Sift ATO stop rate is not Forter ATO block

How to run thisChargebacks3 steps
CalculatorSift ATO-block share · Calculator lives in the articleOpen

Divide ATO stops by auth attempts in one Sift decision cut. That ratio is stop %.

Pair: ATO-block share on Chargebacks. Forter twin: ATO-block. Abuse twin: payment-abuse.

What you type

ATO blocks — Sift account-takeover stops raised in the decision cut.

Auth attempts — Auth attempts in that same Sift decision cut.

Stop % = ATO stops ÷ auth attempts × 100. Fat stop % usually means credential-stuffing heat — retune ATO rules; never invent a stop chip.

What not to do

Skip inventing stop %. Skip dumping a Forter ATO file into Sift fields. Skip treating payment-abuse blocks as ATO stops. Skip blending MIDs when one seat owns the stop pile.

Related: Chargebacks, ATO-block, payment-abuse, auto-block overturn.

Procedure

  1. Type ATO blocks and auth attempts.
  2. Read ATO %.
  3. Retune ATO rules when ATO % is material.

Failure modes

  • Inventing ATO %.
  • Dumping a Forter ATO file into Sift fields.
  • Treating payment-abuse blocks as ATO stops.
