SSL Certificates & Malware Scan - GeoTrust True Business ID Wildcard SSL
The GeoTrust True BusinessID Wildcard SSL certificate. Now you can secure your main domain, we'll pretend it's called www.your-domain.com, plus your mail server, mail.your-domain.com, maybe a members' area, members.your-domain.com, your FTP access, ftp.your-domain.com and any other sub-domains you may have associated with your site–all for one price, all with one certificate to manage.
To activate the GeoTrust Wildcard SSL functionality, all you have to do is use an asterisk in the common name when creating your Certificate Signing Request (CSR), like so; *.your-domain.com instead of using just your-domain.com.
