Summary
👤
Senior🎓
Top SchoolPaul Wouters is a senior security architect with 19 years of experience designing and hardening VPN, IPsec/IKE and DNS/DNSSEC systems for enterprises and open-source ecosystems. He blends deep protocol-level cryptography and network/OS security expertise with practical operational skills—package maintenance, release management and fleet encryption—currently applied at Aiven and in the Libreswan project. A prolific standards author and IETF Security Area Director, he’s the principal author of NIST SP800-77 Rev1 and co-author of multiple RFCs, bringing rare influence across standards, open source and commercial deployments. Beyond tooling and code, he’s an experienced presenter and trainer who translates complex security policy into actionable engineering. Notably, his long-standing contributions to Openswan/Libreswan and active Fedora packaging work ensure the software he champions is production-ready at scale.
