SSL (Secure Sockets Layer)
Secure Sockets Layer; secures an internet connection by encrypting data sent between your website and a browser or between two servers.
The Wildcard SSL Certificate is an ideal solution for entry-level websites that need to protect one main domain (both www and non-www) along with their subdomains (i.e. exampledomain.com.au, mail.exampledomain.com.au, admin.exampledomain.com.au, retail.exampledomain.com.au, etc.)
