What is a Wildcard SSL certificate?

The Wildcard SSL certificate not only does everything a single-address SSL certificate does, it also protects every subdomain for any given domain. What does this mean? As an example, let’s say you assign a Wildcard SSL certificate to “*”. This certificate will apply to “”, but also to any of its subdomains, such as “”, “”, “” and so on.

How does a Wildcard SSL certificate work?

A Wildcard certificate is actually one of the easier certificates to create. All it requires is for you to generate a certificate for a domain name by using the following syntax: “*”. This Wildcard SSL certificate will then be applied to the main domain “” as well as to all of its subdomains. It’s the asterisk (*) that makes all the difference, and it is also a quick and simple way to identify a Wildcard SSL certificate. The Wildcard SSL certificate thus protects every subdomain of the chosen domain name without requiring any additional purchases or setup.

When should I use a Wildcard SSL certificate?

This type of SSL certificate provides you with many advantages. But what are the main benefits of using such a certificate?

Securing every subdomain,

As previously mentioned, the Wildcard SSL certificate helps to secure a domain name and all its subdomains. Before the Wildcard SSL certificate, you would have to get an individual SSL certificate for every new subdomain you create. Now, you can secure all your subdomains with a single certificate. How is this helpful? The Wildcard SSL certificate not only protects existing subdomains, but also future subdomains you may decide to create later on. Thus, you will never have to worry about securing new subdomains, as the Wildcard SSL certificate will include them automatically without further action.

Easier to manage,

Renewing SSL certificates can be a time-consuming endeavor. Managing an individual SSL certificate for a large number of subdomains would be very time consuming. By only having a single Wildcard SSL certificate which applies to all of your subdomains, renewing can be done a lot faster and more effectively.

A more affordable option for securing all your subdomains,

SSL certificates can get quite costly. And when a dedicated certificate is required for each of your subdomains, those expenses definitely add up!

Thus, the Wildcard SSL certificate is the go-to option when it comes to securing multiple subdomains at once. One certificate for a plethora of advantages!
