Chris Risley
Chris Risley is the CEO of Bastille Networks, the wireless threat intelligence company that uses software-defined radio to spot the cell phones, Bluetooth gadgets, and rogue radios that traditional cybersecurity tools never see. A serial chief executive with more than 25 years in software, he has run nine venture-backed startups, taken one public, and sold four to companies like Symantec, F5, and LivePerson. Before Bastille he ran DNS pioneer Nominum and DDoS-defense firm Defense.Net. He works out of Santa Cruz, California, and frames wireless airspace as the security perimeter most enterprises forgot to defend.
