Platform/Fraud

04 · Fraud

Rules-first.
Explainable by design.

A centralized, rule-driven fraud engine that evaluates payment events in real time using predefined rules, enriched context, and deterministic outcomes — then orchestrates prevention actions across gateway and switch flows.

Outcomes

One policy surface

CNP and CP decisions driven from the same versioned ruleset.

Defensible outcomes

Reason codes and traces for disputes and regulatory questions.

Controlled change

Maker-checker and staged rollout for anything customer-impacting.

How it works

01
Ingest event

Authorization, auth advice, or gateway session signals.

02
Enrich

Velocity, lists, BIN/MCC, geo, device, and custom attributes.

03
Score / decide

Deterministic rules with explicit outcomes.

04
Orchestrate

Step-up, decline, or allow with downstream hooks.

05
Review

Analyst queues with full trace to rule versions.

Security & operations

  • Segregation of duties for rule authors vs approvers
  • Immutable audit for promotions and overrides
  • Data minimization hooks for sensitive attributes

FAQ

Is this a black-box score?

No. The product direction is explainable, rule-first decisions with traceability.

Can we run shadow rules?

Yes. Shadow mode is part of the rollout vocabulary.

Does it replace our case management tool?

It focuses on decisioning and evidence export; CM tools can sit beside it.
