Founded in 2010, Duo protects more than 14,000 organizations against data breach by making security easy and effective. Duo’s Trusted Access security products verify the identity of users and the health of their devices before granting them access to applications - helping prevent breach and account takeover.

Prior to its acquisition by Cisco, Duo raised $119 million in total capital, backed by Benchmark, Geodesic Capital, Google Ventures, Index Ventures, Lead Edge Capital, Meritech Capital Partners, Radar Partners, Redpoint Ventures, True Ventures and Workday. 

Dug is a renowned hacker and leading voice in the information security industry. He is often quoted on cybersecurity issues by international media, and appears onstage at industry events around the world.

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 a founding member of Ann Arbor’s a2newtech and an active participant in Tech Brewery, a2skatepark and the Entrepreneurs' Foundation of Ann Arbor.
