France's cybersecurity agency, ANSSI, said it will stop certifying security products that lack post-quantum or quantum-resistant encryption beginning in 2027. Because ANSSI certification is required for products used by French government agencies and critical infrastructure operators, the policy will effectively force a phaseout of older encryption technologies across those sectors.
ANSSI official Samih Souissi said the move is intended to accelerate France's transition to quantum-safe cryptography as concerns grow over future attacks against current encryption standards. The agency also signaled a broader market shift by urging businesses to prioritize purchasing quantum-safe products by 2030, extending pressure beyond the public sector and regulated operators.
