FraudSensor Overview

FraudSensor is HUMAN's post-bid solution for detecting advertising fraud. By analyzing each impression as it occurs, FraudSensor assembles detailed information about the quality of your advertising traffic and identifies different forms of invalid traffic (also known as IVT), including sophisticated IVT that closely mimics real human behavior.


If you're a MediaGuard user, FraudSensor's analysis can validate the pre-bid predictions you receive from MediaGuard. To learn more about using MediaGuard and FraudSensor together, see Closing the Loop.

How FraudSensor works

FraudSensor uses detection tags to collect a variety of signals about the users driving your ad impressions, including device characteristics, network information, and behavioral patterns. These signals provide us with enough information to determine whether each impression was valid or invalid. Any invalid impressions are sorted into different IVT categories with information about the specific traits displayed by that user.

You can view your FraudSensor data in the HUMAN Dashboard or via our Reporting API. Since FraudSensor performs its analysis after an impression has already occurred, you can't automatically incorporate this post-bid data into real-time bidding workflows; however, you can still use FraudSensor's IVT analysis to assess the quality of your ad traffic, see which traffic sources are driving the highest levels of invalid impressions, and adjust your future bidding criteria accordingly.

Get started with FraudSensor

If you'd like to get started with FraudSensor, a HUMAN representative will help you build your own unique detection tag to serve alongside your ad impressions. These detection tags are tailored to the specific environment where they'll be deployed and can be customized to include a wide variety of tag parameters.

We also recommend setting up an Impression Sync integration to help identify any bad actors who attempt to evade FraudSensor's detection tag.
