Overview

We create a positive customer experience through real time call verification technology.

Fraudsters cost businesses time and money, and make life more difficult on real customers - whether that’s outright stealing cash or slowing down the phone call authentication process. Next Caller helps businesses fight criminals, not customers, by safely passing through legitimate callers and identifying suspicious interactions. Using VeriCall™, businesses have the opportunity to stop phone fraud before it starts. With our real-time RESTful API, Next Caller verifies good callers and detects spoofed calls to make your business Spoof Proof™ - flagging high-risk calls within milliseconds of the first ring. Based on this threat-level analysis of every call, a business can decide how to handle the customer or criminal on the other end of the line.
