Web host management refers to a program which lets clients enjoy administrative access to cPanel back-end. Web host management offers a high degree of control and flexibility when you must manage multiple popular and resource-rich websites. With WHM you can also create and handle many cPanels. It may be a wise decision to keep different sites on different cPanels. This is because in case any of the sites gets hacked for some reason, your other sites may not become vulnerable to hacker attacks. Your privacy is enhanced because there is no means of identifying if multiple accounts on separate cPanels are all attached to a single WHM account.
