TRUST & SECURITY / INTRODUCTION

Marketplace Fraud Prevention Basics

Look at the wider journey without treating every unusual event as proof.

Accounts and transactions are connected

Risk can appear around access, participant behavior, and changes to transaction details. Looking at those signals together can help a team decide what deserves review.

Verification is not a guarantee

A completed check is one piece of context. Clear permissions, careful authentication, and an appropriate investigation process remain important throughout an account’s lifecycle.

Use data deliberately

Collect the information needed for a defined purpose and restrict access to it. Unusual activity should lead to proportionate review, not an automatic assumption that a participant is acting dishonestly.
