Why don’t folks just get a metal security door. I know they aren’t pretty, but I have one (even in CV). And it perfect when you open the door to strangers, they can’t possibly kick the thing down.
Second, I find a nice 1 inch think solid cylinder wood bar cut to length is an excellent window and door stop, that allows you to keep the doors/windows with a crack open to let in the cool fresh air, but makes it nearly impossible for someone to break in without shattering the glass.
Third, you can always put a shatter resistant film on windows so that someone that does smash a window takes more effort
