An Insider's view of Duo Security

What does your typical day look like?

I always say I have a typical week, not a typical day. My work weeks are consumed by customer interactions (emails, working sessions, status calls and onsite business reviews), internal knowledge-sharing meetings and laughing with coworkers. However, each day is different and is shaped by customer needs.

Lisa

Senior Customer Success Manager

What are some things you learned at the company?

I have learned directly the value of diverse teams. Demographics, background, skills and seniority diversity blend to form higher performing teams as long as individuals are empathetic and kind to one another. Diversity allows for healthy conflict and understanding which push teams forward.
