CISA published federal guidance directing agencies to procure only post-quantum cryptography-capable products in technology categories where quantum-resistant solutions are widely available. The guidance responds to a 2025 executive order and identifies product categories split into two lists: those with broadly available PQC implementations (cloud services, browsers, endpoint security) and those still transitioning (networking hardware, SaaS platforms, telecommunications). The directive aligns federal procurement with NIST-standardized algorithms designed to protect against future quantum computer attacks that could break current encryption systems. Products must support quantum-resistant key establishment and digital signatures, with CISA planning regular updates as more categories mature.
