Multi-Domain SSL Certificates

Multi-Domain SSL Certificates are the most versatile SSL solution on the market. With a single Multi-Domain certificate, you can secure up to 250 different domains. Certain Multi-Domain products also protect unlimited subdomains, solving the most complex web security challenges.

Their flexibility saves users valuable time and tons of money. Instead of spending a fortune on separate certificates for each of your domain names, you can buy a Multi-Domain SSL certificate and quickly encrypt the entire network of your sites.

When you buy a Multi-Domain SSL certificate, please note that it has two alternative names: SAN SSL and UCC SSL. SAN SSL stands for Subject Alternative Name Certificate, and UCC SSL is an acronym for Unified Communication Certificate. You will find all these names across our wide range of Multi-Domain products.

Multi-Domain SSL certificates work the same way as Single-Domain certificates, except for the number of domains they can secure. A multi-domain cert protects both your internal and external domains/subdomains under a single SSL installation and a one-time renewal period. Depending on the SSL brand you choose, the certificate will include a few additional domains by default (called SANs), as well as the option to secure multiple subdomains. If you need more domains, you can add up to 250 SANs. But that’s not all. Even if your multi-domain certificate is up and running, you can always purchase extra domains and then simply reissue your certificate.

For instance, with a Multi-Domain SSL cert that includes 3 domains by default you can secure:

Three different domains:

1. yoursite.com
2. yoursecondsite.com
3. yourthirdsite.com

Three different subdomains:

1. blog.yoursite.com
2. sotre.yoursite.com
3. membership.yoursite.com

Three different domains and subdomains:

1. yoursite.com
2. blog.yoursite.com
3. anothersite.com

Configuring your Multi-Domain certificate is easy. During the CSR (Certificate Signing Request) generation, please include your first domain. For example, yoursite.com. Right under the CSR text area, in the additional domains’ fields (SANs), specify the rest of domains or subdomains you want to encrypt. After you pass the SSL validation, you can safely install the certificate on your server.

A SAN certificate can encrypt 1 to 3 domains by default, depending on the certificate brand, and up to 250 additional SANs for an extra fee. You can request more SANs during your SSL certificate order at the checkout.

The Subject Alternative Name field is where you include additional hostnames (sites, subdomains, common names, etc.) to be encrypted by a single Multi-Domain SAN SSL certificate.

A SAN certificate secures multiple domain names under a single SSL installation, while a Wildcard certificate protects unlimited subdomains and the domain name. SAN certificates can also encrypt subdomains, but a Wildcard certificate cannot secure multiple websites.
