If you’re not sure what SAN certificates are or whether you need them, ask yourself a few important questions:
- Do you own multiple websites?
- Do you own websites with different top-level domains (e.g. .com, .in, .ca, .net, .org, .tech, .io, etc.)?
- Do you want to save time, money, and labor hours?
If your answer to any of these questions is yes, then you’ve come to the right place. In this article, we’ll answer your question “what is a SAN SSL certificate?” We’ll also explore what SAN certificates do, what their benefits are, and which SAN SSL certificates offer you the greatest advantages at the best prices
What is a SAN SSL Certificate and Why Do You Need One?
In the context of an SSL certificate, the subject alternative name (SAN) is a type of SSL certificate that is capable of securing multiple domains under a single certificate. A client can append a certificate with multiple subject names or domain names (up to 250) during the certificate’s validity period. Hence, they are called SAN certificates.
A single SAN SSL certificate has the capacity to secure all below domain names under the single certificate roof:
Wildcards, on the other hand, can only secure a single domain and an unlimited number of subdomains on a single level.
But what else do SAN certificates offer?
Your Choice of Validation Level
SAN certificates are available in all three validation types. Domain validation (DV) is designed specifically for freelancers, startups, bloggers, and small businesses that don’t collect or handle customers’ personal information. Organization validation (OV) and extended validation (EV) are high-end certificates designed for companies that are legally registered and have physical addresses.
Multi-Level Subdomain Coverage
Any level of subdomains can be added as additional SANs under the SAN certificate. For example, if you own mysite.com, blog.mysite.com, posts.blog.mysite.com, suscription.blog.mysite.com, traveling.post.blog.mysite.com, etc., you can secure all of these subdomains under the same SAN SSL certificate.
Coverage of Domains with Different TLDs
It’s a very common practice for businesses to buy domain names with multiple TLDs to protect their brand name and get the benefit of Google’s localized search results. But getting separate SSL certificates for each domain sporting a different TLD used to be very expensive and time consuming. That’s why virtually all of the major certificate authorities (CAs) offer SAN certificates that can include all of the domain names with different TLDs under the same SSL certificate.
Simplified Certificate Management
Let’s be honest here. SSL certificate management is not like a certain Ray Romano TV character — not everyone loves it. It includes certificate signing request (CSR) generation, validation, and installation processes — all of which are tedious and time consuming when you have to do it for every domain individually. If you make a single mistake, all the browsers will go crazy and show different types of SSL related error pages when someone tries to visit your website.
Plus, you must keep track of the expiry date and renew the certificate before it expires. Otherwise, the browsers will show a pesky security warning page with the “SEC_ERROR_EXPIRED_CERTIFICATE” message that can drive away your prospective or current customers. The renewal process is the same as buying a new SSL certificate!
The following screenshot of a frustrated customer’s post was taken from a leading SSL provider’s certificate renewal page:
Image how frustrating it would be for that person to have to generate a CSR, pass the validation process, and install the SSL certificate 13 times! Unfortunately, autorenewal is still not available for security reasons. But do you see our point? Unless you own multiple websites and have loads of extra money available to waste, then buying a single-domain SSL certificate for each site individually is not a wise decision.
This is where a SAN SSL certificate can rescue you! When all of your websites are secured under a single SSL certificate, you just need to go through the entire certificate management process for one time — for all the websites — no matter whether it’s for five, 15, or 100 websites! Peace!
The Best Industry Savings
Another huge advantage of buying one SAN SSL certificate is that it would save you money. Buying one SAN SSL certificate would cost you less than buying a separate single domain certificate for every domain. Plus, you will save a significant amount of time and labor in the certificate management process, as stated in the above point.
