In case you host multiple Internet sites in the very same account and one of them gets hacked, it is likely that all of them will get hacked after that. There are several reasons why this may happen, the two most common are: using very weak passwords or using outdated scripts with widely known vulnerabilities. In this way, one single compromised Internet site can do lots of damage to all of your sites, because gaining access to one script often allows hackers to access the web hosting account. This is the reason why we've developed a top-notch security option known as JailHost. Once enabled, this feature will literally lock a site in 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 does not mean that you should not keep your sites updated, but it'll significantly limit the damage.
