France to halt certification of non-quantum products by 2027

France's national cybersecurity agency announced on Thursday that it will stop certifying security products that do not incorporate quantum-resistant encryption, a move set to take effect in 2027. The decision, which aligns with a similar U.S. government timeline, is expected to accelerate the adoption of post-quantum cryptography across critical infrastructure and government systems.

The announcement was made by ANSSI chief of staff Samih Souissi at the France Quantum 2026 Summit. Souissi stated that the agency will halt certifications for products lacking quantum-resistant features starting in 2027 and advised businesses to prioritize purchasing only quantum-safe products by 2030. He framed the transition as a strategic issue spanning governance, industrial planning, regulation, and sovereignty, not merely a technical challenge.

ANSSI certification is a prerequisite for security products used by French government agencies and operators of vital national infrastructure. Consequently, vendors seeking public sector contracts will need to demonstrate post-quantum cryptographic capabilities by 2027 or risk being excluded from the certification pipeline.
