Founded in 2010, Duo protects more than 25,000 organizations globally against data breach by making security easy and effective.

Prior to launching Duo, Dug spent seven years as founding Chief Security Architect at Arbor Networks, protecting 80 percent of the world’s Internet service providers, and helping to grow the company to $120M+ annual revenue before its acquisition by Danaher. He also built the first commercial network anomaly detection system, acquired by Check Point Software Technologies. Dug is heavily involved in mentorship and fostering entrepreneurship in Michigan. He is co-founder of the Ann Arbor’s Entrepreneurs Fund, which enables local entrepreneurs to turn business success into positive community impact.
