Trustmi Payment Security Platform

Trustmi is a Business-to-Business (B2B) payment security platform that protects payment processes from social engineering fraud including Business Email Compromise (BEC), vendor impersonation, executive fraud, and deepfake attacks by monitoring behavioral patterns across email platforms (Microsoft 365, Google Workspace), Enterprise Resource Planning (ERP) systems (SAP, Oracle, NetSuite), and financial software (QuickBooks, Xero, Workday). The platform analyzes hundreds of data points across the payment lifecycle from vendor onboarding through payment execution, creating behavioral fingerprints for vendors and employees to detect anomalies such as unauthorized banking changes, suspicious invoice modifications, or impersonation attempts, then automatically blocks fraudulent transactions before funds are transferred.

Trustmi correlates data across siloed systems to produce real-time risk scores and detect multi-vector attacks that manipulate multiple systems simultaneously, which individual security tools cannot identify, while the Trust Network leverages crowd-sourced intelligence from thousands of vendors to uncover suspicious signals. Fortune 500 customers including CNA Insurance and Colgate-Palmolive report operational improvements such as reducing payment report preparation from half a day to 30 minutes while improving security, with the platform offering modular deployment options including Email Security, Payment Security, Payment Flows management, Vendor Onboarding, and Claims Fraud modules.

Founded in 2021 by Shai Gabay (Chief Executive Officer (CEO), former Chief Information Security Officer (CISO) of Israel Discount Bank) and Eli Ben Nun (Chief Technology Officer (CTO), former Cynet Security), Trustmi has raised $21 million led by Zeev Ventures and Cyberstarts with participation from Tipalti CEO and Wiz CEO, growing to 48 employees. The platform received the 2024 Cybersecurity Excellence Award for Payment Security, 2025 RSA Conference Best in Show award, and 2025 Cyber Defense Magazine "Trailblazing" awards, while supporting Sarbanes-Oxley (SOX) compliance through automated reporting and control enforcement.
