AI in SMS Firewall, working on its own.
AI that takes the action, not just the note. Running inside the network, on your brand.
Content classification
AI reads every message body and classifies it as transactional, promotional, conversational or fraudulent before delivery.
Sender ID scoring
Each alphanumeric and numeric originator is scored against known behaviour, and spoofed IDs are blocked automatically.
Auto policy action
The firewall acts on each verdict itself, allowing, blocking or flagging messages without waiting for an engineer.
