Using out-of-date apps or templates and plugins for them, or using very simple passwords is always a risk for your sites since these things make it considerably easier hack them. Things get worse in case you have a couple of sites as all of them will be vulnerable when an attacker takes over only one of them. This is the reason why we have created JailHost - an advanced level security feature which isolates websites from each other. In the event that a site is compromised, the attacker will not be able to find or access any other content outside the website folder, so all the rest of the Internet sites part of this account will be protected and will remain intact. The JailHost option doesn't replace carrying out routine script updates or using difficult passwords, but it'll minimize any damage to your sites significantly, so you'll have to fix only one Internet site and not all of them.
