Hi,
Will you please tell me which C-Panel/WHM version are you currently using?
By the way you can still lock down SSH pretty well as making the following changes simply:
vim /etc/ssh/sshd_config
PermitRootLogin no #disable root user login
Port 221 #ssh port other than the default which is 22
AllowUsers bob #only allow limited user/s
and then finally restarting the SSH daemon:
service sshd restart
