There are plenty of Wildcard SSL options, but here are the top brands to choose from.

A Wildcard SSL Certificate is an incredibly versatile option for securing your web presence. With Wildcards, the name of the game is Sub-Domains. As in, a Wildcard can secure an unlimited number of Sub-Domains on just a single certificate.

So, what’s a Sub-Domain?

Let’s start with a brief lesson on URLs. When you enter the address of a website, there are several components to it. Let’s take a look at an example URL:


In this very basic example, there are only three components. The “https://” is the protocol. There are, for all intents and purposes right now, two protocols to remember. The first is http, which stands for “Hypertext Transfer Protocol.” This is the protocol that the internet is built on, a web server sends hypertext to a web browser which uses the information it receives to recreate a website as it is intended in the browser window. It’s actually a bit more complicated than that, but we’re getting distracted so we’ll leave it there. The second protocol, https, is just a secured version of http wherein all communication between servers and browsers is encrypted.

Get it? Got it? Good.

Now let’s get to the relevant stuff. In the example URL above, the “.com” portion is the TLD or “Top-Level Domain.” There are a number of these, the most common being: .com, .org, .edu. These are at the highest level of the domain hierarchy and help with organization.

The “example” portion of the above URL is the Main Domain. This is the portion most people think of first when they’re talking about a specific website.

Now, a Sub-Domain is a smaller domain that’s a part of the larger main domain. Some examples of Sub-Domains would be:

  • mail.example.com
  • login.example.com
  • ftp.example.com
  • members.example.com
  • blog.example.com

You’ve probably seen Sub-Domains countless times, you just may or may not have realized that’s what it was. The Sub-Domain always appears directly before the Main Domain, with a period separating them. Technically even “www” is a Sub-Domain, though most SSL Certificates will cover both the “www” and “non-www” versions of websites for free.

So How Does a Wildcard SSL Work?

A Wildcard SSL is a specific type of SSL Certificate that can secure a single Main Domain and an unlimited number of Sub-Domains. In order to do this, you use an asterisk in place of the Sub-Domain during the CSR generation process.

So for our example, you would enter, “*.example.com” when generating your CSR.

After that, the Certificate Authority you’re purchasing from will go through the process of issuing your certificate, and once you have installed it, it will cover all of your existing Sub-Domains—as many as you have, there is no limit.

There are lots of advantages to a Wildcard SSL Certificate and really only one drawback. The drawback is that you cannot get an Extended Validation Wildcard SSL. If you want the green address bar on your Sub-Domains you’ll have to secure them all individually using either a Multi-Domain SSL Certificate or individual single-site ones.

But, business validation is still available—you can get an Organization Validated Wildcard SSL, which will still display your business details.

Beyond that though, there are a great deal more advantages. For one, cost. Rather than securing each individual Sub-Domain with its own Certificate or SAN SSL, you’re securing them all on one certificate for a single low price.

There’s also a convenience factor. Were you to go the individual route, you would have to purchase, generate CSRs, go through validation, receive, install and configure multiple certificates. Then, when they expired you’d have to keep track of multiple renewal dates in order to continue keeping everything secure. That’s a headache. A Wildcard SSL Certificate alleviates that headache. All of your Sub-Domains and you Main Domain go on a single certificate and you’re only doing everything once.

Best of all, Wildcard Certificates are future-proof. If you ever add a Sub-Domain, just re-issue the Certificate and you’re immediately covered.

So What Certificate Authority is Best?

Certificate Authorities are the organizations that validate businesses and then issue them their security certificates. In order to become a trusted CA, you have to follow a set of agreed-upon guidelines that have been mandated by the CA/B Forum—a collection of CAs and Browsers that meet regularly to regulate the industry.

CAs vary in size and scope. Some are more regional and tend to focus on certain areas of the world, others are intent upon offering broader access to encryption and thus offer free low-level certificates to anyone who wants them, and then there are your major players—the ones who are internationally known and trusted.
