Here's what Duo's devotees are saying
Mark Rodrigue
Senior Network Engineer,
Room & Board
"Our rollout was surprisingly quick,” exclaims Mark Rodrigue, Senior Network Engineer at Room & Board. "The Duo rollout took maybe four weeks from start to finish. All the training and onboarding material was right there. We just downloaded it, added our banner, and sent it to our users."
Mike Johnson
former CISO,
Lyft
"One of those rare solutions that both improves the security of our company while simultaneously being easier for our employees to use.”
Christopher Martin
Manager of Identity and Access Security, AmeriGas
"When we roll a technology out to users, we want to enable as much self-service as possible – not generate more help desk calls. This actually enables users – for example, they get a new phone and can easily get it enrolled."
