Most of these things do not need to be public though. Whatever your existing setup is, you can build a box around it so that suspicious people are not allowed in. Then you only have the outer box to really worry about.

Of course if you want to enable people to make important decisions from their homes, you have two options, build a box around their homes too or accept that they are outside of the box and treat all of their activity as suspicious.
