Signal Stack Selection (Onboarding)

Signal Stack Selection (Onboarding)

1. 01

   Map the client's loss events before evaluating any signal provider

   Pull 90 days of chargebacks, refund reasons, account-takeover tickets, and bot-driven signup volume. A fraud stack is only worth its price against a named loss category, not a general sense that fraud exists.

2. 02

   Separate device-layer needs from identity-layer needs

   Device fingerprinting answers whether two sessions are the same machine. Email, phone, and IP intelligence answers whether the person behind it is real. Most e-commerce clients need both; most B2B lead-gen clients need only the second.

3. 03

   Run a two-vendor overlap test on 30 days of historical traffic

   Score the same traffic through Fingerprint and IPQS in parallel, then compare flag rates on transactions the client already confirmed as fraudulent. Vendors that agree on confirmed fraud and disagree on clean traffic are the ones worth keeping.

4. 04

   Document the spoofing and traffic-shift exposure in writing

   State plainly that accuracy degrades when traffic mix changes or when attackers rotate infrastructure. Put a review date in the client file rather than implying the score stays stable forever.

5. 05

   Confirm data residency and consent posture against the client's privacy policy

   Device and behavioral signals touch personal data in most jurisdictions. Check that the vendor's retention window and processing region match what the client has already told its customers.

6. 06

   Price the layer against recovered margin, not against seat count

   Express the annual cost as a percentage of the chargeback and abuse losses it targets. A retainer add-on that costs 15 percent of documented losses is an easy renewal conversation.

7. 07

   Define the escalation path before go-live

   Name who reviews a high-risk flag, within what window, and what the client's team does with a false positive. A score with no owner becomes noise within a month.
