How We Solve It
Diagnostic Insight
"SMS pumping is a billing attack, not a security breach, which is why it often goes unnoticed until finance flags the invoice. Rate limiting per IP and per number, not just per account, is what actually stops it."
WebWorldMaker editorial analysis
We apply rate limiting, geo-pattern controls, and CAPTCHA-style friction on OTP-triggering endpoints, and monitor for the traffic signatures typical of pumping fraud, cutting off abuse before it inflates your bill.
