Fraud Solution Profile

Smartnumbers Protect

Prevent contact centre fraud and authenticate legitimate customers before you answer. 

Smartnumbers patented Call DNA™ technology assigns a risk score to calls by examining more than 200 features derived from carrier-level call signalling data. Each incoming call is tagged in real-time with the level of risk the call represents, such as:

  • Spoofed numbers
  • Withheld calls
  • Call type, such as VoIP
  • Calls from bad actors, including calls where the presentation ID is withheld
  • Calls from international locations
  • Suspicious behaviour such as repeat calls, especially from withheld numbers

Real-time reporting & visual insights

Smartnumbers provides you with real-time reports to show details about suspicious characteristics to enable you to identify trends and changes in fraudulent behaviour, for example: 

  • The number of calls received and the number of high-risk calls. 
  • Visual representations of the volume, type and the country of origin of suspicious calls. 
  • Carrier level call meta-data and risk indicators for every call. 

Fraud consortium

We provide you with proactive, real-time protection from confirmed fraudsters who have attacked other Smartnumbers users.

As a Smartnumbers customer, you receive instant access to the fraud consortium, a dedicated telephone fraud network, focused on sharing fraud intelligence to spot emerging contact centre fraud threats. 

The fraud consortium allows you to share and receive details about validated fraudsters in real-time, enabling you to keep track of changing malicious behaviour within your industry and cross-sector.

Fraud investigate

Our fraud investigation capability provides insight into the scale and behaviour of individual fraudsters. 

Smartnumbers Call DNA™ technology creates a unique profile of each caller. This can be used to discover related calls from the same fraudster even when they have withheld their phone number. It also enables you to identify other accounts they have targeted.
