About

In over 20 years in product management, I've spent the last 5 years+ leading the rapid expansion of the Zero Trust Exchange cybersecurity portfolio and achieved more than $200M annual recurring revenue in my directly owned products. I've also got a wider platform responsibility that has focused on scaling secure access service edge (SASE), the use of AI and ML for better platform security efficacy, and building zero trust solutions which has unlocked 26% year-over-year growth.
