Securing your site is one of the most important things you can do as a website owner. If you want to see any success and protect your users from harm, you need to take the time to secure every single aspect of it. But it may seem a bit more complicated if you don’t just have a straightforward single website. That’s why in this article, we’re going to focus on how to secure multiple subdomains. And the main answer to that is with a Wildcard certificate SSL.
Read on to find out more.
First, let’s explore why someone would want multiple subdomains in the first place. Put simply, subdomains are an alternative way of dividing up your site. If you run a website called example.com, your subdomains are linked to the primary domain, example.com. And they might look something like:
There are so many reasons to have a subdomain. Maybe you want to test a sandbox version of your site that isn’t accessible to the general public. Perhaps you want to provide versions of your site in a different language or maybe a store.
But why not just add new pages to your site, you wonder? Why go to the trouble of creating subdomains? Instead of subdirectories on your website, subdomains are actually seen as different websites by search engines like Google. So a subdomain is a good idea if you don’t want your new e-commerce store messing up your SEO stats for your main website.

Whatever your website situation, SSL certificates are a key element of web security, and major tech companies have come to expect that all websites are SSL-secure. So much so that web browsers have started flagging websites without SSL as “not secure”.
But what’s the big deal? That would be encryption. An SSL encrypts the connection of anyone visiting your site. This means it hides sensitive information transmitted over the link from malicious actors. And with a Wildcard SSL, you can do this for every single one of your subdomains.
How a Wildcard SSL works
The same as every other SSL type, a Wildcard works by installing it on the server where your primary domain and subdomains live. The difference between a Wildcard SSL and, for example, a multi-domain SSL is that you’ll only have to install it once, even if you create new subdomains later. A Wildcard SSL secures all your new subdomains automatically, and the number of subdomains it will secure is unlimited. So it’s a convenient option if you aren’t sure what your website situation will look like a few months down the road. It’s also much more convenient and affordable than securing each subdomain with an individual SSL. This way, you only have to keep track of renewing one certificate instead of several.
Well, there you have it. If you’ve been wondering how to secure multiple subdomains, look no further than a Wildcard SSL certificate.
