9. Mark McLaughlin
Chairman, President, CEO
Palo Alto Networks
Mark McLaughlin is one of the most underrated CEOs in the business. The level-headed software subscription sales champion -- teaming with security whiz kid Nir Zuk -- has kept Palo Alto Networks on track, delivering 50 percent sales growth rates quarter after quarter. McLaughlin's real genius may well be his ability to keep the company executing even as the sales numbers get bigger and bigger and the security threats get more severe.
