How Wildcard SSL Certificates Secure Multiple Subdomains

In this article we will talk about Wildcard SSL Certificate. SSL certificate safeguards data from a third party by ensuring secure link/connection between a server and a browser. But, when it comes to securing all sub-domains along with main domain, Wildcard SSL certificate is needed. Workings of both the certificates, i.e. SSL Certificate as well as Wildcard SSL certificate is almost the same with only one major difference and that is Wildcard SSL Certificate not only provides security to main domain but also, to all other sub-domains linked to the main domain irrespective of SSL certificate, which provides security to only the main domain.

Difference between SSL Certificate and Wildcard SSL Certificate:

Wildcard SSL Certificate secures the URL of your site and in addition its sub-domain, which can be various. Give us a chance to accept that you claim a site www .mybusiness.com. On the off chance that you get a Wildcard SSL Certificate, for this specific website, at that point it won't just secure this specific URL yet in addition, all other sub-areas like blog .mybusiness.com, shop .mybusiness.com, onlinestore .mybusiness.com and so forth., furnished these sub-spaces are connected with the fundamental space. While, a standard SSL Certificates ordinarily secures single completely qualified area name.

To put it plainly, on the off chance that you claim or deal with various destinations/pages that exist on a similar domain/ main domain, Wildcard SSL Certificate is the thing that you requirement for an entire web security and at a superior cost.

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’.
