David Deering
Founder
In an industry known primarily for dark rooms and guys in hoodies, it’s easy to think technology is the answer. But after 16 years consulting some of the world’s largest companies on cyber security, David Deering realized product was not the answer. Cyber security requires a unique hybrid of people, processes and technology. And so LEO was born. Prior to founding LEO, David was involved with three other significant startups, two that were acquired and one that went public.
David Tompkins
Founder
David is our mountaineer and growth-master. He’s been to the summit and back multiple times holding leadership and founding roles in some of the industry’s most respected cyber advisory and technology providers. His last trek was with FireEye-Mandiant as an original member of the founding team resulting in one of the biggest IPOs in InfoSec history. Following the acquisition of Mandiant, David jumped in to the real fight going behind enemy lines helping companies and governments battle through some of the greatest breaches in history.
