Stop OTP Spamming Without Slowing Down Real Users

A multilayered security system that stops abusive OTP requests at the device level, protecting your OTP budget and your users without adding friction to genuine logins.

OTP Spamming: Draining Budgets, One Request at a Time

Bots and fraudsters hammer your OTP endpoints to rack up delivery costs, harass users, or brute-force verification codes.

Skyrocketing Delivery Costs

Every fraudulent OTP request is a message you pay for, over SMS, WhatsApp or email, so automated spam turns your verification flow into a running bill.

SMS Pumping and Toll Fraud

If you deliver codes over SMS, fraudsters trigger OTPs to numbers they control and profit from the termination fees your business pays.

Harassed Users

Victims get flooded with unsolicited verification codes, eroding trust in your brand and generating support tickets.

Brute-Force Attempts

Repeated OTP requests give attackers more chances to guess or intercept codes and take over accounts.

Degraded Service

Spam traffic overloads your authentication flow and whichever gateway delivers your codes, slowing down OTP delivery for genuine users.

Hidden in Normal Traffic

Rotating IPs, emulators, and scripts make spam requests look legitimate to simple per-number rate limits.
