What happened
The National Institute of Standards and Technology (NIST) released a detailed migration plan that recommends hybrid cryptographic deployments—using both classical and quantum‑resistant algorithms—starting in 2027. The guidance identifies four priority use cases (code signing, asymmetric user sign‑in, TLS/VPN data‑in‑transit, and email/document signing) and aligns with the OMB mandate to mitigate quantum risk by the end of 2030. Agencies may retain legacy algorithms only in a “deprecated” state after a documented risk assessment, and NIST highlights the ML‑KEM family as the primary quantum‑resistant key‑exchange mechanism, with a second KEM under review.
Why it matters for trust and compliance
- Organizations must map their cryptographic controls to the new NIST PQC roadmap, turning algorithm selection and key‑management evidence into a core component of audit readiness across frameworks.
- Map existing cryptographic controls to NIST’s hybrid migration guidance to demonstrate alignment with NIST CSF Protect and Identify functions.
- Collect continuous, defensible evidence of hybrid algorithm deployment for future audit and certification readiness.

Federal agencies Critical infrastructure operators
Recommended actions
- Inventory all public‑key assets and the algorithms they currently use.
- Pilot hybrid cryptographic solutions for the four NIST‑identified use cases.
- Update key‑management policies to include risk assessments for any deprecated algorithms.
- Implement continuous monitoring to capture evidence of algorithm usage for audit purposes.
