Fraud Intelligence for Marketplaces

Connect both sides of the transaction.

By Michael Joseph · Last updated: October 23, 2026

Fraud guidance for your workflow

A marketplace depends on trust between participants who may be new to one another. Buyer and seller onboarding, listings, messages, payments and disputes can each reveal a different part of a harmful journey. IFD helps teams decide which additional signals could make that journey easier to assess.

Review relationships, not isolated profiles

Compare account connections with the action being attempted. The same detail appearing on several profiles can reflect a legitimate business or coordinated misuse. Preserve the distinction between a link, a suspicious pattern and a confirmed policy violation.

Four areas to connect

A marketplace review becomes more useful when the team can follow both accounts, their connections, and the sequence of events.

  • Buyer Context: Review access and purchase history
  • Seller Context: Assess onboarding and activity
  • Connections: Investigate repeated account links
  • Outcomes: Use disputes to inform review
