Our Investors

Duo Security is proud to be backed by an illustrious roster of investors who believe in our product, our vision, and our team.

Our Seal, Our Principles

The two stars represent the two founders of Duo Security — Dug and Jon — two outstanding members, contributors and leaders of the information security community.

The two trees symbolize our company’s roots in Ann Arbor, Michigan; a healthy mix of the city and nature, and the complementary character of a well planned human environment.

The zeros and ones are binary code for D-U-O. Binary is the digital representation of text and data in computing and telecommunication.

The shield represents the dedication and strength of Duo Security’s processes, people and technology. Our patented technology is designed to protect against credential-stealing attacks.

The two crossed keys represent the strength and design of Duo Security’s two-factor authentication solution, and the two layers of security we offer to our community and customers.

And finally, “Tuebor” is Latin for ‘I Will Defend’. This represents Duo’s mission to protect organizations of all sizes. It also happens to be derived from the Michigan state flag.
