What is a wildcard certificate?
Posted by Administrator Support on 26 June 2015 04:22 AM

A wildcard certificate can secure an unlimited number of first level sub domains on a single domain name. For example, you could get a wildcard certificate with *.yourdomain.com as the common name. This certificate would secure www.yourdomain.com, mail.yourdomain.com, secure.yourdomain.com, anything.yourdomain.com, etc... In other words, it will work on any sub-domain that replaces the wildcard character (*).
