Fraud Prevention · Pix

Anti-fraud decisions faster than Pix itself.

Identity, device, network and lists combined in a sub-second decision — with signals that only exist in Brazil: Pix, MED, SIM swap.

On Pix, fraud settles in seconds. A batch rule arrives too late.

Today
  • Pix fraud settles in seconds; a batch rule arrives late.
  • Block too much = customers call; block too little = MED and loss.
  • An imported engine doesn't know Pix, MED or Brazilian late nights.
With VAAS
  • Sub-second decision before the money leaves.
  • Branched outputs: block, step-up 2FA or approve.
  • Native signals: Pix, MED, SIM swap, payroll deduction.
Workflow builder

You compose the steps like a flow.

Each signal becomes a step that writes to the same dossier. Identity, device, network, lists and score in your policy order. No code. Versioned. Reversible in one click.

Anti-fraud at the speed of Pix.

Truly sub-second

Identity → device → network → lists → score → decision, all under one second. The legitimate customer feels nothing.

Native Brazilian signals

Pix, MED, SIM swap and payroll deduction are signals an imported bureau doesn't have. That's where Brazilian fraud happens.

  • DICT
  • MED
  • SIM swap
  • Local velocity

Branched outputs

Not just yes or no: block, step-up 2FA or approve, chosen by risk and ticket, not a single rule.

  • Blocked
  • Step-up 2FA
  • Approved

Disputes and refunds, organized

A MED pipeline with a full trail: from suspicion to refund, with evidence ready for the dispute.

Pix fraud doesn't wait. We had to decide before settlement, with signals that make sense here. VAAS delivers a sub-second block without punishing the good customer.
