RapidSSL does one thing, and it does it well: rapid-issuance DV SSL Certificates. Whether you’re looking to secure a single site or you need wildcard functionality–RapidSSL has a lightning-fast security solution that will fit easily into your budget.
RapidSSL® Automatically Secures Your Root Domain Name
When you choose to secure www in your domain name, the root domain will also be secured. Your fully qualified domain name should consist of three levels to utilize this feature. For example, domain.co.ke and www.domain.co.ke would qualify to have their root domain secured.
For example, if we receive an order for www.domain.co.ke, both www.domain.co.ke and domain.co.ke will be secured and included as values in the SAN fields of the issued SSL Certificate.
