Regulatory compliance requires architecture evidence
PCI-DSS, SOC 2, and banking regulators demand documented system architecture. Manual documentation is expensive to produce and immediately outdated.
Payment system complexity is hard to map
Payment processors, banking APIs, fraud detection, KYC services, and ledger systems form a complex web. Nobody has a complete picture.
Architecture changes have compliance implications
Moving a service, changing a data flow, or adding an external integration can affect your compliance posture. Without visibility, you discover this during audits.
Audit preparation consumes engineering time
Engineers spend days or weeks preparing architecture documentation for auditors instead of building features that generate revenue.
C4 model maps the complete fintech stack
Document payment flows, banking integrations, data stores, and internal services at four levels of detail. Auditors get the views they need.
Conformance rules enforce compliance standards
Define rules that enforce PCI-DSS boundaries, data isolation requirements, and security standards. Automated checks run continuously.
Change requests create an audit trail
Every architecture change goes through a review workflow with full traceability. Show auditors who changed what, when, and why.
Drift detection catches compliance gaps
When the codebase drifts from documented architecture, you know immediately. No more discovering compliance gaps during the audit.
AI Discovery for Legacy Banking Systems
Point AI at legacy payment code and get a documented architecture automatically. Understand complex banking integrations without manual reverse-engineering.
ADRs for Compliance Decisions
Document why specific architecture decisions were made for compliance reasons. Link ADRs to C4 elements for full traceability.
Create overlays showing PII flows, payment data paths, and trust boundaries. Show auditors exactly where sensitive data moves.
DORA Metrics for Engineering Health
Track deployment frequency, lead time, and change failure rate alongside architecture health. Balance velocity with compliance.
AI Architecture Queries
Engineers query the architecture from AI assistants: 'What services handle payment data?' 'Show the PCI-DSS scope boundary.'
Compliance Alert Webhooks
Get notified when architecture changes affect compliance scope. Integrate with your compliance tooling through webhooks.
