Post-Quantum Migration Guide
Preparing your critical infrastructure for the quantum era. NIST algorithms, maturity grid, roadmap and NIS2/DORA compliance.
The quantum threat is real. Migration must start now.
The RSA, ECC and Diffie-Hellman algorithms that currently protect virtually all digital communications will be vulnerable once a sufficiently powerful quantum computer arrives — estimated 2030-2035. The "harvest now, decrypt later" strategy makes the threat immediate: data intercepted today can be decrypted tomorrow.
This guide provides CISOs, security architects and infrastructure teams with a complete methodology to plan and execute the migration to post-quantum cryptography (PQC). It is based on NIST standards finalized in 2024 (ML-KEM, ML-DSA, SLH-DSA) and ANSSI recommendations for French information systems.
