Wildcard SSL certificates work the same way as a regular SSL Certificate, allowing you to secure the connection between your website and your customer's Internet browser – with one major advantage.
A single Socalweb Comodo Wildcard SSL Certificate covers any and all of the sub-domains of your main domain.
If you have multiple sub-domains to secure then a Wildcard SSL Certificate purchase can save you hundreds or thousands vs the cost of buying individual SSL certificates.
