How ACH RiskLens Works

Background

Risk-Based Transaction Scoring

Each ACH entry is evaluated using transaction context and up to 90 days of historical behavior, producing:

  • SVG_margin Unauthorized ACH activity
  • SVG_margin Social engineering & account compromise
  • SVG_margin Elder financial exploitation
  • SVG_margin First-time or newly changed originators, SEC codes, or counterparties
Background (1)

ACH-Specific Risk Logic

Risk scoring incorporates fraud scenarios such as:

  • SVG_margin Unauthorized ACH activity
  • SVG_margin Social engineering & account compromise
  • SVG_margin Elder financial exploitation
  • SVG_margin First-time or newly changed originators, SEC codes, or counterparties
Background (2)

Anomaly Detection

ACH RiskLens identifies out-of-pattern behavior including:

  • SVG_margin Unusual amounts relative to historical norms
  • SVG_margin Abnormal frequency, velocity, or burst activity
  • SVG_margin New or infrequent counterparties
  • SVG_margin Material behavioral shifts over time

Metadata-Aware Analysis

Standardized ACH descriptors (e.g., PAYROLL, PURCHASE) are incorporated into risk scoring, with reporting on metadata usage and compliance alignment.
