Vendor Information
Trustmi Payment Security Platform Overview
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.
Key Capabilities
Standardized capabilities mapped to this product's security niche
Builds per-user and per-vendor communication baselines from historical email patterns to detect anomalous content, timing, or sender behavior without relying on signatures or blocklists.
Detects compromised or spoofed third-party supplier accounts by analyzing communication pattern deviations, domain aging, and content signals, targeting invoice fraud and payment redirection attacks.
Detects signs of internal mailbox compromise (anomalous login geography, mail forwarding rule creation, unusual send volume), and can trigger automated session revocation.
Integrates via Microsoft 365 or Google Workspace APIs without requiring MX record changes, enabling parallel deployment alongside an existing SEG and post-delivery remediation.
Analyzes email body text semantically to detect social engineering, pretexting, and urgency manipulation in messages that contain no malicious attachments or URLs.
Discovers fake websites, social media profiles, and mobile applications impersonating the organization, using domain similarity, visual fingerprinting, and content analysis.
Monitors external sources for leaked personal data, credential exposure, targeted phishing infrastructure, and social media impersonation targeting named executives.
