The problem with autonomous blocking
SMS traffic mixes OTPs, banking alerts, government notices and personal messages. A classifier that blocks on its own can stop legitimate traffic at the worst possible moment, and operators carry the regulatory and commercial consequences. AI in a firewall should make analysts faster, not replace their authority.
How Guardivia sequences it
The Guardivia SMS Signaling and ESME Gateway Firewall follows a fixed governance sequence:
- Monitoring and learning mode first, with no enforcement
- Traffic baselines per route, sender, account and time of day
- Analysis of content, sender behaviour, route behaviour and emerging patterns
- Proposed classifications, rules and thresholds with supporting evidence
- An AI operational coworker issuing daily recommendations early in operation, typically weekly once traffic stabilises
- Review and confirmation by an authorised engineer before any enforcement change
What this means for operators
Every block has a reason code, a rule or profile match and an audit trail that names the engineer who confirmed it. Because the classifiers and rule engine are developed in house, the QoS Engineering Team can adjust models to a specific market's language, sender ecosystem and regulatory expectations without waiting for an external vendor.
