Transaction Risk Consulting

Transaction Risk Assessment

Auditing transactional processing pathways to isolate friction points, authorization leakage, and processing anomalies.

Assessment Inclusions

  • Deep-dive auditing of transaction authorization, routing pathways, and capture protocols.
  • Inspection of gateway velocity checks, card validation controls, and decline handling.
  • Review of cross-border currency conversion exposures and multi-currency processing risks.

Problems It Addresses

  • Elevated transaction decline rates impairing legitimate cardholder conversions.
  • Unchecked transaction velocities indicating automated card-testing operations.
  • Opaque merchant fee deductions stemming from misconfigured processing interchange categories.

Written Deliverables

  • Transaction Pathway Audit & Vulnerability Assessment Report.
  • Authorization Rate Optimization & Gateway Parameter Checklist.
  • Velocity Rule Tuning Blueprint for payment engineering teams.
