PaymentKnox for Accounts Payable is a payment security solution by NSKnox designed to protect organizations against fraud and errors in the accounts payable process. The product focuses on validating and verifying payment details — such as bank account information and beneficiary data — before payments are executed, reducing the risk of fraudulent or misdirected transactions. The solution addresses threats such as Business Email Compromise (BEC), vendor fraud, and payment redirection attacks, where attackers manipulate payment details to divert funds to unauthorized accounts. By validating payment data against authoritative sources, it aims to ensure that payments reach the intended and legitimate recipients. PaymentKnox for Accounts Payable is targeted at finance and security teams within enterprises that process large volumes of outgoing payments and need controls to detect and prevent fraudulent payment instructions before funds are transferred.
