FedRAMP High Baseline compliance has always demanded rigorous controls, but now the threat model has shifted. Quantum computing is no longer theoretical. The encryption that passed audits five years ago will fail against quantum attacks. Meeting FedRAMP High today means integrating quantum-safe cryptography into every layer of your architecture.
The National Institute of Standards and Technology (NIST) has already selected post-quantum algorithms for standardization. These lattice-based and hash-based primitives are designed to withstand the massive parallelism of quantum processors. For systems operating under FedRAMP High, upgrading to these algorithms is not optional—it is the new baseline for protecting Controlled Unclassified Information (CUI) and high-impact cloud systems.
Implementing quantum-safe cryptography under FedRAMP High Baseline requires more than swapping out libraries. You must evaluate your key management infrastructure, TLS termination, API endpoints, stored data, and backup encryption. Certificates, identity providers, and secure communications must shift to post-quantum algorithms before deadlines arrive. Waiting means increasing your attack surface every day.
Quantum-safe migration plans start with inventory. You cannot protect what you cannot see. Identify all current cryptographic dependencies. Map their algorithms and key lengths. Compare them against NIST’s post-quantum recommendations. Validate that your software dependencies and cloud providers can handle the load of newer, stronger algorithms without degrading system performance.
