Monetization of A2P SMS traffic

Unscrupulous aggregators use various gray routes and SIM boxes to reduce the cost of delivering commercial SMS messages. Such actions can bring significant losses to mobile operators.

Identify gray routes

The platform allows the operator to determine in which cases the SMS aggregator tries to avoid paying for the termination of A2P messages and sends them along "gray" routes, for example:

In inter-operator messaging – through partner operators using P2P;

In international traffic which aggregators disguise as local traffic.

Find SIM boxes

Using SIM cards with cheap texting options, SMS aggregators can pass off A2P traffic as P2P traffic generated by ordinary subscribers. Our solution automatically blocks messages from SIM boxes and submits historical data to combat fraud.

Anti-fraud

SMS Homerouting Flooding MT Faking MO Spoofing

When making a broadcast, operators have to reveal subscriber ID and location. This is unsafe as it opens opportunities for SS7 attacks such as tracking subscriber locations, interception of SMS and voice calls.
SMS Home Routing allows operators to deliver messages from third party networks without disclosing the identifiers of their subscribers.
Flooding refers to large number of messages sent to a subscriber or another system, which leads to overload of signal links (SS7) and delayed delivery of other messages.
Our system blocks messages from certain subscribers, SMS centers or sender GT after a threshold of MO and MT messages is exceeded.
MT Faking occurs when a remote system uses the identifier of a real authorized SMS center, not allowing the home operator to receive payments for traffic termination.
Our system blocks messages in case of mismatches between the sender GT and the SMSC address.
MO Spoofing means illegal mailing through emulation of roaming subscriber, as a result of which subscribers are charged for messages they did not send.
Our system blocks messages sent from a subscriber if the MSC GT in the request is different from the MSC that actually serves the subscriber.

Anti-spam

Spam Campaign Analyzer

The module automatically recognizes spam thanks to dynamic learning on scanned messages.

Text analyzer

The system forms black and white lists of texts for message filtering. The system supports text analysis by key characters, words, phrases and patterns with regular expressions.
The system can process glued messages and supports for GSM Alphabet and UCS2 encodings.

Protection from smishing

Multi-level protection against extortion of the subscriber's confidential data via SMS. On the basic level, the system provides protection by identifying links that redirect the user to other sites. For additional verification of links found in messages, you can integrate the system with external phishing databases (OpenPhish , PhishTank or GoogleWebrisk).
