Fast-paced and sophisticated, telecoms fraud enabled by roaming is on the rise and moving across networks at an unbelievable rate. The industry has long since adopted fraud management that’s driven by detection in response, but roaming by its very nature has proven this approach unfit for purpose. For operators still relying on NRTRDE, HUR & TAP files to detect outbound roaming fraud, it’s time to move on – a proactive approach is now available that will stop fraudsters in their tracks.
Fraud in international traffic
International fraud incidents take place using complex techniques within the home network or when roaming. If using traditional approaches driven by detection, this makes fraud events almost impossible to stop before revenue losses and reputational damage have already occurred. Inevitably, roaming introduces further delays in fraud detection, and it’s this that presents a big opportunity for fraudsters. For the home operator it is particularly difficult, especially for voice calls, as the majority are not home routed and are managed by a roaming partner and its carrier of choice.
In the best case, a wait of up to four hours is incurred before the fraud traffic is visible through a NRTRDE file. To stop the incident takes longer still. More hours will pass, with further latency a result of file transfers and processing in the fraud management system, before the generation of an alert once the threshold is breached. This is followed by further delays during alert selection, analysis, verification until, finally, action can be taken by a fraud analyst to stop the fraud.
There is also little incentive for roaming partners to stop fraud incidents on their own, as they are not liable if the NRTRDE files are shared with the home network within four hours. Even if the home network disputes this with a roaming partner, it is their responsibility to pay the international interconnect charges owed by the roaming partner to its carrier of choice.
The result is that roaming is now the industry’s biggest exploit, costing operators in excess of US$10.4 billion annually. A single fraudulent SIM has been shown to generate an average of 18 hours of traffic, causing an average retail loss of US$4,800, with some incidents even incurring losses of up to US$50,000 per hour. Clearly, something needs to change. And fast.
BICS Voice Roaming Firewall is a completely unique solution for operators to take back control of their outbound roamer voice traffic, bottom line and customer experience, and protect their users and networks from fraud.
Delivering 24×7 proactive protection against voice fraud in roaming, the Voice Roaming Firewall will:
- Eliminate delays associated with NRTRDE file transfer followed by FMS based detection
- Access real-time coverage at the roaming signalling level
- Block traffic to more than 55 million known fraudulent numbers
- Benefit from crowdsourced fraud intelligence from more than 2000 partners worldwide
Capitalising on BICS’ position as the world’s largest roaming and signalling provider, BICS Voice Roaming Firewall is a completely managed service, saving operators time, resources and money compared with on-premise systems, including traditional fraud management systems, while the BICS global fraud view ensures that protection goes from strength to strength.
Powered by BICS’ unique global view of traffic patterns at the international level, its crowdsourcing platform collects new fraud intelligence on an ongoing basis from traffic exchanged with 2000 partners worldwide, including, but not limited to, international voice, signalling, SMS, roaming and cloud communications. As a result, BICS’ Fraud Intelligence Repository proactively detects and blocks calls to more than 55 million known fraudulent numbers, serving to eliminate the majority of fraudulent traffic, even before it connects to the destination. This is supplemented by real-time, pattern-based tracking, and automatic blocking of new fraud incidents at the signalling level associated with outbound roaming voice traffic.
One European operator blocked approximately a quarter of a million fraudulent calls and saved more than US$830,000 in just six months with the Voice Roaming Firewall service.
As telecoms fraud continues to rise, the Voice Roaming Firewall is cost effective, fully managed and fast to onboard. For operators taking the fight to fraudsters who are roaming as their preferred enabler, it’s also proven as a seriously effective last line of defence.
