What AB Handshake does
AB Handshake Corporation is a Miami-headquartered, privately held telecom anti-fraud technology company founded in 2020, operating across voice and SMS fraud prevention for mobile network operators, MVNOs, wholesale carriers, and IPX providers globally. The company's platform is anchored by a patented out-of-band call validation protocol that creates a virtual handshake between originating and terminating operators to validate call events (START, CONNECT, END) and A/B numbers independently of signaling channels, complemented by AI Shield, a machine learning engine analyzing 150-200+ parameters in real time. Supporting modules include AB SMS Security, Fraud Radar (community-shared fraud intelligence API), Flash Call Detector, Voice Traffic Checkup (offline CDR analysis), Test Call Generator, CLI Spoofing Prevention, AIT Prevention, and a National Anti-Fraud Platform for regulators. The platform processes 300M+ daily interactions across 160+ operators and is listed by CEPT as an effective CLI spoofing solution.
The company monetizes through a multi-stream model: subscription-based software licenses (monthly or annual), pay-as-you-go usage-based pricing tied to validated traffic, white-label/OEM licensing (notably through Vodafone Voice Protect and Cataleya's Orchid Link SBC), revenue-share arrangements with partners, and transaction-based monetization of detected flash calls. Distribution combines direct enterprise field sales with a three-tier partner program (technological, solution, and sales partners) and embedded OEM channels. Customer segments span MNOs/MVNOs (primary), wholesale carriers and IPX providers (primary), enterprises in banking/insurance/payments (primary), national regulators (secondary), and IPX/SS7-SIP gateway operators (secondary). Award validation includes Juniper Future Digital Awards 2026 Platinum, ROCCO Hackathon 2025, Global InfoSec Awards 2022, and multiple Stevie Awards.
