Processors, card networks, and acquirers run on a stack that is simultaneously under PCI-DSS v4.0, PSD3 / PSR, SWIFT CSP, and an ISO 20022 migration. Every dependency touches a regulated control. Safeguard turns that into a live, queryable evidence pipeline instead of a quarterly spreadsheet cycle.
PCI v4.0, PSD3, AI-fraud audits, and an ISO 20022 migration collapse onto the same evidence requirement.
v4.0 retires the annual-snapshot model. Controls have to be evidenced continuously, with measurable assurance every quarter. Pull-a-report-in-March no longer holds up against a v4.0 QSA.
The EU is moving from PSD2 to PSD3 and the new PSR. Strong customer authentication, open-API security, and continuous third-party reporting all tighten in parallel — every dependency becomes audit-relevant.
Regulators now expect fraud-scoring models to be explainable, monitored for drift, and free of disparate-impact patterns. An undocumented training set or a missing AI-BOM is a finding waiting to happen.
ISO 20022 message parsers introduce new attack surface at the same time ransomware actors are systematically targeting processor and acquirer infrastructure. Two destabilising events arrived in the same window.
Every build emits CycloneDX SBOM, signed provenance, and control narratives mapped to PCI-DSS v4.0 requirements. QSAs query the evidence store directly instead of waiting on screenshots.
Each fraud-scoring model ships with an AI-BOM: training data lineage, feature pipeline, drift metrics, and explainability hooks. Fairness audits become a query, not a six-week project.
OpenSSL, BoringSSL, libsodium, and HSM client libraries are all SBOM-tracked and signed at every release. Crypto-agility decisions go from emergency rewrites to a guided upgrade path.
Concentration risk across HSM vendors, issuer SaaS, acquirer scheduling, and tokenisation providers is exposed at the component level — not the vendor level — so procurement sees blast radius before signing.
Pre-mapped control narratives and evidence in the formats your QSA, scheme, and central-bank reviewer already accept.
VPC-isolated control plane inside PCI scope, single-tenant GPU for fraud-model AI-BOM, audit log streamed to processor SIEM, and a signed evidence portal for QSA and PSD3 review.
Control plane and inference cluster live inside the processor's PCI-CDE-adjacent VPC. No cross-tenant traffic, no shared HSM access, no shared logs.
Single-tenant GPU pool runs the AI-BOM generator and fraud-model drift monitor. SHA-pinned weights, attestation at install, deterministic inference latency.
Every fraud decision, every SBOM emit, every HSM firmware check streams a signed event in JSON and CycloneDX to the processor's SIEM — under their retention policy.
Read-only portal exposes signed SBOMs, VEX, PCI control narratives, and AI-BOM history to the QSA, PSD3 reviewer, and SWIFT CSP assessor — no email attachments.
Hardware security modules sit at the trust boundary for every PIN, token, and key-management operation. A compromised firmware image — vendor-side or supply-chain side — invalidates every downstream control without warning.
Sophisticated actors probe fraud-scoring models and learn their decision boundaries. Without continuous drift monitoring and AI-BOM evidence, the model degrades silently while losses migrate to the channels the model under-weights.
ISO 20022 introduces new parsers across the whole processor stack. Every parser is a new attack surface for malformed-message attacks, especially at the migration boundary where legacy and 20022 messages co-exist.
Threat actors increasingly target batch-settlement and acquirer scheduling infrastructure. Disruption there does not just lose data — it stops cash flow for thousands of merchants until restoration completes.
Numbers from production deployments at processors, card networks, and acquirers.
