What is the difference between UCC SSL certificates and Unlimited Wildcard Sub Domains SSL certificates?

UCC SSLs and Wildcard SSLs serve different purposes when securing website addresses.

UCC SSLs secure a limited (5,10,15, etc.) amount of specific domain names. These do not necessary need to be sub domains. For example, you may secure domain1.com, domain1.net, domain2.com and shop.domain2.com.

A Wildcard SSL only secures subdomains of the given domain name, but can secure an unlimited number of subdomains. For example, a Wildcard SSL would secure domain1.com, shop.domainX.com, email.domainX.com as well as any other subdomain of *.domainX.com, but could not secure domainY.com.

So a UCC may be a lot better deal if you need to secure multiple different domains.  A wildcard SSL may be the best choice to secure multiple sub domains on the same root domain name.

GoDaddy has great prices on both UCC and Wildcard SSLs.

Unified Communications Certificates (UCC) are SSL Certificates that secure multiple domains and multiple hostnames within a domain. They allow you to secure a primary domain, and up to 99 additional Subject Alternative Names, in a single certificate. UC Certificates are ideal for Microsoft® Exchange Server 2007, Exchange Server 2010, and Microsoft Live® Communications Server.

A Wildcard SSL certificate secures your website URL, and an unlimited number of its subdomains. A single Wildcard certificate can secure both www.coolexample.com, and blog.coolexample.com.

Wildcard certificates secure all of the subdomains at the level you specify when you submit your request. Just add an asterisk (*) in the subdomain area of the common name where you want to specify the wildcard. For example:

If you configure *.yourdomainname.com, you can secure
blog.yourdomainname.com, etc.

If you configure *.www.yourdomainname.com, you can secure
blog.www.yourdomainname.com, etc.

Wildcard certificates secure websites the same as a regular SSL certificate, and requests are processed using the same validation methods. However, some Web servers might require a unique IP address for each subdomain on the Wildcard certificate.
