Watched video by this name the other night (Julia Roberts, Clive Owen). It's about industrial espionage (not CI!) involving two packaged goods companies - my old stomping ground. While I have heard a lot of exotic tales, some true and some not over the years, this movie just doesn't make a lot of sense. Yes, I realize I should have left LEFT BRAIN at the door.
1) CI can never afford this degree of investment by either company. Nor is it required.
2) CEO's are not that delusional, but certainly well-advised as per the movie to keep the secret amongst the fewest number of people. (e.g. the Coke formula)
3) Lack of due diligence on the stolen "baldness cure" IP doesn't do justice to CI professionals.
4) There are generally much simpler, cheaper ways to get the information. Misrepresentation not required.
All that said, I can completely vouch first hand for the complete transparency similar companies are at risk of in terms of what competition knows about them. How's your information security environment?
I once challenged a well-qualified 3rd party, one readily available to any and all of us, to penetrate my organization without getting apprehended. They did, they got absolutely everything - fast.
