Real-time fraud screening for every transaction.
ML scoring tuned to your industry, a rules engine your team can read, chargeback defense, and sanctions screening — one system for catching fraud and staying compliant.

Everything Fraud & Risk Controls needs to ship — in the box.
Real-time transaction scoring
Every authorization scored inline against an industry-tuned ML model — fast enough that legitimate customers never feel it.
Rules engine you can read
Plain-English rule builder layered over the ML score. Test rules against historical traffic before they go live — no surprise block waves.
Device, velocity, and consortium signals
Device fingerprinting, velocity tracking, and BIG-wide consortium intelligence. Bad actors flagged across the network, not just inside your account.
Chargeback defense
Pre-built evidence packets, automated responses to representments, and direct integration with Ethoca and Verifi alerts — so you can fight the disputes worth fighting.
OFAC + sanctions screening
Every counterparty screened against OFAC, EU, and UN lists in real time. Travel Rule support for crypto, watchlist updates pushed daily.
Case management
Manual review queues, reviewer notes, and audit-grade decision logs. Built for ops teams that need to explain every block to a regulator.
Fraud + compliance, in the same workflow.
Underwriting, screening, and chargeback defense — surfaced in screens your risk team uses every day.
Underwriting that explains itself.
Every approval, decline, and conditional carries the underwriter's reasoning. Risk score, supporting docs, OFAC result — all in one card. No more black-box decisions.
- Decision rationale per app
- OFAC + sanctions checks
- Audit log per reviewer

Compliance evidence, on demand.
Every ACH origination, KYB document, and AML decision indexed and exportable. When the auditor asks 'show me', the answer is two clicks away.
- KYB doc store
- AML audit trail
- Auditor-ready exports

Manual review without slowdowns.
Suspicious transactions queue with full context — device fingerprint, prior behavior, peer-cohort benchmarks. Approve, decline, or escalate in one screen.
- Full context per case
- Peer benchmarks
- Single-screen workflow
