Brian Harrell - Top Cybersecurity Leaders 2026
"Geopolitical and cyber convergence is real. Geopolitical developments will very likely influence the cyber threat landscape in 2026 and beyond. We can't just monitor our own systems and stay compliant with the latest compliance standards. This can have significant impact to you, your supply chain, and your interdependencies. Security is local but it's also worldwide."
"I have been fortunate to serve the American people multiple times, and that's a real honor, but I am most proud of my time working to keep private-sector critical infrastructure secure. Government plays a small role, but the men and women working to keep the power grid, drinking water, and key transportation systems secure go to battle every day to keep these systems reliable and secure."
Brian Harrell, a 25-year security industry veteran, emphasizes that cybersecurity threats continuously evolve alongside geopolitical dynamics and emerging technologies. Security leaders must remain vigilant about White House initiatives and global conflicts, as these developments significantly impact organizational systems, supply chains, and interdependencies. Harrell's career spans both public and private sectors, including roles at Duke Energy, CISA, and DHS. He transitioned from traditional antiterrorism work to addressing digital threats against infrastructure. Harrell highlights that while government plays a supporting role, private-sector professionals bear primary responsibility for securing critical infrastructure including power grids, water systems, and transportation networks.
