I am a cybersecurity expert who works with organizations to modernize their security programs. Best known as lead on the Security Chaos Engineering book and a pioneer of the discipline, I help organizations of all sizes around the world improve their security strategy to deliver real value and support growth through a sociotechnological transformation of their systems — their people, processes, tech, and architecture.

I am a Senior Principal at Fastly, working on the future of cybersecurity, and a former founder with a successful exit. I am also a member of ACM Queue's Editorial Board. In a previous life, I was a B2B product leader and investment banker and now advise high-growth startups on their product strategy. I have published several research papers in peer-reviewed academic journals and have been featured for my expertise in the Wall Street Journal, Business Insider, BBC News, ComputerWorld, TechCrunch, and other top global technology publications.

When I'm not working on bringing cybersecurity into the modern age of software engineering, I also blog; you can see my latest essays here.
