Trustmi Payment Security Platform

Payment fraud prevention monitoring email, ERP, and finance to block social engineering.

Trustmi Payment Security Platform Overview

What it does

Trustmi is a Business-to-Business (B2B) payment security platform that stops socially engineered payment fraud, including Business Email Compromise (BEC), vendor impersonation, executive impersonation, and account takeover, before funds leave the company. Behavioral AI builds fingerprints of how each vendor, employee, and payment normally behaves across email, Enterprise Resource Planning (ERP), procurement, and payment systems, then correlates those signals to flag banking changes, invoice modifications, and payment requests that break the pattern, returning a Safe or Unsafe verdict on every payment before it is released.

How it works

Trustmi connects through Application Programming Interface (API) integrations to Microsoft 365, Google Workspace, SAP, Oracle, Coupa, SAP Ariba, and Acumatica with no software to install; the vendor states most customers are running within 30 minutes. Each payment receives a risk score and a Safe or Unsafe verdict with its signal trail, low-risk payments clear automatically, and exceptions route to human review. Modules cover Email Security, Payment Security, Payment Flows (duplicate and erroneous payment detection), Vendor Onboarding and Management (bank account and sanctions validation), and ACH compliance for Nacha's 2026 rules, with AI agents handling payment run diligence and fraud investigations.

Credentials and traction

Trustmi publishes SOC 1 Type II and SOC 2 Type II audit reports through a public trust center and states GDPR and CCPA compliance alongside AWS Qualified Software status. Awards displayed on its site include Best in Show at RSAC 2025, two Cyber Defense Magazine awards in 2024, and a 2023 Cybersecurity Breakthrough Award. Named customers include Blue Shield of California, Armis, Mohawk Industries, Colgate-Palmolive, CNA, Deloitte, United Rentals, and Chipotle; the company reports $240 billion in payments protected yearly.

Key Capabilities

mapped to solution categories
Integrated Cloud Email Security (ICES)

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.

Connects to Microsoft 365 or Google Workspace via native APIs for visibility into internal and delivered mail, enabling post-delivery clawback without changing MX records.

Analyzes email body text semantically to detect social engineering, pretexting, and urgency manipulation in messages that contain no malicious attachments or URLs.

Assesses the email communication risk posture of external supplier domains, flagging suppliers with poor email authentication, recent domain registration, or anomalous communication patterns.

Payment Security Monitoring

Detects duplicate invoices, mismatched amounts, and currency errors across entities and multiple ERPs by fuzzy-matching against invoice and payment history.

Scores every payment in the run and returns a Safe/Unsafe decision with the supporting signal trail before funds are released, auto-clearing low-risk items.

Evaluates each vendor banking-detail change request against the vendor's communication and payment history and who requested it, going beyond confirming the account exists.

Validates vendor identity, documents, and bank accounts at onboarding through a configurable vendor portal, with continuous sanctions screening across the vendor lifecycle.

Logs every control, score, and decision applied to ACH payments to evidence Nacha false-pretenses fraud monitoring requirements.

AI agent ingests the payment batch, scores each payment, clears safe items, routes exceptions with context, and produces the run report on request.

Correlates signals across email, ERP, procurement, invoice, and payment systems so a request that looks legitimate in each silo is flagged when the combined path breaks pattern.
