Payment gateway risk audits for fintech

A focused look at how we teach teams to examine gateway behavior — before a partner review writes the agenda for you.

What an audit actually inspects

Healthy uptime is not an audit. We train teams to inspect authorization-to-settlement paths, exception queues, fee integrity, webhook authenticity, and the human workflows that respond when monitors fire.

For fintechs in Korea, that often includes domestic rail quirks, multi-PSP routing, and documentation habits that satisfy both local partners and cross-border sponsors.

Our method in three movements

  • Discover

    Diagram trust boundaries and inventory logs you can actually query. Discard vanity metrics that never reach an owner.

  • Test

    Sample settlements, replay webhook edge cases, and challenge risk-score assumptions with counterexamples.

  • Narrate

    Produce findings with severity, evidence pointers, and remediation owners — short enough that executives read them.

When to bring a cohort in

Teams usually arrive 60–90 days before a PSP renewal, after a chargeback spike, or when merging stacks post-acquisition. If you only need templates, start with Signal Desk. If you need shared language across product and risk, choose Ledger Room.
