A Wildcard SSL Certificate allows you to secure a primary domain and an unlimited number of its subdomains with a single certificate. For example, a Wildcard SSL for *.example.com would cover www.example.com, blog.example.com, shop.example.com, and any other subdomain.
Unlike regular SSL Certificates, which are issued for a single domain or subdomain, Wildcard SSL Certificates can secure multiple subdomains under the same primary domain, offering greater flexibility and cost savings for websites with numerous subdomains.
Yes, with a Wildcard SSL Certificate, you can add new subdomains at any time without needing to reissue the certificate. This makes it easy to expand your site as needed without additional SSL costs.
Wildcard SSL Certificates do not cover subdomains at multiple levels (e.g., sub.sub.example.com), and some Certificate Authorities (CAs) may have specific restrictions or additional validation requirements for issuing Wildcard Certificates.
