With the Most Loved Company in Security and the global leader in network technology joining forces, there are more exciting opportunities than ever to be at the forefront of securing the cloud.
Our mission is simple: democratize security by making it easy and effective for everyone.

Together we build for the future by designing simple solutions for complex problems. And that's why we're the most loved and trusted name in security.

An Insider's view of Duo Security

How does your team reward individual success?

It can be as quick as some karma in Slack. We do team appreciations at the start of team meetings and Cisco has connected recognition which allows individuals to recognize the great work someone has done along with a monetary award, from $25 on up! We also celebrate life with team members, for example throwing a virtual baby shower!

Hector

Senior Engineering Manager

What's the biggest problem your team is solving?

Our cross-functional team of data scientists, software engineers, and designers, as well as product and security experts is building an intuitive adaptive authentication system. We’re moving past basic rule-based approaches to create a dynamic experience that people will love for keeping them secure while staying unobtrusive.

Brian

Head of Data Science and Engineering

What are some things you learned at the company?

Early on, I thought that success in the security industry was attributed solely to people's ideas or intellect. Since then, I've learned that the most important thing to have in any industry is empathy. Without empathy, you can't build a product that people will love or a place that people will want to work. Empathy is a foundation for success.

Olabode

Senior Data Scientist

What is your vision for the company?

My overall vision is to provide mechanisms for the business to build simple, safe and secure products that our customers and partners intrinsically trust. It is my belief that when we empower our teams and stakeholders to creatively work together instead of falling on process and procedure for the sake of it, our creativity opens to new heights.

Amanda

Head of Product Security

What makes someone successful on your team?

Success for us is taking the road less traveled to achieve better results, meaning we look for teammates who bring perspectives from all walks of life and who are not afraid to use their voice. We believe this combination results in good outcomes because we end up paving our path to success with a diversity of thought.
