Intelligence - Get started



To add this product to your account, contact a Telesign expert. This product is available for full-service accounts only.

Use Telesign Intelligence to get a risk score and related insights. You can either feed this data into your risk model or decide whether to proceed based on a risk score threshold.

Basic usage

  1. A user inputs contact data and initiates an action on your site.
  2. Your application takes their contact data and any other identity data you have for them (such as IP address) and includes it in a POST /intelligence request.
  3. The service responds with a risk score and reason codes. These can be used to power your verification risk model or you can make a decision based directly on the score. See Decision matrix below.
  4. If you are satisfied with the evaluation of the user, you can allow the action to proceed on your site.

Decision matrix

Although this service returns Telesign's overall assessment of the risk of a user, you make the final decision about whether to proceed. We recommend creating a decision matrix like the one below, to determine how your integration will process user attempts.
