I would like to secure my billing system and was thinking of having it at client.domain.com. I understand this would need a dedicated IP and a certificate installed.
I would also like to give my clients access to a secure cPanel so I could use cpanel.domain.com:2083
The certificates I am looking at are the domain certs Rapid SSL and Positive SSL
I have 3 questions:
Which SSL cert to go for?
Is it better practice to use a sub domain for the clients billing system or just use a directory?
Is shared certificate possible if so, can I use the same certificate for shared cPanel access?
I hope that all makes sense. Any pointers would be appreciated.
