Twelve executives own different aspects of integrated risk management inside the modern enterprise, from the board and the CEO down through the CISO, the CFO, and the chief compliance officer, and today's risks move too fast and cut across too many of those aspects for any one of them to work alone.

Two seats come back nearly empty. The Chief Legal Officer holds a single Primary-fit vendor across the entire field, with the widest Not Served band of any persona. The Chief Human Resources Officer holds none at all.
