France's ANSSI to Block Non-Quantum-Safe Products from Certification by 2027

France's Anssi Will Block PQC-Free Products from Certification Starting 2027

France's ANSSI has set a hard 2027 deadline, requiring all certified security products to include quantum-resistant encryption. This move aligns with the U.S. NSA's CNSA 2.0 timeline, creating a critical procurement gate for vendors on both sides of the Atlantic. Unlike U.S. standards, ANSSI mandates hybrid implementations combining classical and post-quantum algorithms, forcing a complex engineering shift. This policy transforms quantum readiness from a planning exercise into a binding market requirement, exposing a significant preparedness gap across European critical infrastructure.
