Anti-Fraud SMS · For Mobile Network Operators
Stop SMS fraud before it reaches the subscriber.
Smishing, sender-ID spoofing, premium-rate abuse, OTP interception — all in one layer.
BroadNet's anti-fraud SMS layer combines a deterministic rule engine (sender-ID, content, route) with behavioural ML (per-MSISDN baseline, anomaly detection) to identify and block fraudulent SMS — smishing, spoofing, premium-rate fraud, OTP-interception attempts. Deployed inline at the operator edge, decisions in under a millisecond.

Capabilities
Six fraud surfaces, one inline layer.
Rule engine and behavioural ML run side-by-side — the rule engine catches known fraud in microseconds; the ML catches the novel patterns the rules haven't seen yet.
Sender-ID spoofing
Cryptographic and registry-based validation of every alphanumeric sender. Catch bank, government, and mobile-operator impersonation before delivery.
Registry-backedBank-gradeReal-time
Behavioural anomalies
Per-subscriber baseline; alert on sudden inbound bursts (likely OTP-interception staging) and unusual sender-IP / route combinations.
Per-MSISDN baselineBurst detectRoute anomaly
Threat-intel feeds
Integrates with industry threat-intel platforms — IOC sharing across BroadNet-deployed networks for the same fraud campaign.

Premium-rate abuse
Detect SMS-billing fraud and unauthorised premium-rate originations. Quarantine, alert, or block per operator policy.
PRS detectAuto-quarantinePolicy-driven
Subscriber-safe audit
Every block decision logged with reason, score, rule version, and operator ID. Subscribers can be notified or shielded entirely.

Outcomes
Less fraud reaching subscribers. Higher delivery quality.
The anti-fraud layer stops smishing and spoofed senders inline, before they reach subscribers. Results depend on each network's traffic, so we do not publish a benchmark figure.
