would be best!
  • Users with 2 or more unique Fully Qualified Domain Names (FQDN) should select a Multi-Domain Certificate. If you’re running a reputable online business, selecting Organization or Extended Validated Multi-Domain Certificates would be highly recommended.

  • The Multi-Domain SSL option allows the user to secure a wildcard domain. (Illustrated in Example).
  • Wildcard Certificates are only available with Domain and Organization Validation.
  • Multi-Domain Certificates are available in all validation types: Domain, Organization, & Extended Validation.
  • With Multi-Domain SSL, users have the ability to add, edit, or delete additional domains throughout the certificate life-cycle.
