High security is not “maximum security”, and chasing perfect security is a security hazard. More security can always be purchased at a greater cost of money and time. But some of the most involved systems we have seen involve dozens of hours of tedious and error-prone effort to set up. With overly complex systems, there is a danger that users will give up or get lazy momentarily, leaving them less secure. And with added complexity there is increased danger of user error leading to catastrophic loss.
