Duo became the link we needed to make our security philosophy really work. We now know that if folks were downloading reports or manipulating data in a cloud application, that they were doing it from a safe device, and that their identity had been confirmed with MFA.

Founded in 2010 by Dug Song and Jon Oberheide, Duo Security began as a secure access company focused on multi-factor authentication (MFA) that was dedicated to being kinder than necessary and building for the future. We expanded beyond our Ann Arbor, Michigan, beginnings in 2015 to meet the increased, international need of over 2,000 customers. No matter how much we grew, we never stopped placing customer experience and customer trust first, expanding our data security offerings beyond MFA with tools that were easy, effective and enduring.
Cisco acquired Duo Security in 2018, helping us reach over 40,000 customers in over 100 countries as part of the Cisco Secure suite of products!
