In case you host multiple Internet sites in the very same account and one of them gets hacked, it's more than likely that all of them will get hacked afterwards. There are different reasons why this could happen, the two most popular are: using very weak passwords or using older scripts with well-known vulnerabilities. In this way, just a single compromised Internet site can make lots of damage to all of your Internet sites, because getting access to a single script often allows hackers to access the hosting account. This is the reason why we've developed an outstanding security option called JailHost. Once enabled, this feature will literally lock a site inside its folder, so if an attacker takes over it, the other Internet sites in the account will be hidden. Thus they'll be protected from further intrusion. The JailHost option does not mean that you should not keep your websites up-to-date, but it'll significantly limit the damage.
