It would be nice if the NSA had spent the last decade or two helping shore up cybersecurity, instead of creating, stockpiling, and accidentally leaking zero days to later get used in ransomware attacks.
I've thought exactly this thing for years. I'm afraid that you'd have to build a completely separate organization with a separate management line up to the top of the chart. and even then you'd spend most of your time protecting yourself from the NSA and it's brethren.
