We hear you! In this article, we’ll help you resolve one of the most common dilemmas people face while selecting an SSL certificate: SSL certificate vs Wildcard SSL. We have also covered the FAQs too. In addition, we have included discounted prices, validation level, warranties and technical compatibility of both the SSL certificates.  

How a Wildcard SSL Certificate Differs from a Regular SSL Certificate  

Standard SSL Certificates 

A regular SSL certificate, which is also known as a single-domain SSL certificate or a standard SSL certificate, secures one primary domain — both the WWW and the non-WWW versions of it. Of course, all internal webpages are covered under this regular SSL. For example:,,, 

However, a standard SSL certificate doesn’t cover any subdomains. Examples of first-level subdomains for include,,, etc. They’re considered separate domains for encryption purposes. A regular, single-domain SSL certificate won’t cover these subdomains.  

Historically, you had to buy separate single domain certificates to secure each of these subdomains individually. To aid this scenario, the certificate authorities (CAs) brought wildcard SSL certificates to the market.   

Wildcard SSL Certificates 

A wildcard SSL secures your primary domain and all subdomains that exist on a single level of your websiteA wildcard SSL secures one primary domain and all of its first-level subdomains under the same SSL certificate. 

This means that if you own, a wildcard SSL certificate will secure all the first-level subdomains such as,,,, etc. As such, you don’t need to buy separate SSL for each subdomain because they can be covered under a single wildcard SSL certificate. 

Another major benefit of using a wildcard SSL certificate is that you have to go through the certificate signing request (CSR) generation, verification, and installation process only once instead of doing all these processes for each subdomain individually.

Frequently Asked Questions (FAQs) 

Where Can I Get an EV Wildcard? 

Extended validation (EV) is not available for wildcard SSLs. To secure your subdomains with EV SSL, you either need to buy separate single domain EV SSL certificates for each of the subdomains or buy an EV multi domain SSL certificate. To learn more, check out our latest article: Can I get an EV wildcard SSL? 

Is There Any Hidden Cost for Adding More Subdomains Under a Wildcard? 

No. RapidSSL allows you to cover UNLIMITED first-level subdomains under its wildcard SSL certificates. You don’t need to pay anything extra for adding any number of subdomains so long as they’re on the same subdomain level. Plus, you can add subdomains anytime you want. No hidden costs.  

What is the Difference in the CSR Generation Process for a Single Domain SSL and Wildcard? 

During the CSR generation process for a single domain SSL certificate, enter the fully qualified domain name (FQDN), which is your primary domain (e.g.,, in the Domains field.  

To generate a CSR for a wildcard SSL certificate, add an asterisk in front of the FQDN (* A word of caution: Don’t write * before the www version of the domain like * unless you want to secure the second level of subdomains such as,, etc., which is quite an unusual practice. 

Can I Secure the Second Level of a Subdomain with a Wildcard SSL? 

Yes! But to secure the second level of subdomains (*, you need to buy a separate wildcard SSL for your first level of the subdomains. For example, to secure or, you need to get a wildcard for  

In other words, a wildcard for * can’t secure its second level subdomains. For that, you need to buy a new wildcard for the first level subdomain * 

How Much Warranty is Provided with a Wildcard SSL?
