Releases

Release 3.1 (June 2025)

• Trusted Numbers. Prevent your trusted customers' SMS traffic from being blocked by Fraud Defender protections. You can bypass your own configured protections (traffic rules, AIT Protection, SMS Burst Protection). Check our developer guide to learn more.
• New AIT Protection Algorithm. The AIT Protection algorithm is now enhanced; the goal is to increase quality by reducing false positives while still effectively blocking fraudulent activity.
• Multiple Alert Actions per country basis. It is now possible to create multiple alert actions for the same fraud alert by defining different alert thresholds and actions. You can also apply the alert action to trigger only for certain country prefixes. Check our developer guide to learn more.
• New Fraud Alerts Search. Fraud alerts filtering capabilities have been enhanced to allow you: filter by date, alert type, and product.

Release 3.0 (May 2025)

• Fraud Defender Premium. The Fraud Defender Premium package is now available, which includes Custom Fraud Alerts, you can check package pricing and request and upgrade here. Custom Fraud Alerts allow setting per product (Voice and SMS) and country traffic limits, once the limit is reached a Fraud Alert will be raised for you to review, to know more about Custom Fraud Alerts check our developer guide.

Release 2.2 (May 2025)

• AIT Protection new algorithm. The AIT protection algorithm has been updated and enriched with a new data source to significantly reduce the amount of false positives while still blocking fraud effectively.

Release 2.1 (April 2025)

• Fraud Defender Advanced SMS Burst Protection. Fraud Defender Advanced now includes SMS Burst Protection at no additional cost. SMS Burst Protection allows you to define a per country maximum traffic limit; once reached, all traffic above the threshold will be rejected with error code 22. Visit the developer documentation to see the SMS Burst Protection supported countries list and additional feature details.

Release 2.0 (January 2025)

• Fraud Defender Advanced Release. The Fraud Defender Advanced version is now available! You can explore it in the Fraud Defender Dashboard by navigating to the Protections section. In addition to the existing Fraud Defender Standard protections (Traffic Rules & Volumetric Changes), the Advanced version includes access to Artificially Inflated (AIT) Protection. AIT Protection automatically detects fraudulent traffic and either blocks it or, if preferred, triggers an alert when fraudulent activity is detected. To learn more about the AIT Protection feature, refer to the Fraud Prevention API and Developer Documentation.

Release 1.2 (August 2024)

• New Dashboard: The new Fraud Defender Dashboard replaces the lateral navigation menu. When you click on the Fraud Defender section you will be directed to the new dashboard, from there you will be able to navigate to the rest of the Fraud Defender site sections.
• Alert Rules have been renamed to Alert Actions. Your Fraud Alerts are automatically raised. Through Alert Actions, you can define actions and email notifications to trigger once the Fraud Alert reaches your defined threshold. In any case, an Alert Action influences when a Fraud Alert is raised.
• Alert Actions Modal Improvements. Now you can easily trigger your action for every Fraud Alert by selecting option “Trigger action for every Fraud Alert”, or, if you prefer, set a threshold value for the action to trigger.
• Minimum threshold validation. Volumetric Fraud Alerts require a minimum of 1,000 SMS/calls in the last 12 hours to be raised, and we have added validation for the Alert Actions threshold, preventing values below 1,000.
• Volumetric Alerts Email Notifications. We have enhanced the email notifications providing additional details about the alert volume and the applied automated actions.

Release 1.1 (June 2024)

This release includes:

• AIT protection (both configuration and alerts)
• Fraud Defender dashboard
• Endpoints for traffic rules and AIT protection configuration exposed
• Traffic rules redesign

Release 1.0 (July 2023)

• When are Fraud Alerts generated? This release implements Volumetric fraud alerts. A volumetric fraud alert is generated when an abnormal traffic volume spike is detected based on the following criteria:

  • Absolute traffic volume observed on the API key in the past 12 hours is greater than 1,000 voice calls or 1,000 SMS messages.
  • In addition, the observed traffic volume in the past 12 hours is more than 6 standard deviations from the historical traffic mean over the past 90 days for the API key

  The above criteria are applied on a per-country basis. As a result, the volumetric fraud alert should only fire during a significant traffic spike that deviates significantly from normal traffic toward a destination.

• How do I set my email address to receive fraud alert notifications? Your Fraud Notification email address is set in the API Settings menu under the Notifications tab. You can add multiple email addresses to the fraud alert subscription.

• Can I receive other types of Fraud Alerts or set my own Fraud Alert thresholds? Further alert types and improved alert resolution will be added incrementally once they become available.

• Can I create multiple Alert Actions to notify at one threshold but block at a higher threshold? In this release a single Alert Action per traffic type (voice/sms) is supported. The ability to set multiple alerts will be added in a future release.

• How do alert thresholds work? The alert action threshold enables you to control how Fraud Defender responds to an incoming Fraud Alert by specifying what action to take based on the Action Threshold and Time Interval

  • Action Threshold is the minimum threshold at which the alert action will be triggered. For example, increasing the action threshold from the default of 1,000 to 5,000 would result in Fraud Defender ignoring smaller fraud alerts. This may be useful if Fraud Defender is generating too many email alerts based on normal ‘high burst’ usage patterns. Raising the limit to a more appropriate level would ignore expected spikes in your traffic, and only alert on a larger attack. Alternatively if choosing to auto-block traffic, you may choose a much higher threshold to avoid accidental blocking under normal usage conditions. Note: setting higher limits increases your risk exposure to fraud.
  • The Time Interval controls the grouping of incoming alerts to avoid sending too many notification emails when multiple alerts are raised. New fraud alerts received during the specified interval for the same product & country/prefix will be grouped together and will not result in a further email until the time interval expires. At that point a new alert group is created and another notification may be sent based on your Alert Action preferences.

• I only need to send traffic to a limited number of countries. How do I block traffic to all countries except these without creating hundreds of rules? A "block all" rule is not supported in this release, but there is a simple workaround.

  • Firstly, create ALLOW rules for the countries you wish to send traffic to. Please ensure these are in place before proceeding to create block rules, else traffic will be dropped as soon as the subsequent BLOCK rules are created.
  • Secondly, creating 9 BLOCK rules will achieve a global "block all" (BLOCK 1, BLOCK 2, …., BLOCK 9).
