I cannot imagine that there is no market for seriously secure hardware, be it laptops, smartphones, tablets, whathaveyou.
Who supplies to the military, the alphabet soups, high ranking politicians?
Im sure they use hardware with features like
>hardware killswitches for antennas, microphones, cameras
>magnetic shielding
>very good IP ratings or milspec
and the list probably goes on.
So, are these manufacturers simply not open to the public market like the arms industry? Do they produce or modify the hardware themselves?
