If you host multiple sites in the same account and one of them is hacked, it's more than likely that all of them will get hacked after that. There are different reasons why this could happen, the two most common are: using really weak passwords or using out-of-date scripts with widely known vulnerabilities. That way, a single compromised website will do a lot of damage to all your Internet sites, as gaining access to a single script generally allows hackers to access the entire hosting account. This is the reason why we have created a brand new security option called JailHost. Once activated, this option will literally lock a site inside its folder, so if an attacker takes over it, the other sites in the account will be hidden. Thus they will be shielded from further intrusion. The JailHost option doesn't imply that you should not keep your Internet sites up to date, but it will greatly minimize the damage.
