Using a Wildcard Certificate: How Does It Work?
The Wildcard SSL certificate is a unique SSL/TLS provision with a wildcard character (asterisk/*) in the domain name field. Due to this, Wildcard certificates are 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
If you see yourself using multiple subdomains in the future, investing in a Wildcard SSL Certificate today can save you money in the long run - as you wouldn't have to buy multiple certificates later on - and provide you with a comprehensive management option for all of your subdomains.
Single-domain Wildcard SSL Certificates can only secure subdomains on a single domain level. So 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. These Multi-Domain Certificates allow you to secure multiple sub-domain levels with just one Wildcard Certificate, saving you even more money.
What is the Use Case for a Wildcard SSL Certificate?
Securing any part of your site within a single domain name scope is an invaluable option for many website owners, using the sub-domains to section them off ( such as your blog or store ). Setting up a mail server, if nothing else, calls for a similar solution. Naturally, the ability to rely on a single SSL/TLS Certificate to secure every sub-domain you are currently using or plan to use is convenient.
A Wildcard certificate can secure unlimited servers and subdomains - if that's what you need it to do. For example, you may need to keep separate sandboxes for multiple services your website offers. Wildcard SSL certificates allow you to do precisely that, whereas a single domain certificate wouldn't.
There are many different kinds of SSL/TLS Certificates. A Wildcard SSL/TLS Certificate, in particular, is designed from the bottom up to be among the most versatile security solutions. Once a Certificate Authority issues you the Cert and you have it installed, it will secure the primary domain and all its subdomains.
| Secures | Unlimited Sub-domains |
|---|---|
| Warranty | Up-to $1,750,000 |
| Key Cryptography | RSA or ECC |
| Minimum Key Size | 2048-bit (RSA), 233-bit (ECC) |
| SSL/TLS Encryption | 256-bit Encryption |
How to choose the right Certificate Authority for my Wildcard SSL Certificate?
Virtually all CAs are signing Wildcard Certificates as of 2020. 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 look up specific certificate pages using the appropriate links.
The critical thing to remember is that no matter which price point you might be looking at, you're getting a security solution that will do the base job you require (securing your domain). Even the cheapest Wildcard SSL available is far better than having no SSL at all, and it's evident that websites with multiple subdomains need a more cost-effective option than a regular single-domain SSL provides.

SSLTrust were a bastion of sanity and competence during a unpleasant battle with Sectigo's processes. They went out of their way to help us get what we needed and it was great to have someone "in our corner". MUCH better than dealing direct! Kudos to Paul for his assistance.
SSLTrust provides a great service. Have used them for years. Emails get answered quickly and helpfully. Highly recommended.
Excellent and efficient customer service. We urgently required an EV codesigning certificate. SSL Trust assisted us after hours on the day we made the application (Thursday), company verification was completed the following day and the token arrived the following Wednesday. We were also provided with technical assistance with accessing the user portal and setting up the token. The experience was immeasurably more efficient than our previous experience purchasing an EV codesigning certificate from a supplier based outside of Australia.
Wildcard SSL Certificates FAQ
Once issued, a Wildcard SSL certificate will secure your main domain and your subdomains that exist as part of it. Since many websites use multiple subdomains simultaneously, Wildcard certificates are an ideal choice for many users.
The name 'Wildcard' is derived from the wildcard characters that define this particular certificate functionality. The asterisk (*) at the beginning of the secured domain, such as *.domain.com, will be a placeholder for any sub-domain.
A cheap Wildcard SSL certificate is 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. Of course, the level of support you might get will vary from one CA to another, but business validation level and the customers' security should be satisfactory.
Depending on your website's services, 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 all its subdomains. However, there may be better choices if you 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 the 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 different 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 these SSL certificates feature the same standard 256-bit encryption or more, some pricier choices also come with extra bells and whistles. Depending on your preference, expect to spend between £31.41 and £410.31 every year. From Comodo to DigiCert, there are many options to choose from.
