Episode notes
In the premier episode of Shielded: The Last Line of Cyber Defense , Johannes Lintzen welcomes Bas Westerbaan , Research Engineer at Cloudflare , to break down real-world post-quantum migration challenges and solutions: Cloudflare’s early PQC adoption - lessons from years of real-world implementation Why you need two migrations (encryption today, authentication next) How to secure executive buy-in & conduct a cryptographic inventory The hidden performance & compatibility challenges of PQC deployment Why vendor readiness & regulatory compliance will shape adoption Bas Westerbaan is a Research Engineer at Cloudflare, specializing in post-quantum cryptography and its practical implementation at scale. With a PhD in theoretical quantum computing from Radboud University and experience across academia and industry, including roles at UCL and PQShield, Westerbaan brings a unique perspective to the intersection of mathematical theory and real-world cryptographic engineering.
