DigiCert® Wildcard TLS/SSL Certificates
The Wildly Simple
Way to Tame
Subdomains
You could buy a thousand certificates
to secure a thousand subdomains.
But with wildcard, all you need is one.
What is a Wildcard TLS/SSL Certificate?
Wildcard TLS/SSL certificates simplify subdomain management and reduce costs by using one certificate to secure a single domain and all related subdomains. By using the asterisk symbol (*) as a placeholder (*.example.com), a wildcard certificate will automatically secure any subdomain at the same level (e.g., mail.example.com, blog.example.com, support.example.com).
For organizations with multiple subdomains, wildcard certificates are a no-brainer—a scalable, cost-effective way to enhance website security across subdomains under a single, unified certificate.
How to Buy a DigiCert Wildcard TLS/SSL Certificate
1. Select the plan that best fits your security needs.
Choose from Secure Site Pro, Secure Site, or DigiCert Basic.
2. Choose the number of wildcard domains you want to include with your purchase.
Note: You can combine wildcard and fully qualified domains onto a single multi-domain certificate.
3. Add the certificate to your cart.
Add your wildcard certificate to your cart and complete the checkout process.
