Enterprise Post‑Quantum Cryptography Migration Faces Governance Gaps and Massive Scope
What Happened — A panel of cryptography and governance experts warned that moving to quantum‑safe encryption is an enterprise‑wide transformation. 120 k+ tasks were logged in one program, with only a quarter touching cryptography directly; the rest involve inventory, vendor management, regulatory reporting, and upskilling.
Why It Matters for Compliance & Audit Readiness
- SOC 2 control families for Change Management, Vendor Management, and Key Management must now include quantum‑safe requirements, otherwise evidence gaps appear during audits.
- Continuous evidence collection on PQC readiness provides a defensible audit trail that demonstrates “reasonable security” under the Trust Services Criteria.
- Mapping PQC controls to SOC 2 criteria helps prove due‑diligence to regulators and customers, reducing the risk of future non‑compliance findings.
Who Is Affected – Large enterprises across technology, finance, healthcare, and cloud‑service providers that rely on public‑key encryption for data‑in‑transit and data‑at‑rest.
Recommended Actions –
- Extend your SOC 2 control matrix to include PQC algorithms and key‑lifecycle processes.
- Incorporate PQC readiness checks into vendor risk assessments and procurement workflows.
- Capture continuous evidence (e.g., inventory scans, policy updates, training records) to satisfy audit evidence requirements.

Technical Notes – The migration challenge stems from the impending ability of quantum computers to break RSA/ECC. No specific CVE is cited; the risk is a systemic cryptographic weakness that will become exploitable once sufficiently powerful quantum hardware exists. Organizations must plan for algorithm transition, key‑generation updates, and cross‑vendor coordination.
