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/* or question mark/?) in the domain name field. Due to this, Wildcard certificates can be used to secure multiple sub-domains simultaneously.

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


If you see yourself making use of multiple subdomain features in the future, invest in a Wildcard SSL certificate today. Doing so will 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.

Keep in mind that Wildcard SSL certificates can only secure subdomains on a single domain level. 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 with just one Wildcard certificate without additional costs.

What is the Use Case for a Wildcard SSL Certificate?

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. A Wildcard SSL certificate, 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 Certificate?

Virtually all CAs are signing Wildcard certificates 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 Wildcard certificates featured on this site and choose the subject that matters the most for your specific use case. Or contact our helpful and knowledgable support team to get expert help!

I was utterly and totally confused, even buying the wrong type of SSL Certificate that I needed. Trying to work out the intricacies of Wildcard SSL for 3 Servers has been a two week adventure into an area of Domain security that I have never had to venture into in the past.Spending money with our registrar for SSL certs was the wrong way to go first up.Once I found SSL Trust, purchasing and setting up SSL was easy, I just didn't know enough about Sub domains and wildcards to get the right one.Emailing SSL Trust to gain assistance and clarity on what I needed on a Friday evening and having the best support and advice come back within the hour was quite simply, refreshing and unexpected. A bit of back and forth between Paul and myself sorted out any questions I had and gave me the instructions to get exactly what I needed - outstanding!Paul organised for the incorrect SSL to be cancelled and credited which was a nice bonus and helped me feel better that I hadn't wasted money on the wrong certificate unlike the registrar who can't cancel or credit.I won't be doing a lot of SSL Certificates in the future but I have found the one company that I will use when I need to, SSL Trust!

Code Signing certificates are supposed to be hard to obtain, but with the great help and expertise of the SSLTrust team we were able to navigate the process successfully. Our company presented unusual problems for the process which had caused an attempt with another provider to fail miserably afetr several months. SSLTrust stepped into the breach and guided us through to a successful outcome. There communication was clear, their website easy to navigate, and their integration with CA providers was seamless. We would highly recommend.

We have ordered an code signing certificate from SSLTrust. Validation was a bit tricky in our case (because of reasons not related to SSLTrust), so had to contact support. The service was exceptional and just a local phone call away. We first spoke to Paul - an experienced and knowledgeable person, who was very helpful and friendly. He then followed up with emails and kept an eye on our case, in timely manner. With Paul's help we managed to get this accomplished and get our certificate. I recommend SSLTrust for all Australian customers and will certainly use their service again.

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.

The name 'Wildcard' is derived from the two wildcard characters that define this particular certificate. These are, respectively, the question mark(?) and the asterisk (*).

Each of the two main Wildcard characters serves a slightly different purpose. Between square brackets, the question mark (?) represents a single sub-domain instance. The asterisk(*), on the other hand, represents multiple sub-domains when you put it between square brackets.

By having the nature of your server setup defined using one or more characters, you can substantially streamline your SSL certificate management simply by choosing the right SSL for the job.

A cheap Wildcard SSL certificate is every bit as secure as any other SSL certificate. Wildcard certificates 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 multiple subdomains. Most importantly, there's no need to spend money on additional certificate purchases when using a Wildcard certificate. Even if you continue adding additional subdomains to your server later on, Wildcard certificates 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 €36.32 and €474.42 every year. From Comodo to DigiCert, there's a lot of options to choose from.
