Features 8

Notable capabilities this provider offers.

Per-Merchant Machine Learning

Custom ML models trained and tuned to each merchant's traffic, products, and fraud patterns rather than a single global model.

Graph Network Analysis

Link analysis across customers, devices, payment instruments, and addresses to surface hidden fraud rings and shared-identity clusters.

Consortium Identity Database

A shared identity-signals consortium spanning 9+ billion identity elements used to enrich risk scoring across all merchants.

Real-Time Decisioning

ALLOW / REVIEW / PREVENT decisions returned synchronously on every checkout, login, registration, voucher, and transaction event.

PSP-Agnostic 3D Secure

A 3DS Server that works with any acquirer or PSP, supports dynamic exemption routing, and is bundled with native iOS and Android 3DS SDKs.

Manual Review Workflow

Built-in dashboard for human review of borderline cases with webhook callbacks to sync decisions back to the merchant's order management system.

Rules Engine

Merchant-authored rules layered on top of ML scores, executed in active or passive mode so new rules can be safely shadow-tested before going live.

Per-Customer Rate Limiting

A built-in 50 events-per-minute-per-customer guardrail that returns a PREVENT action with source RATE_LIMIT to defend against scripted abuse.
