Download the Guide

As one of the most trusted and widely used resources for online business reviews, Yelp’s operations span 24 countries and counting.

In order to protect employee access to their corporate network, including engineers and executives internationally, their security team enlisted Duo Security’s two-factor authentication solution for fast and easy deployment, low costs, and high confidence in our steadfast dedication to security.

According to Yelp’s security team, they were interested in two-factor to prevent unauthorized access to their corporate network, by protecting their SSH and VPN connections. Company-wide, Yelp’s employees needed to access their internal networks for the resources and tools necessary to do their jobs - engineers, executives and a remote team in Germany all needed to securely VPN into their network. Additionally, other employees needed remote access if they worked outside of normal work hours. But with access comes the necessity to verify their identities and permissions.

Yelp chose Duo Security over competitors due to a higher level of confidence in the quality of our security solutions, according to Yelp’s Security Manager, Ivan Leichtling.
