Best Vendor Payment Fraud Prevention Software

Vendor payment fraud is payroll fraud's bigger sibling: same playbook (get a bank account changed, wait for the payment run), larger checks. The defenses stack in layers, verify the entity exists, verify the bank account belongs to it, watch the email channel where the change requests arrive, and audit what got paid. No single tool does all four, so this list is organized by layer.
