Our Mission is to Protect Your Mission.

You have your own mission to fulfill - and managing security shouldn’t stand in your way. Put your passion into your business, and trust the experts at Duo to secure it.

We Now Live in the Era of Access.

Now more than ever, employees are working from different locations, using personal devices to remotely log into your applications. As a result, we don’t know who’s accessing what, and how. It’s time to rethink security.

Duo Builds Security for People.

In this new world, people-centric security is the only effective security. That’s why we designed our security solution to work with your technology, people and their devices.
