By default, the Analyst Station dashboard lists transactions that Account Protection has assigned the status of Review or Challenge. However, you can filter the display settings so that transactions with the status Block or Allow are also displayed. For instructions on how to filter the display settings, see Filtering the Transactions List.

Understanding the Recommendations that Account Protection Assigns to Transactions

All transactions that are displayed in the Analyst Station dashboard have a recommendation that has been assigned by Account Protection. These recommendations are extremely useful for the user to determine which transactions should be blocked, which transactions require further investigation to determine if they are malicious, and which transactions are safe and require no intervention. These recommendations cannot be changed by the user.

Account Protection assigns one of the following four recommendations to a transaction:

  1. Allow: This transaction shows normal behavior and requires no further follow-up.
  2. Block: Account Protection has identified this transaction as fraudulent with high confidence and recommends that you block it.
  3. Review: Account Protection has identified this transaction as suspicious and recommends that it be reviewed by your fraud team.
  4. Challenge: Account Protection has identified this transaction as needing further validation by some type of means such as CAPTCHA or multi-factor authentication.

System Overview

Find Transactions by Searching

Analyst Station’s search feature can be used to find transactions by means of the Transaction ID, Account ID, Device ID, or IP Address. An exact ID or IP Address must be entered in the search box to obtain results.

This feature can be very useful for finding a group of transactions that share the same Account ID, Device ID, or IP Address.
