The Best 7 SAN Certificates to Secure Your Alternative Domains

The Norton Secured Site seal is no longer offered starting Oct. 16, 2023.

Our research shows that nearly 34% of the top 10 million websites using SSL/TLS encryption use SAN certificates to secure 3 or more domains. Our team at RapidSSLonline.com has put together a list of the 7 best and most affordable SAN SSL certificates in 2021 to help you pick the most affordable SAN certificate

When your organization has numerous domains online, buying and managing SSL certificates for each of them separately becomes a hassle. In addition to having to continually renew all these certificates, you also have to track all of their individual renewal dates (which might be different for all the certificates). All of these repetitive chores become a huge burden for entrepreneurs and small businesses’ IT admins. The good news is that there’s a practical solution for this problem: a SAN certificate.

A SAN certificate — or subject alternative name certificate — helps you secure many SAN domains under a single SSL/TLS certificate. So, if you have the website mydomain.com and want to secure mydomain.co.uk and mydomain.net, you could secure all of them (and many others) under the same single certificate. This simplifies your PKI certificate management responsibilities and helps you to avoid outages, insecure connections, and other security-related issues.

We’ve put together a list of the seven best SAN SSL certificates in 2021. This way, you can make an informed decision of what’s the best SAN SSL to meet your organization’s website security needs.

Frequently Asked Questions on SAN SSL Certificates (FAQs)

What is a SAN certificate?

A subject alternative name (SAN) SSL certificate is capable of securing up to a total of 250 fully qualified domain names (FQDNs), IP addresses, and specified subdomains under a single certificate. If you have multiple domain names for your enterprise, SAN certificates will be a convenient option for you.

How do SAN certificates work?

A SAN certificate can secure one primary domain and many other SAN domains under a single certificate. You can enter the additional SAN names when you buy the certificate, or you can also manually add via the certificate’s subject alternative name field at a later date.

Which certificate should I buy if I own multiply domain names and all of their subdomains?

If you want to secure all of your SAN domains (up to 250) and an unlimited number of subdomains under them, you should buy a multi-domain wildcard certificate. This SAN certificate saves time and effort in the administration of the SSL certificate.

What are the advantages of a SAN certificate?

There are many advantages of SAN certificates. Let’s look at some of them:

• A SAN certificate offers greater flexibility and scalability than traditional single domain certificates.
• It’s simpler to manage one SAN certificate instead of multiple individual SSL certificates.
• It’s easier to renew the SAN certificate.
• The cost of purchasing a single SAN certificate is often cheaper than multiple SSL certificates.

Which is the most reliable SAN certificate provider?
