Using obsolete apps or templates and plugins for them, or using very simple passwords is always dangerous for your Internet sites since these things make it considerably easier hack them. Things get worse when you have a couple of Internet sites as all of them will be vulnerable if an attacker gets control of just one of them. Because of this we've created JailHost - an advanced level security option that isolates websites from each other. If an Internet site is compromised, its attacker will not be able to see or gain access to any other content outside the site folder, so all the rest of the sites hosted within this account will be protected and will remain intact. Using the JailHost option will never substitute doing frequent script updates or using proper passwords, but it'll minimize the damage to your sites significantly, so you'll have to fix only one website not all of them.
