Quite an interesting article! I am curious as to how this "limited collection" of IR firms adds to or drains from the overall security ecosystem. On one hand, having a limited number of firms allows for seamless knowledge transfer, and upholds a somewhat high standard of service - kind of like a licensing regime. On the other hand, I wonder if this cartel limits innovation and keeps new entrants with new ideas and better service from entering the fray. Maybe its a bit of both?
