Bret Hartman has been in cybersecurity since he was a young Air Force lieutenant. Followed by stints at the NSA, IBM, and EMC. Along the way he’s seen the focus of security shift from hardware to cloud and on to machine learning and AI. 

But Hartman, who is vice president and CTO of Cisco’s security business group, never lost sight of the importance of human creativity and collaboration in security — as new innovations arise from hackers and defenders alike. 

In a free-ranging podcast interview with Kevin Delaney — senior writer for Cisco’s Strategy and Storytelling team — Hartman shares some of his warnings, predictions, and, above all, best practices for cybersecurity in 2020. Along with insights into the innovative products and solutions in Cisco’s portfolio.
