Messaging protection

Stop fraud at the message layer

SMS Firewall

Carrier-grade filtering of all inbound SMS: block grey routes, spam, spoofing and AIT while monetising legitimate A2P termination.

SMS Fraud Detection

Real-time identification of smishing, sender-ID spoofing and artificially inflated traffic before subscribers are hit.

Flash Calls Prevention

Detect and block flash-call verification bypass that silently erodes A2P SMS revenue, with policy controls on your terms.

Voice Fraud Shield

Protection against IRSF, wangiri, CLI spoofing and interconnect fraud, powered by live route intelligence.

OTT Bypass Control

Identify and prevent termination through OTT apps that bypasses your interconnect and drains legitimate revenue.

RCS Messaging Control

Visibility and policy management for RCS traffic as brands migrate from SMS — the next channel under control from day one.

Network security

Know your weaknesses before attackers do

SS7 Vulnerabilities Check

Assessment against SS7 attack vectors: location tracking, call and SMS interception, subscriber DoS and fraud entry points.

Network Protection Audit

End-to-end assessment of signalling, interconnects and firewall policies with a prioritised, actionable remediation plan.

SMS Routes Tests

Continuous testing of routing integrity: detect SIM-farm delivery, sender-ID tampering, content modification and fake DLRs.

Intelligence & operations

Number intelligence and managed operations

HLR Lookup

Real-time verification of mobile number status and network attachment — clean databases, cut waste and improve routing.

MNP Lookup

Accurate Mobile Number Portability resolution so every call and message reaches the subscriber’s actual operator.
