A wildcard SSL certificate secures a single domain like *.domain.com and its subdomains with one certificate. It provides HTTPS encryption for subdomains, triggers the green URL bar, can be installed on unlimited servers quickly, and acts as a one-stop security solution for e-commerce sites. To set it up, the certificate signing request common name must be in the format *.domain.com so it covers all subdomains of that domain.
