Here's what Duo's devotees are saying
former Security Manager, Yelp
“We were incredibly blown away at how our deployment went...this was the easiest deployment we’ve ever done. I’m really impressed.”
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.”
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."
