Using a Wildcard Certificate: How Does It Work?

Multiple Secure Websites Wildcard

The Wildcard SSL certificate is a unique SSL/TLS provision that features a so-called wildcard character (asterisk/*) in the domain name field. Due to this, Wildcard certificates can be used to secure multiple sub-domains simultaneously.

A single Wildcard certificate for *.domain.com could, for example, secure any combination of the following:

  • www.domain.com
  • mail.domain.com
  • store.domain.com
  • subdomain.domain.com

And so on. Depending on your specific website, you could make ample use of just one certificate of this type. Most other types of SSL/TLS offers don't afford such a level of versatility, though multi-domain Wildcard certificates do exist, and provide users even more options for future expansion.

If you see yourself making use of multiple subdomain features in the future, investing in a Wildcard SSL could be the way to go. Doing so would not only save you money in the long run -as you wouldn't have to buy multiple certificates later on - but also provide you with a comprehensive management option for all of your subdomains.

It's important to note that - as we suggested above - only specific Wildcard certificates cover multiple domains simultaneously. For the most part, a generic Wildcard SSL certificate will be limited to a single domain with support for unlimited subdomains.

Keep in mind that Wildcard SSL certificates can only secure subdomains on a single level of a domain. If you need to safe-keep multiple levels of subdomains, you'll need to get a Multi-Domain Wildcard SSL or a Business SSL under GeoTrust, Thawte or DigiCert. As Business Wildcard SSL Certificates under GeoTrust, Thawte or DigiCert allow you to secure multiple sub-domain levels under the one wildcard without additional costs.

What makes Wildcard SSL Certificates important?

Being able to secure any given sub-domain within a single domain name is an invaluable option for many website owners. Setting up a mail server, if nothing else, calls for a similar solution. Naturally, the ability to rely on a single SSL certificate to secure every single sub-domain you may or may not have comes in extremely handy.

A Wildcard certificate can also secure multiple servers - if that's what you need it to do. As an example, you may need to keep separate sandboxes for multiple services that your website offers. Wildcard SSL certificates allow you to do precisely that, whereas a baseline DV or OV certificate wouldn't.

There are many different kinds of certificates. Wildcard, in particular, is designed from the bottom-up to be among the most versatile security solutions of its type. As soon as a Certificate Authority issues and you install a Wildcard Certificate, it will secure the main domain and all subdomains: an unlimited number of them.

How to choose the right Certificate Authority for my Wildcard SSL?

Virtually all CAs are signing Wildcards as of 2021. From Comodo to DigiCert - there's a wide variety of price options on the market, and you can always contact our team here at SSLTrust for more information. Alternatively, you can also look up specific certificate pages using the appropriate links.

The important bit to keep in mind, though, is that no matter which price-point you might be looking at, you're getting a security solution of some sort. Even the cheapest WIldcard SSL available is far better than having no SSL at all, and it's plainly obvious that websites with multiple subdomains need a more cost-effective option than a regular DV SSL provides.

Search through the SSLs featured on this site and choose the subject that matters the most for your specific use case. Or contact our helpful and very knowledgable support team to have them help you select the correct solution to your needs.

Wildcard SSL Certificates FAQ

Once issued, a Wildcard SSL certificate will secure your main domain and unlimited subdomains that exist as part of it. Since many websites make good use of multiple subdomains simultaneously, this makes Wildcard certificates an ideal choice for many users.

A Wildcard SSL certificate is every bit as secure as any other SSL certificate. Wildcards feature industry-standard 256-bit encryption (or greater) and high assurance of security coverage from the issuing CA. The level of support you might get will vary from one CA to another, of course, but business validation and the customers' security should not be a concern.

Depending on the services your website offers, you may or may not need a Wildcard SSL certificate. It's the perfect choice for those who need to quickly and easily apply a digital certificate to a domain and to all its subdomains. It may not be the best choice if you only have a main domain and a single subdomain you need to secure.

A single-domain SSL certificate differs from Wildcard SSL certificates in the scope of application, for the most part. Wildcard certificates feature the asterisk/* modifier which lets them apply to an unlimited number of subdomains, while a single-domain SSL will do no such thing.

Wildcard SSL certificates apply 256-bit encryption (or greater) to a website and an unlimited number of its subdomains. Most importantly, there's no need to spend money on additional certificate purchases when using a Wildcard. Even if you continue adding additional subdomains to your server later on, Wildcards will continue to provide security.

The price of a Wildcard SSL varies depending on which CA you decide to turn to. While all of these SSL certificates feature the same standard 256-bit encryption, some of the pricier choices come with extra bells and whistles, too. Depending on your choice, expect to spend between $37.99 and $496.20 every year. From Comodo to DigiCert, there's a lot of options to choose from.
