If you host multiple Internet sites inside the very same account and one of them is hacked, it's more than likely that all of them will be hacked after that. There're several reasons why this may happen, the two most popular are: using very weak passwords or using outdated scripts with well-known vulnerabilities. In this way, one single compromised website can make lots of damage to all your sites, because getting access to a single script often allows hackers to access the entire hosting account. This is the reason why we've developed a brand new security option called JailHost. Once activated, this option will literally lock a website within its folder, so if an attacker takes over it, all the other Internet sites in the account will be hidden. Thus they'll be protected from further intrusion. The JailHost option doesn't suggest that you should not keep your sites up to date, but it will significantly minimize the damage.
