  • Dave DeWalt on how to get a board to buy in on cybersecurity

    Dave DeWalt on how to get a board to buy in on cybersecurity
    Aug 21 2025
    In this episode of Safe Mode, host Greg Otto talks with Dave DeWalt, founder and CEO of NightDragon, about advising boards and portfolio companies on making cyber a first-order business issue, not an afterthought. We’ll explore how emerging technologies and remote work reshape risk profiles, when a CISO belongs in the board conversation—or even in a board seat—and what training and metrics actually move the needle across non-technical teams. We’ll also unpack how to motivate leaders outside of IT to own cyber risk, the structures that drive enterprise-wide accountability, and what information boards should demand to ensure the right risks are being prioritized. From calibrating cyber risk appetite in shifting threat environments to staying ahead of evolving regulations across sectors like power and aviation, we’ll get practical on governance and disclosure. In our reporter chat, Greg talks with Derek Johnson about the president’s possible push to end mail-in voting, and why the efforts are dead on arrival.
