The key difference between those technologies and this is that industrial production hardware (centrifuges or specialized biological equipment, etc) are needed in addition to specialized knowledge of the topic at hand. These additional requirements make export controls a lot more enforceable, and why you can, say, send regulators to the site of a nuclear engineering facility and get a reasonable answer about if they have sent nuclear materials to another country.
With infosec this would be basically impossible, since the specialized knowledge and the equipment are both non-physical and intimately entwined.
