In the end the UN isn't a good place to claim initial funding from, or if they're even a party to it. What little they get is from voluntary payments by their member states, and across all functions they have to budget (currently) for five and a half billion dollars. This goes to just about everything they run, with the exception of UNICEF and their international food programs. They don't have anything that'd make a significant impact to, or start international R+D firms.

By contrast, the US military budget is six hundred-sixty four billion dollars, funding everything involving the maintenance of our armed forces, oversees costs, and subsidies for defense technology budget by the many numbers of defense firms operating in the US. And I don't think they often share the same company with anyone for very many projects.

And private company security, in-so-far as I know is shifting more to software focus and hacker defense. Gone now are the days the CEO of Hershey's can pass himself off as a normal person and get himself employed as guy on the factory floor to learn how his competitors are making chocolates. It's more likely that if they're going to contracted for corporate security there might be a larger anti-hacker emphasis and to watch, direct, and track data traffic in the company network to seal holes in firewalls should they arise.
