The Endurance of Defenders: Lessons from Ultrarunning and Cyber Resilience
Zach Tisher

Every security professional knows the grind — long hours, unpredictable conditions, and the constant push to adapt when fatigue hits. In that way, cybersecurity and ultrarunning have a lot in common. Drawing on years of experience leading security transformations at Home Depot and Equifax and competing in 50-mile and 100-mile mountain races, Zach Tisher explores how endurance thinking, shared purpose, and community can transform how we approach modern defense.
