The best thing about zada is that it's fully managed so you don't have to worry if your VPS goes down or gets hacked because they are doing all of this work behind the scenes! I think there should be an option where users can set up their own firewall rules in addition to having them do everything automatically like with other companies out here (like AWS). We use our server as part of one website hosted by another provider but we wanted some extra security measures put into place since we were hosting sensitive data such as bank account numbers etc..
