Multi-Domain SSL Certificates (UCC/SAN)
Multi-Domain SSL certificates - also known as UCC/SAN certificates - are uniquely tailored to secure multiple domains with a single certificate. The UCC/SAN moniker stands for Unified Communication Certificate and Subject Alternative Name, respectively. These certificates allow you to manage and maintain all of your websites with a single certificate instance. Extremely handy for business users, in particular.
As with every other type of certificate available via SSLTrust, there's a wealth of options on the table. From DigiCert's industry-leading certificates that will secure anything and everything you might throw them at, all the way to the more affordable - albeit no less secure - Comodo offerings. SSLTrust promises that you'll find your Multi-Domain SSL here, too.

Each and every Multi-Domain certificate featured on this page is a seal of quality in and of itself. It's always worth reiterating that all modern SSL comes with standard 256-bit encryption and that it's the extra features, support, and brand recognition that lead to a higher price.
Over the next couple of sections, we'll explain what Multi-Domain SAN is and why it might be useful for you to secure multiple domains, too. If you feel confident in your knowledge, and if you know for a fact that you need a Multi-Domain SAN SSL, however, then you may wish to scroll down to certificate descriptions, instead.
What are Multi-Domain SSL Certificates? What do they do?
In simple terms, Multi-Domain SSL certificates are used to simultaneously secure multiple websites (i.e. multiple domains). For example, a single SAN SSL certificate could protect all of the following:
- www.domain.com
- exchange.domain.com
- *.example.com
- www.example.net.au
Depending, of course, on the way you've set up your primary domain and the functionality of the website itself. As soon as you have multiple domains in action, though, it's a good time to start thinking about the potential implementation of a Multi-Domain SSL.
Now, it's worth pointing out that a Multi-Domain SSL isn't qualitatively different from any other kind of SSL certificate. Multi-Domain SSL still features the same encryption standards as a regular EV SSL, for example, and it's still going to protect any website from common data theft practices. The difference, instead, lies in coverage.
Specifically, a Multi-Domain SSL certificate uses the Subject Alternative Name protocol to extend its reach to domains that might be adjacent to your main domain. These are not subdomains, mind. A Multi-Domain SSL certificate will simply cover multiple domains that exist within the purview of your main domain. Therefore, a regular Multi-Domain SSL will not provide extended coverage to unlimited subdomains: you'll need to get a Wildcard SSL certificate for that functionality (Multi-Domain Wildcard SSL exists, read more about it below).
Depending on how your specific Multi-Domain SSL is set up, your Subject Alternative Names might include as many as a dozen different SAN items for the DNS to resolve. Multi-Domain SSL is an easy and foolproof way to get all of your domain names in order without spending more than you need to.
Though most users are unlikely to have problems with it, the upper limit of SAN instances supported by any different Multi-Domain SAN SSL Certificate is between 250 to 500 - a hard cap. Something to keep in mind, if you intend to add more of them after the initial setup.
Multi-Domain SSL Certificates in Practice
Multi-Domain SSL is particularly relevant for website owners that are finding it difficult to keep up with maintaining multiple certificates spread across multiple domains.
It's simple, really. If you're handling more than a single website, chances are that you're at a point where keeping up to date on web security on different domains is taking too much time and effort. Each and every certificate has its own lifespan, and it's going to need to be reissued after a while. For those who run several websites, this can quickly get complicated and annoying.
The good news is that there's Multi-Domain support across the board. This allows domain name owners to handle all of their websites at once and, in some cases, even add unlimited subdomains to the package. All with a single SSL/TLS solution. No need to keep tabs on multiple SSLs: their activation dates, web security, and validity caps will all be taken care of with just one certificate. Extremely handy!
It's worth pointing out that a Multi-Domain SSL certificate is available for virtually all levels of validation:

Using a Multi-Domain SSL Certificate - What is it for?
Multi-Domain SAN is often put to work on Microsoft Exchange Servers, Office Communications Servers, Mobile Device Managers, and regular multi-domain websites and intranet setups. In effect, you could use a SAN certificate to secure all domains attached to specific IP addresses. Further still, if you opt for a Wildcard Multi-Domain certificate, you can secure all of your domains and subdomains in one go.
The goal, then, is to simplify certificate maintenance without skimping on website security. If you opt for a Multi-Domain SSL certificate - even a Wildcard - you're still getting all the amenities you need to protect your web presence. It's just that a fully qualified Certificate Authority will give you one certificate to use across the board, rather than getting one SSL for each of your IP addresses or domains.
Multi-Domain SSL certificate products aren't necessarily expensive, either. In fact, Multi-Domain SSL is often the most cost-effective way to secure multiple domains. Though, your mileage may vary depending on which Certificate Authority you end up choosing.
Your most important takeaway here should be that Multi-Domain SAN certificates are perfect for when you need to secure multiple websites, but don't want to have to manage multiple separate certificates. One SSL certificate can handle all of that, and then some.
Multi-Domain SSL vs Wildcard SSL - Which do You need for your website?
With so many different types of SSL certificates, it can get difficult to keep track of the virtually unlimited variety of online security options. The web is sometimes very obtuse, and not every business has an army of security specialists helping them out. Thankfully, if you've managed to get here, then you're just one small step away from getting your very own SSL certificates for proper protection.
The only decision you need to make is whether you need a regular Multi-Domain SSL certificate, or if you should opt for a Wildcard SSL certificate, instead. We've hinted at the differences between the two over the past few sections, but let us reiterate.
Choosing between a SAN certificate and a Wildcard SSL certificate should boil down to your desired feature-set. Do you need to secure multiple domain names, or do you need access to an SSL that affords you security for unlimited subdomains on your main domain?
If your business has multiple domain names, and if you've got no SSL certificates currently in place, then you'll need to get a Multi-Domain SSL certificate. This option will allow you to cover multiple domains right off the bat.
On the other hand, if your business has a unified online presence under a single domain, but a bunch of subdomains that you want to secure as well, you'll need to get a Wildcard SSL certificate.
Of course, there is an option for business users that need both! Multi-Domain Wildcard SSL combines the two for practically unlimited protection with enhanced support mechanisms. You don't even need to give up the ease of use that comes with Multi-Domain SSL certificates.
Multi-Domain SSL Certificates FAQ
Multi-Domain SSL/TLS is a comprehensive website certification technology that binds a unique cryptographic key to the verified details of a given organization, then applies their specific certificate to multiple owned domains at once. It is often used when you have a website that might have auxiliary services attached, such as an office communications server. Or, say, for Microsoft Exchange integration.
UCC/SAN stands for Unified Communication Certificate/Subject Alternative Name. These terms are used to describe the way Multi-Domain certificates simultaneously support different domains with a single instance. They can even extend to covering unlimited subdomains if you opt for Wildcard SAN certificates.
