No-Regrets Migration: Why PKI Should Be Your First Move

Episode notes

Hardware security modules (HSMs) sit at the core of digital trust, protecting transactions, PKI systems, and authentication. As quantum computing approaches, traditional HSMs face limits that can’t be solved by patching old hardware. In this episode of Shielded: The Last Line of Cyber Defense , host Johannes Lintzen speaks with Bruno Couillard, CEO and co-founder of Crypto4a and co-creator of the Luna HSM, about building quantum-safe HSMs. Bruno explains the difference between PQC-ready and PQC-providing, warning that retrofitting classic devices is not enough. He highlights PKI as the no-regret first step and shows how hybrid models let organizations bridge classic and post-quantum algorithms. Cloud adoption and scalability challenges demand modular, cloud-aligned HSMs instead of isolated, priest-only boxes. Bruno’s message is that HSMs are the foundation of digital security, and crypto-agility is now essential for surviving the quantum era.
