How organizations can make a successful transition to Post-Quantum Cryptography (PQC)

The document is an advisory on preparing for quantum-era threats, warning of “Harvest Now, Decrypt Later” attacks and recommending a four-step organizational program: adopt a top-down quantum-safe strategy (favoring hybrid cryptography and NIST-recommended algorithms), inventory cryptographic assets and prioritize long-lived sensitive data, implement PQC key-exchange (hybrid mode with ML-KEM), and transition to PQC digital signatures (ML-DSA) with pragmatic proxy approaches to ease deployment.
