An SSL certificate is tied to the server and qualified domain name (FQDN) of the website. You will therefore need one certificate per FQDN that you are looking to secure. If the certificate’s common name and the FQDN on your website do not correspond, users get an error message.

Many companies have structured their website in a way so that they have one main domain like e.g. and a lot of subdomains like e.g., and Each subdomain requires a separate certificate.

A Wildcard Certificate is an SSL certificate enabling you to secure an unlimited number of subdomains and servers with one certificate. You are therefore be able to secure e.g., and with one Wildcard Certificate issued to *, what not only saves you money, but also saves you time for ordering, installing and administrating the certificates.

With Secorio’s Wildcard Certificate you can secure an unlimited number of subdomains. For a small fee, you can use the certificate on several servers.
