Enterprise PQC Migration Checklist

5Screenshot_2026-05-27_092406.jpg

Post-quantum cryptography (PQC) migration is a complex, enterprise-wide program that goes beyond a simple upgrade, requiring discovery, risk-based prioritization, governance and coordinated implementation across systems, vendors, and environments. Organizations must inventory cryptographic usage, assess constraints, and prioritize action based on exposure and long-term data sensitivity, while adopting crypto-agile, hybrid architectures to support a phased transition. By treating PQC as an ongoing capability and aligning stakeholders, vendors and standards, enterprises can systematically migrate, monitor and secure data-in-transit against evolving quantum threats.
