Multi-Domain SSL Certificates

Secure 250 separate domains, IPs or SANs with one multi domain certificate

A Multi-Domain SSL Certificate gives you complete versatility-it streamlines management. Easily secure multiple domains, sub-domains, external IP addresses and other environments on a single certificate throughout its entire lifecycle. This effectively streamlines the management of your certificates by syncing up certificate expiration dates and reducing installations.

What is Multi-Domain SSL?

Plain and simple, it's certificate management made simple. Secure 250 different domains/IPs on a single certificate-it doesn't get any easier. Whether your web presence consists of just a couple of domains and sub-domains, or you're managing a massive infrastructure-certificate management can be a huge pain. Multi-Domain SSL certificates help alleviate this burden by giving you the flexibility to secure multiple domains, sub-domains, external IPs and server environments simultaneously with just a single certificate throughout its lifespan.

How does Multi-Domain SSL work?

When you generate your Certificate Signing Request (CSR), you list each additional IP in the Subject Alternative Name (SAN) field. Here is where you can fill out up to 250 SANs. That's the most in the industry-by far. You can do this at any time during the certificate's lifecycle, you'll just need to reissue.

Subject Alternative Names (SAN)

The SAN field functionality gives you the flexibility to secure your entire web presence at once.2-4 SANs or Subject Alternative Names are typically bundled with a Multi-Domain certificate purchase. Additional SANs can be purchased separately as needed. Best of all, over the lifespan of the certificate you can add, change or remove SANs-so the certificate can grow with your business.
