Only Nexcess clients on non-cloud clients may use the method outlined in this article to learn how to buy wildcard SSL certificate. Nexcess Cloud customers can see our reference to another related article.

If you are a Nexcess Cloud client, instead see How to purchase SSL certificates from your Client Portal. Nexcess clients on physical servers may use either method. In addition, the Nexcess product page for SSL certificates is a great place to start.

What is a wildcard SSL certificate?

When a single SSL certificate has the wildcard asterisk character (*) in the domain name field, the certificate becomes a wildcard SSL certificate. The wildcard feature allows the certificate to authenticate and provide HTTPS encryption to a website and all of the subdomains under the same base domain. If you buy a wildcard SSL certificate, you can protect the exchange of valuable information visitors send to or receive from a website's primary domain and its subdomains.

If you own and you need to encrypt your site, but you also need to make sure and are secure, a wildcard SSL certificate lets you protect all three, as well as any other subdomains you might have.

Why should you buy wildcard SSL certificate?

If you want to set up multiple subdomains under the same domain, you should consider how to buy wildcard SSL certificate. Instead of having to install multiple SSL certificates to cover each individual subdomain, you can buy wildcard SSL certificate to cover all of them.
