What is a Wildcard SSL Certificate?

A wildcard SSL certificate secures your main domain and all its first-level subdomains (e.g., *.yourdomain.com).

This means one certificate protects:

• yourdomain.com
• www.yourdomain.com
• mail.yourdomain.com
• shop.yourdomain.com

Wildcard certificates are ideal if you have multiple subdomains to secure without buying individual SSL certificates for each.
