The San Francisco startup survived a year-long shipping stumble by making the router feel less like equipment and more like an appliance. A decade later, its real product is not the white box - it is fewer reasons to think about Wi-Fi.
Bastille Networks is a San Francisco-based cybersecurity company that secures the wireless airspace - the radio frequency spectrum inside corporate and government facilities that traditional network security tools never see. Using patented software-defined radio and machine learning, Bastille passively detects, identifies, and locates every cellular, Bluetooth, Wi-Fi, and IoT device in a building, including rogue phones and devices not connected to the network. The company serves Fortune 100 firms, financial institutions, and the U.S. intelligence community, and raised a $44M Series C led by Goldman Sachs Asset Management in January 2024.
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.
