I know private security is very well developed in Guatemala: every serious bank, jewelry store, mall has it. Private roads are probably not allowed, but I actually met a wealthy woman whose family founded the first intercity bus company in Guatemala in the 1920s and she told me how her great grandfather helped to build the roads.

I'm guessing they don't allow any competing forms of governance, though: i.e. privatized roads with their own enforcement or private communities with their own rules and security forces.
