Multi-Domain SSL Certificate FAQs

If you have questions, we have answers. Just get through answers about usual questions related to multi-domain SSL under our FAQs section.
FAQs

What is the Subject Alternative Name field?

The Subject Alternative Name field allows you to add additional common names secured with a Multi-Domain SSL certificate.

How do I secure multiple domains using a single SSL certificate?

Multiple websites can be secured with a single Multi-Domain (SAN) SSL Certificate. When you purchase multi-domain SSL, you will have a SAN extension that lets you add the domain names protected by this certificate.

Why do I need SAN?

SAN SSL certificate reduces the need to manage individual certificates and allows you to secure multiple websites with a single certificate. The certificate enables the SAN option where you can place domain names that you need to secure. Managing multiple certificates can be a hectic task as certificate installation, renewal, expiry, and re-issuance are significant parts that need to be managed. SAN certificate gets you rid of multiple certificate hurdles and offers easy and single certificate management.

Where Can You See Subject Alternative Names in Action?

You can click on https padlock in the address bar where you have to browse Details > View certificate > Details > Subject Alternative Name, where you will find SAN names.

Subject Alternative Names

How do I add SAN?

You have to select several SAN fields and add specific domain names during the enrollment of the following certificates:

Which SSL Clients support Subject Alternative Names?

SAN certificate carries more than 99% browser compatibility; it supports mobile, PDAs, desktop browsers, OS, and servers like Firefox, Internet Explorer, Opera, Safari, Microsoft Edge, Netscape, Windows OS, Windows Mobile OS, Symbian OS.

What is the difference between a SAN certificate and a Wildcard certificate?

The SAN (Subject Alternative Names) certificate lets you secure multiple top-level domain names and subdomains with a single certificate. You can take a certificate for the primary domain; let’s say mydomain.com is a primary domain, and you can secure:

  • mydomain.org
  • mydomain.net
  • mail.mydomain.com
  • payment.mydomain.com
  • edu.info.mydomain.com

On the other hand, wildcard SSL allows you to secure unlimited subdomains under a unique top-level domain name. If you take one wildcard SSL certificate for *.mydomain.com, then you can secure,

  • www.mydomain.com
  • news.mydomain.com
  • blog.mydomain.com
  • payment.mydomain.com
  • anysub.mydomain.com

A single asterisk (*) protects unlimited subdomains under a single fully qualified domain name.

Can I get a SAN certificate for internal names and reserved IP addresses?

As per the CA/Browser certificate issuance guideline on July 1, 2012, SAN certificates cannot be issued to internal server names and reserved IP addresses.
