Banks Face Quantum‑Readiness Gap: Lack of Cryptographic Inventory Threatens SOC 2 Compliance
What Happened — Recent breakthroughs in quantum error correction (Google’s Willow chip) and new research showing that fewer than one million qubits could break RSA have accelerated the timeline for quantum‑ready encryption. NIST’s post‑quantum standards (ML‑KEM, ML‑DSA, SLH‑DSA) are now final, with deprecation of RSA‑2048/ECDSA‑P‑256 slated for 2030‑2035. Regulators (e.g., CERT‑In) are already demanding cryptographic bill‑of‑materials (CBOM) from BFSI firms, yet most banks cannot precisely inventory where cryptography lives in their environments.
Why It Matters for Compliance & Audit Readiness
- SOC 2 requires documented evidence that cryptographic controls are identified, classified, and monitored; a missing inventory creates a control‑mapping gap.
- Continuous‑compliance programs need real‑time CBOM data to prove due diligence during audits and to satisfy emerging regulator‑driven quantum‑readiness requirements.
- The ability to map cryptographic assets to specific Trust Services Criteria (Security, Confidentiality) becomes audit evidence for future “post‑quantum” controls.
Who Is Affected — Banks, credit unions, and fintech platforms (financial services sector).
Recommended Actions
- Initiate a Cryptographic Bill‑of‑Materials (CBOM) project to catalog algorithms, libraries, certificates, and key lifecycles across all environments.
- Align the CBOM with SOC 2 control mappings (CC6.1, CC6.2) and integrate it into your continuous‑compliance evidence collection pipeline.
- Track NIST post‑quantum standard adoption dates and update key‑management policies accordingly.
- Conduct a gap analysis against upcoming regulator guidelines (e.g., CERT‑In QBOM requirements) and prioritize remediation.

Technical Notes — Google’s Willow chip demonstrated sub‑threshold error correction with 105 superconducting qubits, disproving the “error‑multiplies‑with‑scale” myth. Subsequent papers (2025‑2026) reduced the qubit budget for breaking RSA‑2048 to <1 M and for newer lattice‑based schemes to <100 k. NIST’s final post‑quantum suite (ML‑KEM, ML‑DSA, SLH‑DSA) will replace RSA/ECDSA after 2030; deprecation is mandatory after 2035. CERT‑In’s QBOM guidelines (v2.0) now list cryptographic elements as required fields for Indian BFSI firms. Source: same as above
