• SSH access with shared hosting plans

Ans: We do NOT provide direct root ssh access with our shared web hosting plans but we can provide Jailshell access. 
Jailshell is a very limited shell that allows clients to login to the server via SSH. 
It limits the clients to their home directories, keeping the rest of the files on the server from being viewed.
