Routing changes, fraud threshold updates, gateway modifications alter payment behaviour in ways no team tracks.
ISO field handling drifts incrementally as patches accumulate. Truncation persists undetected for months.
A Southeast Asian bank updated a microservice routing rule. ISO 8583 field DE48 was silently truncated for ATM transactions — undetected for 11 days until a call-centre spike.
Root cause: Unvalidated interaction between a routine BAU change and a live ISO 8583 field — invisible to every tool in the stack.
Impact: Seven-figure remediation cost. Reputational damage with card network.
Always-on BAU validation surfaces which changes touch which flows — before they reach production.
Test suites are built around expected successes. Partial auths, concurrent duplicates, schema rejections are structurally absent.
Retry storms, idempotency fractures, timeout cascades — the highest-cost failure modes are almost never tested.
Manually crafted data cannot exercise real failure conditions. Masked production data creates PCI exposure.
A European processor migrated MT→MX format. Common structures mapped correctly. Edge cases in address fields and remittance data were not examined.
Root cause: Protocol migration creates thousands of new field combinations that go unexamined with general tooling.
Impact: 12% SWIFT rejection rate. Emergency remediation. Certification delay. Partner trust erosion.
WISO surfaces 95%+ more edge cases. Native ISO 8583/20022 intelligence. PCI-safe synthetic data generation.
Revenue leakage, false declines, churn accumulate continuously — yet almost no organisation has put a dollar figure on their exposure.
40% of customers who fail do not retry. They leave permanently. Silent, preventable, invisible in monitoring dashboards.
Multi-system failure diagnosis is a cross-functional fire drill — hours of log hunting compound the incident cost.
A payments platform updated fraud-scoring logic. Retry behaviour under high concurrency was not validated. Peak Saturday traffic triggered a retry storm: 4,300 duplicate authorisations.
Root cause: Retry and idempotency edge cases under concurrent load are invisible in sequential validation.
Impact: Three-week settlement disruption. Regulatory enquiry. Total cost exceeded $1.4M.
StressLab exposes retry storms before peak day. Trace compresses RCA from days to minutes.
Issuer simulators, acquirer environments, processor sandboxes — unavailable, unreliable, or not reflecting production. Pre-go-live confidence is structurally impossible.
ISO 8583→20022 migrations introduce thousands of new field combinations. Post-migration rejection rates of 10–12% are documented.
Visa, Mastercard, RTP, SWIFT certification cycles — manual, rebuilt from zero every time. One failed test case sets launch back weeks.
RTR receive capability is mandatory at go-live. Every onboarding wave is a certification deadline. Organisations arriving unprepared face regulatory exposure and missed revenue.
Root cause: Certification cycles built from scratch with no production-grade simulation of the downstream chain.
Impact: Certification delays cost weeks of regulatory exposure and revenue from new rails.
Production-grade digital twin eliminates simulation deserts. Pre-built scheme libraries. 60–70% faster certification cycles.
Generic API tool + simulator + load tester + monitoring + manual certification — five systems that don't communicate. The CFO never sees the aggregate TCO.
ISO field semantics, EMV cryptograms, DUKPT key management — concentrated in a handful of engineers. A bottleneck, a failure point, a retention risk.
Bespoke tools don't evolve with scheme rules, lack scenario breadth, and consume engineering time worth more on roadmap delivery.
A mid-tier bank ran five separate tools — none integrated. The CFO had never seen the aggregate TCO. Two engineers held all ISO and EMV knowledge. When one resigned, every certification stalled.
Root cause: Specialist dependency: institutional knowledge concentrated in one engineer.
Impact: Six-month certification backlog. Emergency recruitment. Three months to rebuild knowledge.
One platform replaces 3–4 tools. WISO makes specialist knowledge accessible to every engineer.
Test results, monitoring, incident logs, post-mortems — all in different systems. No authoritative board-ready view of payment stack health.
Without a dollar figure for unvalidated flows, reliability investment always loses the CFO conversation to QA budget framing.
Passing a PCI-DSS or MAS TRM audit is a snapshot. BAU changes the following week render that posture obsolete. Regulators expect continuous evidence.
PruTan catches the failure that exists only at the intersection of a BAU change and a payment protocol edge case — before it reaches production.
Phased RTR launch. Receive capability mandatory at go-live. PruTan validates RTR conformance and Interac/Lynx interplay.
NPP, PayTo mandates and RBA ISO 20022 migration. BECS decommissioning adds complexity.
FedNow and TCH RTP scaling alongside Nacha rules. One platform covers instant rails, ACH and ISO 8583.
EU Instant Payments: 10-second mandate and Verification of Payee. PruTan validates SEPA Instant, VoP and the UK NPA.
World's highest-volume real-time market. PruTan — trusted by NPCI — assures UPI flows at national scale.
mada, KNET, NIBSS-class switches and new instant-payment schemes. PruTan validates switch certification.
ISO 8583, ISO 20022, REST, UPI, SEPA Instant, FedNow, RTP and RTR — validated against each market's mandate from a single platform.
Built on ISO 8583 and ISO 20022 with full field-level awareness across ATM, POS, mobile, gateway and switch. Not a REST wrapper — a protocol-up build.
Trained on proprietary failure modes, BAU-change breakage patterns, and scheme certification edge cases unavailable publicly. Knows what breaks payment systems.
The entire assurance lifecycle — BAU validation, simulation, interception, load testing, observability, executive governance — in one platform.
ISO/IEC 42001:2023 and ISO/IEC 27001:2022 certified — verified by accredited third-party bodies. Trusted by NPCI. Certifications earned, not claimed.
Deploys inside CI/CD as infrastructure — integral to the release process, not alongside it. High natural switching costs and growing data advantage.
PruTan defines Payment Reliability Assurance. The planned Payment Reliability Index will make PruTan the industry measurement standard — not just a vendor.
