A SAN certificate is an element of the web that can secure multiple domains under a single certificate. Read on to learn more about its features, uses, and benefits!

Being a cybersecurity enthusiast, you must know about SSL certificate. It is mainly used to protect the website with modern data encryption technology. The certificate secures both the website and the user data it hosts. Now imagine a scenario where you have multiple domains. If you continue to buy a certificate for each, it will cost you a lot. The best way here is using a SAN SSL certificate.

The average annual price of an SSL certificate continues to vary depending on the type and level of validation. Likewise, if you have ten websites, you will pay a high amount every year. That’s too much for maintaining a website. Although it is necessary, what if there was a better way? Are you interested in knowing?

Fortunately, there is a way, and that is the SAN SSL certificate. Now what is it and what does it do? How can you get one? All these key questions will be answered in this article! Let’s go ahead and find out!

What is a SAN SSL certificate?

Let’s answer the dearest question! What is a SAN certificate?

A SAN certificate, developed as a Subject Alternative Name, is a digital security certificate that allows you to protect multiple domains under a single certificate. This means that if you have multiple sites, you won’t have to get different SSL certificates for each one.

You can only get one SAN SSL certificate, and that’s it. You can list all your domains under this one to ensure optimal security of each one. Here are some key features of SAN certificates!

  1. SAN SSL certificates allow you to secure multiple sites and domains with a single dedicated IP.
  2. A SAN certificate can be used and installed on an unlimited number of servers.
  3. It can be easily reissued if a domain change is needed. This can be done at no additional cost.
  4. The SAN can be used on an infinite number of IP addresses with multiple private keys.

How does a SAN SSL certificate work?

Well, if we go further, SAN certificate is a type of SSL/TLS certificate which allows you to add the respective domains and subdomains under a single certificate which will protect them.

Domains aren’t just confined to a particular niche. They can be of different types like blogging, technology, food, e-commerce, etc.

Here are some examples of domains that can be secured under a single SAN SSL certificate!

  1. abc.com
  2. abc.net
  3. abc.org
  4. abc.info

All of these domains and many more can be protected by a single certificate.

What are the different advantages of SAN SSL certificates?

It’s pretty clear that a SAN SSL certificate is sort of a master of everything. However, it has many more benefits than just securing multiple domains for you. Here are a few!

1. Scalability is easy

Think about it! If you have a website and want to create another, you need to go through the process of issuing the SSL certificate. It can take a lot of time and effort because it’s too long.

With a SAN certificate, you can easily add or remove domains as needed. So whether you want to secure a new domain or remove an existing one from the list, it can be done in minutes.

You won’t have to first generate a CSR and then upload it to the SSL certificate provider for the certificate to be issued. Hence, facilitating the process of scaling your business.

2. Ensures domain legitimacy

Ok, it seems a bit easy to read that this SSL certificate is issued, but there’s a lot of cogs behind it. For example, if you got a SAN SSL certificate, consider yourself lucky because the validation process is very strict, especially if you chose to use OV SSL (Organization Validated SSL) and EV SSL (Extended Validated SSL).

The SAN certificate comes in all three forms of validation, such as Domain Validated, Business Validated, and Extended Validated. Domain validated certificates are issued after confirming whether the user or entity is the true owner of the domain.

Company validated certificates are issued after verifying the documents proving that the company exists by carrying out a light commercial verification. Similarly, Extended Validated are issued after a thorough verification of the legitimacy of the company. And, all of this verification is done by a trusted Certificate Authority (CA)

Therefore, a SAN SSL certificate proves that you or your business is legitimate.

3. You don’t need different IP addresses

You may have heard that for each domain you need a separate IP address. Well, that’s not the case with a SAN certificate. A single IP is enough for all your domains.

4. It’s profitable

If you compare the price of getting different SSL certificates for each domain, it will be way too expensive than buying just one SAN SSL certificate. Also, renewing them every year will put a big dent in your pocket. But with this option, you can easily get rid of this extra expense.

5. Better flexibility

The best part about a SAN certificate is that it gives you the freedom to add or remove domains without any hassle. So you can start with one domain, and as your business grows, you can add more to the list.

6. Compatible with browsers

The best thing about SAN SSL certificates is that they are compatible with almost all browsers, mobiles and other internet-connected devices. This broadens their horizon in which they can offer top-notch security. This, in turn, benefits you as you can broadcast your business to all devices.

7. You can get domains with multiple TLDs

TLDs or Top Level Domains are the final part of the domain name. For example, in www.abc.com, .com is a TLD.

With a SAN certificate, you can easily obtain domains with multiple TLDs and secure them all under one certificate. Moreover, you can keep the same domain name. For example, abc.org, abc.com, abc.net, etc.

How can you check SAN information?

If you are enthusiastic enough, here are the steps to check the SAN of a website.

  1. Press on the padlock icon in the address bar relative to the web address.
  2. Select the “certificate” option.
  3. Select the “details» and choose the tab «extensions only” option.
  4. Select the “Subject Alternate Name” in the list, and you will see the list of all SANs there.

Do I need to get a SAN certificate?

If you have several domain names, it makes sense to opt for a SAN certificate. It offers many benefits such as scalability, ease of management, and cost effectiveness that are hard to resist. Plus, it gives your business a boost of security and legitimacy.

How much does a SAN certificate cost?

There are a number of legitimate certificate authorities on the web. And the price of each of them varies depending on the features offered in a SAN certificate. Overall, the SAN certificate can cost you as little as $10.99 up to over $199.99 per year.

COMODO, SSL.com, and DigiCert are some of the online web portals that can provide you with a SAN certificate.

Conclusion

A SAN certificate is a great way to secure multiple domains under a single SSL. This gives your business the much-needed boost of security and legitimacy. Moreover, it is easy to manage and quite profitable. So if you own multiple domains, getting a SAN certificate should be your top priority.
