Wildcard certificates work the same way as a regular SSL Certificate, allowing you to secure the connection between your website and your customer’s internet browser – with one major advantage: a single Wildcard SSL Certificate covers any and all of the sub-domains of your main domain. If you have multiple subdomains to secure, then a Wildcard SSL Certificate purchase can save you a lot of money and time vs the cost of buying individual SSL certificates. With one Wildcard SSL Certificate you can secure subdomains on many servers.
For example a single Wildcard certificate for *.domain.com can be used to secure:
- payments.yourdomain.com,
- login.yourdomain.com,
- mail.yourdomain.com,
- download.yourdomain.com,
- anything.yourdomain.com
