If you host multiple sites inside the exact same account and one of them is hacked, it is very likely that all of them will get hacked after that. There're various reasons why this could happen, the two most common are: using very weak passwords or using older scripts with widely known weaknesses. In this way, just a single compromised website can make lots of damage to all of your Internet sites, since gaining access to a single script generally allows hackers to access the web hosting account. This is the reason why we have developed a brand new security option called JailHost. Once activated, this feature will literally lock an Internet site in its folder, so if an attacker takes over it, the other websites in the account will remain hidden. Thus they'll be resistant to further intrusion. The JailHost option does not mean that you should not keep your Internet sites up to date, but it will greatly reduce the damage.
