Deep Dive Series

Getting Started With Quantum Security & PQC Migration

Post-quantum migration is not a patch cycle. It is the largest, most complex cryptographic overhaul most organizations will ever face — touching every system, every vendor, every protocol, and every assumption about how digital trust actually works. The challenge is not picking an algorithm. It is building the program: securing the mandate, finding the cryptography, documenting it, prioritizing what matters, and then migrating without breaking the business.

This Deep Dive series is a practitioner’s roadmap for that journey — organized along the lifecycle most teams actually follow. From boardroom business cases and budget justification, through cryptographic discovery and CBOM construction, to hybrid pilots, infrastructure hardening, and vendor governance, each phase links to detailed, opinionated guidance drawn from real-world PQC migration programs. The articles are designed to be read in sequence as laid out in the companion guide, or dipped into individually wherever your organization is today.

Applied Quantum PQC Migration Framework

The articles in this Deep Dive series provided the foundation for the Applied Quantum PQC Migration Framework — an open-access, practitioner-grounded methodology I developed from real PQC migration programs. It distills the lessons from these articles into a complete 8-phase lifecycle: from securing executive mandate and building cryptographic inventories through CBOM documentation, risk-prioritized roadmaps, hybrid pilots, infrastructure modernization, vendor governance, and sustained crypto-agility.

The framework includes sector-specific extensions for financial services, telecommunications, OT and critical national infrastructure, and government and defense — each adapting the universal methodology to the constraints, regulations, and legacy architectures of that sector.

    Getting Started With Quantum Security and PQC Migration

    Your complete roadmap to quantum-proofing your organization — from boardroom mandate to operational crypto-agility. This practitioner-curated Deep Dive series collects the PostQuantum.com articles you need to launch and run a quantum-readiness program, organized along the lifecycle most teams actually follow: securing executive buy-in and budget, performing cryptographic discovery and inventory, building a Cryptographic Bill of Materials (CBOM), scoring and prioritizing risk, standing up governance and a realistic multi-year roadmap, running hybrid and PQC pilots, hardening infrastructure for post-quantum performance impacts, and managing vendors and supply chains through the transition. Whether you're a CISO building a business case, a program manager calibrating scale, or a technical lead planning your first pilot, each phase links to detailed, opinionated guidance drawn from real-world PQC migration programs. Start with the comprehensive step-by-step guide at the top, then drill into the phase-by-phase articles that match where your organization is today. This is a living resource — updated as standards, tooling, and lessons learned evolve.
