What is a Wildcard SSL certificate?
A Wildcard SSL Certificate helps enable SSL encryption on multiple sub-domains using a single certificate as long as the domains are controlled by the same organization and share the same second-level domain name. For example, a Wildcard certificate issued to Company ABC using the Common Name (“*.CompanyABC.com”) may be used to secure the following domains:
