Once you logged in any machine using SSH root then you can perform execution in the remote system using various commands. Most important advantage of using SSH access is that its highly secure as compare to other methods like rlogin or telnet. For some reason if the network is prone to insecurity, still SSG protocol will ensures secure data transmission using encryption. You have added advantage of session compression if you are using SSH root access. One of the most important benefit of SSH in root access is of prevention of IP spoofing.  Hacking of password by mediator hosts can be prevented if all data transaction is carried out through SSH thus SSH is highly secure and reliable.

You can easily neglect IP addresses from your network which are not trust worthy.
Thus you can prevent webmaster who act as mediators and try to hack and spoof your precious data. Such kind of violations are not possible if you are using SSH root access.
SSH always complete authentication processes before entering into a network to access any remote system.  It uses public/private key cryptographic methods for the same nad ensure the identity of the user requesting the access. Thus there is no chance that a user can spoof as another user and login to the remote systems.
SSH requires many configuration files so that it can work effectively.  It caches the host names with which it usually interact. Thus it have a list of the host names which are referred frequently this helps to make the authentication process faster. Thus root SSH ensure high level of security and all users are benefited from accessing the remote system in secure manner. you need to check if your webhosting service provider offers you SSH access.
