Some websites or servers have specific SSL certificate requirements. Review your business needs and server configuration, then check out Which SSL do I need?

Here’s a quick overview of the certificate types:

Standard Single Domain SSL — If you need to encrypt information for only one Web address, coolexample.com for example, use the single SSL. The single SSL works well for shopping cart sites, and is also a good way to encrypt logins on your site.

One certificate protects www.coolexample.com and coolexample.com.

Single Domains with Unlimited Sub Domains (Wildcard) SSL — With a wildcard, you can request the certificate for *.coolexample.com to secure subdomains such as photos.coolexample.com, blog.coolexample.com, email.coolexample.com, and more.

Multiple Domain UCC SSL — A multiple domain UCC certificate is ideal for Microsoft Office® Communications Server, Exchange 2007 and 2010 Server, or other enterprise applications, and single companies or entities with many related URLs. However, this certificate is not recommended for sites where content or businesses are unrelated.

If you’re still stuck on which certificate to purchase, use this graph to cross-reference the assurance you need with the number of domains or subdomains you need to secure:

After you purchase an SSL credit, how you submit the request for a certificate in your account varies depending on the type of certificate and where you’re installing the SSL.

When the certificate is issued, we send an email to let you know. What happens next depends on where you’re hosted and the options you selected when you requested the certificate.

If you selected Web Hosting, Grid Hosting, Website Builder, Quick Shopping Cart® or Dream Web Site when you requested your certificate, we automatically update the IP address for your website when your SSL is approved.

If you host your website with another provider, or you use one of our VPS or Dedicated Server solutions, see the article Installing an SSL: Server Instructions for information about installing the SSL on your server.

NOTE: For third-party hosting or a Virtual Private or dedicated hosting plan, you must reinstall a UCC certificate every time you need to add or remove a subject alternative name (SAN). Therefore, when possible, we recommend assigning all your SANs before you install the certificate. For information on adding or dropping SANs, see Adding or Dropping Subject Alternative Names from UCC Certificates.
