Is PQC questionnaire Quantum Proof? Cyber Program & PQC

Risk: medium · Confidence: high · Reviewed: 2026-07-19

Verdict

A PQC questionnaire is an evidence request, not a certificate of quantum safety. Score answers by specificity: algorithms, RFCs, versions, and pilot customers beat adjectives.

Overview

Sample question themes: TLS hybrid support, certificate algorithms, token signing, code signing, firmware update crypto, client compatibility, and deprecation of classical-only modes.

Use with procurement and security architecture—not only GRC checkbox tools.

Program inventory focus: Unverified answers create false assurance. Typical classical surfaces: Requested: algorithms, hybrid modes, cert profiles, HSM support. Cross-read /security/program and /assessment. Educational only—not compliance advice.

Cryptographic profile

Signatures: Requested: algorithms, hybrid modes, cert profiles, HSM support
Hash: Response evidence links
Public-key exposure: Unverified answers create false assurance.

What breaks

Yes/no only forms
Accepting “AES-256” as full answer for handshakes

Mitigations

Require algorithm names and versions
Ask for negative space: what is not PQ yet
Retest annually
