Senior🎓
Top SchoolHidde-jan Jongsma is a senior cyber security scientist with 15 years’ experience blending rigorous research and hands-on engineering, currently focusing on Software Supply Chain Security and SBOM at TNO. He holds a PhD in Applied Mathematics and applies formal, systems-level thinking to vulnerability research, quantum-safe cryptography, and automated security tooling. As founder of Pikir and an early entrepreneur who built a web agency in his teens, he pairs product-minded development and UX with deep technical leadership in DevSecOps and end-to-end encrypted architectures. He has led multidisciplinary teams to translate complex research into practical proofs-of-concept and standards adoption, and has a particular interest in making Self-Sovereign Identity usable. Notably, his background in control theory and networked systems gives him an uncommon edge when analysing systemic supply-chain risks and attack surfaces.
