WorkPro's automated reference checking solution includes both browser and device IP fraud detection.
Additionally, if IP fraud is detected, you will receive an email alerting you (see sample below), and a warning will be shown on the user interface with the finalised reference check, so you can make your own enquiries and determine how best to move forward with the candidate.
Note that once the reference check is finalised, if fraud is detected, you will need to send a new reference check request if you are not comfortable with the detected fraud, you cannot send a new reference as part of that reference check.
