PinnacleOne ExecBrief | Post-Quantum Cryptography and Enterprise Risks

This brief outlines NIST’s August 14, 2024 release of three post-quantum cryptography standards (FIPS 203 ML-KEM, FIPS 204 ML-DSA, FIPS 205 SLH-DSA), associated federal mandates under the Quantum Computing Cybersecurity Preparedness Act, and the strategic risk posed by collect now, decrypt later. It highlights industry progress (e.g., Google, Cloudflare, IETF), technical and operational migration challenges, and provides prioritized recommendations for CISOs, including cryptographic inventories, phased PQC migration plans, crypto agility, vendor engagement, workforce training, and regulatory monitoring, noting significant cost and long timelines for full transition.
