Alert Scores

1920

Alert Scores determine the importance of a newly generated alert.

Scores are build on a machine learning model that learns from your previous alerts to determine how important your new alerts are.

Alert Scores work on a scale of 0-100 to provide a numerical value that fraud agents can easily interpret. This value can also be used to triage alerts into alert queues.

Alert Queues can be easily sorted by alert scores, so only the highest priority alerts get the attention they deserve. This makes the process of working through alerts easier and reduces false-positive rates to free up your team’s valuable time.

If you are interested in turning on Alert Scores for your organization, please contact your Unit21 rep. Our expert ML team will create a custom model for you.

Once your model is live, you can find alert scores in the Alerts page. Make sure that the column for Alert Scores is visible by customizing your view:

Alert Scores are based on a vetted machine learning model that is trained on your prior alert dispositions and behaviors.

The Alert score appears in the Summary section of the Alert detail page:

1541

If you want to know how the score is computed, you can click on the Alert score tab:

1541

The tab will show which information from the alert (such as instrument name, age of entity...) we used to compute the alert score:

1530

In this example, the last receiver instrument holds the greatest negative weight in the score computation. Whereas max alert hit transaction holds the greatest positive weight in the alert score:

  • Red features contribute to increase Alert Score
  • Blue features contribute to decrease Alert Score

Every time you press the Show More button, you will see additional items used in the computation:
