Which are more widely supported by browser clients, wildcard or SAN certificates?

I need to decide between using a SAN cert or a wildcard cert. Client/browser compatibility is my biggest concern.

Digicert maintains pages for compatibility with certificate types:

They note several server side compatibility problems with wildcard certificates but no client side problems. SAN certificates are problemic for some older browsers:

  • Versions of major web browsers from before 2003.
  • Older smart phones running Symbian OS
  • Older Palm Treo

If supporting these older browsers is important to you, then wildcard certificates have wider browser support.

Thanks Stephen! An excellent answer and getting a compatibility listing for both from the same source is a good way to make a comparison. I had trouble finding such a thing so I am very glad to see that Digicert provides compatibility information for both. – ghbarratt Sep 26 '13 at 19:39
