Sectigo Wildcard SSL (formerly Comodo Wildcard SSL) certificate saves you time and money by securing your main domain and its subdomains with just one SSL certificate. Wildcard SSL Certificates work in the same way as standard SSL certificates, allowing a secure connection between the server and the web browser – except that with one Wildcard SSL certificate you can secure an unlimited number of subdomains, the domain for which the Wildcard SSL certificate was generated.
For example, a single Wildcard SSL certificate generated for *.mydomain.com can be used to protect:
If you want to protect multiple subdomains with an SSL certificate, Sectigo Wildcard SSL certificate can save you hundreds of dollars in terms of having to purchase separate SSL certificates for each subdomain. Additionally, managing a single SSL certificate is more convenient than keeping track of the expiration dates of multiple SSL certificates. There is no limit for servers or IP addresses on which it can be installed.
