When An Architecture Review Makes Sense
Common fintech moments when a threat-led review saves time, cost, and surprises
You don’t need a full-time security team to know when something feels off in your stack. An architecture review is usually worth it when one or more of these are true:
-
You’re scaling CNP payments and flows feel fuzzy. -
PCI DSS or SOC 2 are coming and scope is unclear.
-
Banks or partners keep asking tough security questions.
-
Incidents or near-misses shook confidence in controls.
-
Monolith is splitting to APIs and auth feels risky.
-
Multi-cloud or multi-env; no single up-to-date diagram.
-
Expanding to new regions with stricter data rules.
-
Leadership wants a clear, risk-ranked security view.
What We Review
Across Apps, Data, Vendors & Controls From APIs to cloud to vendors, we find weak links before they scale
Apps & APIs
- Login, account, checkout, payouts, admin.
- Identity flows, session handling, device/browser signals.
Data & Infrastructure
- Card, PII and secrets flows.
- Cloud accounts, networks, storage, queues, CI/CD.
Vendors & Third Parties
- PSPs, fraud/KYC vendors, CRMs, data platforms.
- Who can move money or see sensitive data.
Controls & Evidence
- Logging, alerting, approvals, and change management.
- How today’s setup maps to PCI DSS, SOC 2, ISO 27001.
How An Architecture Review Works
From first diagrams to audit-ready evidence in four focused steps
01 Discovery & Diagrams
We start with your product goals, incidents, and constraints.
Diagrams, configs, and data flows are captured in one picture.
02 Threat Mapping
We turn those diagrams into CNP and API threat scenarios.
Abuse cases and compliance gaps are flagged with clear impact.
03 Control Design
We design practical patterns for auth, tokens, keys, and network zones.
Controls are shaped to fit how your teams actually build and ship.
04 Roadmap & Evidence
Findings become a prioritised backlog with quick wins and owners.
You leave with audit-ready docs, diagrams, and an evidence checklist.
What You Get
A single, reusable package your engineers, leaders and auditors can share
Every review ships with
- System context & data-flow diagrams your team can reuse.
- Threat model with risk-ranked issues and clear owners.
- Recommended patterns for auth, secrets, logs & monitoring.
- PCI / SOC 2 control mapping for everything we’ve reviewed.
Your Internal Source of Truth
Most clients turn this pack into their internal “source of truth” for:
- Audits and vendor due-diligence
- Onboarding new engineers and security hires
- Future redesigns of apps, APIs and cloud environments
