If you host multiple websites in the very same account and one of them gets hacked, it's more than likely that all of them will get hacked after that. There're different reasons why this could happen, the two most common are: using very weak passwords or using out-of-date scripts with widely known weaknesses. That way, a single compromised Internet site can make a lot of damage to all your Internet sites, since getting access to a single script often allows hackers to access the whole hosting account. This is the reason why we have created an outstanding security option known as JailHost. Once turned on, this option will literally lock a site within its folder, so if an attacker takes over it, the other Internet sites in the account will remain hidden. Thus they will be shielded from further intrusion. The JailHost option doesn't imply that you should not keep your sites updated, but it will greatly reduce the damage.
