They already do that. On WallStreet they've been doing it for years(i.e hire ex MI6/Mossad/CIA). I don't see why it wouldn't happen in other sectors.

Funny you should say that. Companies are hiring ex-Intelligence people to handle such things.

Competitive intelligence has been integral part of big companies for decades.

It's probably a good thing, security hygiene in the private sector has been laughably neglected for far too long.
