What is Wildcard SSL Certificate? (User Guide)

How does the Wildcard SSL Certificate work?

Wildcard SSL certificate considers asterisk to add unlimited subdomains under the main domain.

In the future, if a business wants to add more subdomains, it can be covered under a single wildcard SSL cert that requires no reissuance while adding an extra subdomain in the hierarchy.

Suppose you are running a business and requires subdomains security then; you can go with a wildcard SSL certificates that works as shown below:

For example, your primary domain is *.yourbusiness.com.

  • blog.youbusiness.com
  • mail.yourbusiness.com
  • payment.yourbusiness.com

If you wish to secure mail.mywebsite.yourbusiness.com under *.yourbusiness.com, which will not be possible as a wildcard SSL certificate only secures the first level of subdomains.

For mail.mywebsite.yourbusiness.com, you need to purchase another wildcard SSL for *.mywebsite.yourbusiness.com

If you have not a budget constraint, you can also go with a multi-domain wildcard SSL.

Why use Wildcard SSL Certificate?

Wildcard SSL certificate is a boon for those enterprises who need subdomains security but at a budget price. If you purchase a single separate certificate for each subdomain, it would be a costly deal for a business.

Instead of a single purchase, a company can think about an SSL Wildcard certificate that is ideal for unlimited subdomains’ security.

Moreover, there is no reissuance necessary when you add an extra subdomain under the main domain.
