Who we are
Dug Song is Co-founder and General Manager of Duo Security, one of the fastest-growing cybersecurity providers in the world. In 2018, Duo was acquired by Cisco for $2.35 billion, making it the largest exit ever for a Michigan-based software company.
Founded in 2010, Duo protects more than 18,000 organizations against data breach by making security easy and effective. Duo’s Zero Trust 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.
Based in Ann Arbor, Michigan, Duo has more than 800 employees with offices in Austin, Texas; Detroit, London and San Francisco. 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 co-founder of the Ann Arbor’s Entrepreneurs Fund, which enables local entrepreneurs to turn business success into positive community impact. Dug is also a board member of Ann Arbor-based security startup Censys, a founding member of a2newtech and an active participant in Tech Brewery, a2skatepark and the Entrepreneurs’ Foundation of Ann Arbor.
Dug is an executive board member of the University of Michigan’s Wallace House journalism fellowship program. He earned his bachelor’s degree in computer science from UofM.
Businesses are made stronger by the communities that support them – and we hope that with A2EF’s help, every founder can grow a culture of community engagement, service, and giving for their organization.
