22. Mark McLaughlin, Palo Alto Networks
As the hottest company in the next generation firewall space -- really, the network security space -- Palo Alto Networks' long search for a new CEO was a closely watched process in Silicon Valley. Finally, the company confirmed in August 2011 that it had its man: Mark McLaughlin, the former CEO of VeriSign and a longtime security veteran. In an interview with CRN at Palo Alto's partner conference in New Orleans in November, McLaughlin kept the message simple: his goal is to keep Palo Alto chugging along, and maintain the channel focus that's endeared it to so many security and infrastructure focused VARs.
