Duo Security Triples Revenue for the Third Year in a Row

More than a Million Users Worldwide

Duo Security, a cloud-based access security provider protecting the world’s largest and fastest-growing companies, today announces over 200 percent growth in revenue in 2015 over 2014. In addition, Duo has doubled its customer base, now protecting companies and institutions such as American Public Media, Virginia Tech, Fireeye, Duke University, DraftKings, Bolton NHS Foundation Trust, Citizen’s Union Bank, Zenefits, RestorixHealth, University of York, and, the makers of Candy Crush. By the end of 2015, Duo analyzed nearly 2 million devices with 1 million users, and handled nearly 2 million authentication events per day.

In April 2015, Duo launched its Platform Edition, which builds on two-factor authentication to offer cloud security and endpoint visibility. Customers using Platform can gain insight into the security hygiene of all endpoints, including mobile and unmanaged devices, without installing any agents. This functionality helped several customers address Android Stagefright and Flash vulnerabilities exposed in 2015 and reduce the risk of data breaches. Platform ensures that users trying to access company applications and systems are who they say they are. With new functionality introduced in Duo Platform, companies can protect themselves against outdated devices and out-of-date operating systems prone to hundreds of security vulnerabilities.

To accommodate rapid customer growth, Duo opened an office in the San Francisco bay area and in London, England, securing new customers like King, the makers of Candy Crush, and Bolton NHS Foundation Trust. A survey of Duo Security customers in 2015 revealed that 98 percent would recommend Duo.

“It’s all about ease of use and keeping our customers happy,” said Dug Song, CEO and co-founder of Duo Security. “We’re passionate about continuing to be the most loved company in security. People are feeling the pain of the cumbersome security products and we’re here to make it painless for them.”
