Financial Impact Mitigation

By combating telecom bypass fraud, Bypass Shield significantly reduces financial losses. The CFCA estimated global industry experienced a notable increase in fraud-related financial losses. Compared to 2021, there was a 12% rise in fraud loss, amounting to an estimated $38.95 billion USD, underlining the financial impact that this solution can mitigate.

Turn-Key Solution and Speed

As a turn-key solution, Bypass Shield offers quick deployment and fast detection speeds, allowing telecom operators to rapidly respond to and mitigate fraud. This agility is crucial in the fast-paced telecom industry, where delays can lead to substantial revenue losses.

Common ways how telecom bypass fraud typically works

Call Rerouting

Fraudsters use various methods to reroute international or long-distance calls in a way that circumvents the standard international call routing paths. Instead of following established agreements and routes, they divert the calls to alternative, often unauthorized, routes.

Fraudulent Termination

Diverted calls are terminated on local networks or by using unauthorized routes, making them appear as if they are local or domestic calls. This allows fraudsters to avoid paying the higher fees associated with international call termination.

Revenue Loss

By terminating international calls as local ones, the fraudsters benefit from lower termination rates, which results in reduced revenue for the legitimate telecommunications providers that should have received payment for handling these calls.

Manipulation Techniques

Fraudsters may use a variety of techniques to carry out telecom bypass fraud, including SIM boxes (as mentioned in the previous response), voice over Internet Protocol (VoIP) gateways, or the manipulation of signaling and routing information.
