Carrier-Grade Messaging Firewall
Protect your messaging network against SMS pumping, grey routes, OTP fraud, and unwanted traffic — in real time. TeleSystems Firewall deploys intelligent, configurable rules that keep your routes clean and your reputation intact.
Every Layer of Defense, Unified
TeleSystems Firewall combines real-time rule enforcement with machine-learning threat intelligence to protect your messaging infrastructure from every angle.
SMS Pumping Prevention
Detect and block artificially inflated SMS traffic in real time. Our ML models identify abnormal send patterns and automatically throttle or block suspected pumping campaigns before they cost you.
Grey Route Blocking
Prevent revenue leakage caused by off-net grey routes. TeleSystems Firewall inspects every message for protocol anomalies, unauthorized sender IDs, and bypass routing techniques.
OTP & Fraud Traffic Detection
Identify and filter fraudulent OTP flows, flash-call abuse, and impersonation attempts. Keep your verification channels trusted and compliant with financial and identity regulations.
ML-Based Anomaly Detection
Continuously trained machine-learning models analyze traffic patterns across routes, senders, and destinations — flagging deviations before they escalate into incidents.
Granular Rule Configuration
Define and deploy custom firewall rules per MCC/MNC, sender, destination, content keyword, or traffic volume threshold. Full flexibility without sacrificing speed.
Real-Time Monitoring & Alerting
Live dashboards with per-route traffic visibility. Set custom alert thresholds and receive instant notifications when threats are detected or rules trigger.
Protection That Works Transparently
Our inline firewall architecture processes every message in real time with no impact on legitimate traffic throughput.
Traffic Ingestion
All inbound and outbound messaging traffic passes through the TeleSystems Firewall layer before reaching your core network or delivery routes. No changes to your existing architecture required.
Rule & Policy Evaluation
Each message is evaluated against your configured rule sets — checking sender IDs, destination ranges, content patterns, volume thresholds, and known fraud signatures in under 5 milliseconds.
ML Threat Scoring
Messages that pass static rules are then scored by our anomaly detection engine. Traffic deviating from established baselines is flagged for review or automatically blocked based on your policy.
Action & Reporting
Blocked or flagged messages trigger real-time alerts. Every firewall action is logged with full context — sender, destination, rule triggered, and timestamp — giving you a complete audit trail.
Built for Every Node in the Messaging Chain
Whether you operate a network, aggregate traffic, or build customer-facing applications, TeleSystems Firewall adapts to your architecture and threat model.
Mobile Network Operators
MNOs deploying TeleSystems Firewall gain full visibility into A2P and P2P traffic crossing their network. Identify grey routes, eliminate revenue leakage, and enforce GSMA-compliant filtering policies at scale.
CPaaS & Aggregators
Messaging aggregators use our firewall to ensure clean traffic passes downstream to their carrier partners. Protect your interconnect relationships and SLAs with proactive fraud filtering before messages leave your platform.
Financial Services
Banks and fintech platforms rely on TeleSystems Firewall to secure OTP delivery channels. Prevent SIM-swap attacks, SMS interception, and flash-call bypass that could compromise customer accounts.
Enterprise Security Teams
Large enterprises with high-volume messaging campaigns protect their sender reputation with our content filtering and anomaly detection. Ensure your brand is never weaponised by fraudulent traffic on shared routes.
