QNSI for Regulated Finance & Banking
PQC for retail/wholesale banking, broker-dealers, and payment processors under PCI DSS, MAS TRM, DORA, and FedRAMP equivalents.
Source-backed key-management, audit, vault, and compliance-mapping surfaces for banks, broker-dealers, and payment processors evaluating PCI DSS v4.0.1, MAS TRM, DORA, and emerging PQC obligations. Health-derived status is operational telemetry, not certification or control-effectiveness proof.
Threat model
What we're defending against
The HNDL, regulatory, and operational threats specific to this vertical.
Harvest-now, decrypt-later on long-life records
Transaction records, KYC files, and customer correspondence are retained for 7-30+ years. Anything captured in transit today becomes exposed if a cryptographically relevant quantum computer arrives. No authoritative arrival date exists; NIST transition guidance removes quantum-vulnerable algorithms by 2035, with high-risk systems moving earlier.
Cross-border data movement under conflicting regimes
A Singapore bank operating in the EU and US faces MAS TRM + GDPR + DORA + PCI DSS simultaneously. Snapshot-style annual audits leave gaps; regulators increasingly demand continuous evidence.
Vendor-key concentration risk
When one cloud KMS holds keys for KYC, settlement, and SWIFT messaging, a single compromise blast-radiuses every downstream regulator filing. Per-tenant cryptographic isolation contains the blast radius.
Compliance mapping
Frameworks this vertical operates under
QNSI supports continuous evaluation for 7 live frameworks; other named frameworks are architecturally supported with evidence available on request.
| Framework | How QNSI maps |
|---|---|
| PCI DSS v4.0.1 ↗ | Section 3 (Protect Account Data) maps to QNSI vault + crypto-policy enforcement; Section 10 (Log and Monitor) maps to audit-service immutable chains. |
| MAS TRM (Singapore) ↗ | Cryptographic Controls and Audit Logging sections require key-lifecycle evidence and tamper-evident logs - both produced by QNSI audit-service. |
| DORA (EU financial) | ICT third-party risk and incident-reporting obligations: QNSI exports continuous evidence packs; multi-region failover is provisioned per tenant on enterprise engagement. |
| ISO/IEC 27001:2022 ↗ | A.8 (Asset management) and A.10 (Cryptography) anchored on QNSI crypto-inventory (CBOM) and crypto-policy-enforcement. |
| SOC 2 Type II ↗ | Common Criteria CC6 (Logical Access) and CC7 (System Operations) - RBAC, tenant isolation, real-time control evaluation. |
QNSI architecture
Capabilities mapped to this vertical
How QNSI services compose to meet this vertical's needs.
ML-KEM-768/1024 + ML-DSA-65/87 for transaction signing, rotation automation, BYOH HSM support
Versioned secret-storage and retention contracts with a PQC-envelope migration target; end-to-end execution remains NOT VERIFIED
Source-defined Merkle aggregation and ML-DSA checkpoint signing; complete event ingestion and verification remain deployment-specific
Strict tier locks the bank to FIPS-finalized algorithms only; per-tenant policy
Continuous inventory of every cryptographic asset across the estate - including legacy RSA/ECDSA
Outcomes
What deploying QNSI for this vertical delivers
- ✓Strict crypto-policy tier - every signing operation uses ML-DSA-65 or stronger, every KEM uses ML-KEM-768 or stronger
- ✓Tamper-evident audit chain that survives regulator review without bespoke evidence assembly
- ✓Per-tenant isolation across business lines (retail / commercial / wealth) - single compromise does not cascade
- ✓Continuous compliance evidence (PCI DSS, SOC 2, ISO 27001, MAS TRM) - not annual snapshots
