SSL Certificate SAN or Wildcard?

I'm wanting to cover the a few domains with an SSL Certificate. e.g.

  • portal.domain.com
  • app.domain.com
  • app1.domain.com
  • app2.domain.com

I'm a bit confused as to whether I can go for the cheaper Unified Communications Certificate, or whether I need to fork out for a wildcard certificate. Is the only difference that the wildcard can have an unlimited number of subdomains, where the UCC only covers a set number under the SANs?

Thanks in advance

Solution

  • Yes, you are right Unified Communications Certificate covers a set on SANs but it can secure multiple domains, and hosts configured in your Exchange server where a traditional wildcard SSL cannot. For e.g. A wildcard ssl can secure first level of sub-domains like *.example dot com where a Unified Communications Certificate secures www.example dot com, www.example dot net etc.
