Is Multi-cloud crypto Quantum Proof? Cyber Program & PQC
Verdict
Multi-cloud does not diversify away quantum risk if every cloud path still uses classical public-key defaults. Normalize inventory, KMS algorithms, and TLS policy across providers.
Overview
Each provider offers different PQC preview features. Program owners need a cross-cloud control matrix.
Program inventory focus: Inconsistent algorithms and policies across clouds. Typical classical surfaces: Per-cloud KMS and cert services; Cross-cloud identity federation. Cross-read /security/program and /assessment. Educational only—not compliance advice.
Cryptographic profile
- Signatures: Per-cloud KMS and cert services, Cross-cloud identity federation
- Hash: N/A
- Public-key exposure: Inconsistent algorithms and policies across clouds.
What breaks
- Three clouds, three untracked PKIs
- Federation with classical-only tokens
Mitigations
- Unified inventory tags by cloud
- Shared crypto standard
- Pilot hybrid on each major edge
