Payments processing. Continuous PCI-DSS evidence + real-time fraud-model attestation — for the rails that move money.
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.
Four forces converging on the payment rail.
PCI v4.0, PSD3, AI-fraud audits, and an ISO 20022 migration collapse onto the same evidence requirement.
PCI-DSS v4.0 continuous controls
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.
PSD3 / PSR pressure
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.
AI-fraud-model fairness audits
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 migration + ransomware
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.
Capability mapped to QSA expectation.
PCI-mapped evidence pipeline
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.
AI-fraud-model AI-BOM
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.
Signed cryptographic-library SBOMs
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.
Vendor concentration on HSM / issuer-acquirer SaaS
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.
Frameworks the platform is mapped to.
Pre-mapped control narratives and evidence in the formats your QSA, scheme, and central-bank reviewer already accept.
A typical deployment at a regulated processor.
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.
VPC-isolated control plane in PCI scope
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.
Dedicated GPU for fraud-model attestation
Single-tenant GPU pool runs the AI-BOM generator and fraud-model drift monitor. SHA-pinned weights, attestation at install, deterministic inference latency.
Audit log streamed to processor SIEM
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.
Signed evidence portal for QSA + regulator
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.
Four risk surfaces sitting on top of every transaction.
HSM-firmware compromise
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.
Fraud-model adversarial gaming
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 message-handler vulns
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.
Ransomware on acquirer scheduling
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.
What is actually hitting payment processors this year.
- MOVEit-class file-transfer compromise in batch-settlementManaged file-transfer software underpins settlement, reconciliation, and chargeback exchange. A MOVEit-class zero-day in any of them exfiltrates cardholder, merchant, and PII data in volume.We address this through SCA + KEV prioritisation on MFT components
- HSM-firmware OEM backdoorHardware-vendor firmware introduces a flaw — accidental or otherwise — that survives every downstream PCI control. Provenance and SBOM diffing on firmware are the only signal.We address this through SBOM Studio with firmware ingest
- Fraud-model adversarial driftCoordinated actors push the model into an under-detected regime. Without AI-BOM lineage and drift monitoring, the loss curve moves before any analyst sees it.We address this through AI governance for fraud models
- ISO 20022 parser CVEsNew ISO 20022 messaging libraries ship with parser vulnerabilities the moment they hit production. Reachability tells you whether the CVE actually touches a money path.We address this through Eagle reachability on parser codepaths
- Sanctions-screening library tamperingCompromise of OFAC / EU / UN sanctions list ingestion libraries lets prohibited counterparties slip through screening. Signed provenance and continuous integrity checks block the silent regression.We address this through Comply with global regulations
