Red Hat addresses quantum computing threats through post-quantum cryptography (PQC) in RHEL 10 and OpenShift, embedding quantum-safe algorithms at the infrastructure layer rather than application level. U.S. federal agencies must pilot PQC by 2027 and fully implement by 2029 per Executive Order 14412, making immediate preparation critical. Organizations should inventory cryptographic assets, test new primitives in non-production environments, shift security to the platform layer, and maintain operational control over data placement—delaying action risks 3–5 year disadvantages as quantum hardware becomes available.
