LEO is a Cyber-as-a-Service Firm

We are a business comprised of seasoned, creative practitioners who have the lengthy experience & operational knowledge needed to architect, build, and operate cyber programs for our customers.


In an industry known primarily for dark rooms and guys in hoodies, it’s easy to think technology is the answer. But after nearly two decades consulting some of the world’s largest companies on Cyber Security, David realized product was not the answer. Effective cyber security programs require a customized approach focused on people first, process second followed by technology at the appropriate price and time. And so LEO was born. Prior to founding LEO, David was involved with three other startups, two that were acquired, IronPort and OpenDNS, and one that went public.


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 into the real fight going behind enemy lines helping companies and governments battle through some of the greatest breaches in history.
