Be that as it may, with regards to securing all sub-domains alongside principle domain, Wildcard SSL certificate is required. Workings of both the certificates, i.e. SSL Certificate and additionally Wildcard SSL certificate is nearly the same with just a single significant contrast and that is Wildcard SSL Certificate gives security to main domain as well as, to all other sub-domains connected to the fundamental area independent of SSL certificate, which gives security to just the main domain.

Working of Wildcard SSL Certificate

When an organization applies for Wildcard SSL Certificate, it means that it owns multiple website or sub domains.

When CA (Certification Authority) issues a certificate, organization must ensure that all sub domains are associated with the main domain else it will affect the level of security.

Once the validation of the domain and the sub domain is checked, Wildcard SSL Certificate will provide the same level of security to the main domain and all other sub domains associated with it.

Wildcard SSL Certificate will look for all the possible sub domain names and will provide security to them. For example, a Wildcard SSL Certificate is issued to *.mybusiness.com, where ‘*’ represents all the sub domains associated with the main domain and in return Wildcard SSL Certificate will provide security to all the possible sub domains suffixed ‘.mybusiness.com’.
