Fraud Protection
Checking suspicious calls by rule and handling them deliberately
With CreaLog Fraud Protection, network operators can assess incoming and outgoing voice connections against configurable rules. Numbers, prefixes, number formats, relevant SIP information and connected data sources can all be taken into account.
The Fraud Protection Service detects anomalies in call behaviour in real time, evaluates signalling, identity, destination, timing and traffic patterns collectively, and blocks or flags suspicious calls before they result in significant costs.
The risk score combines deterministic rules, individual behaviour patterns and correlation analyses with AI and machine learning to accurately detect suspicious calls in real time, reduce false alarms and prevent financial losses at an early stage.
The validation and decision logic is based on the CreaLog SIP Application Server and can be adapted and extended within the Service Creation Environment.
Number and plausibility checks
Numbers can be checked by format, length, origin and defined numbering plans.
Allow and deny lists
Individual numbers or prefixes can be allowed, flagged or blocked.
Spoofing and Wangiri scenarios
Suspicious numbers and call patterns can be assessed against configurable criteria.
Graduated responses
Depending on the result, a call is forwarded, anonymised, logged, blocked or routed to a warning announcement.
