NSKnox Dynamic Positive Pay for Electronic Payments is a payment security solution designed to protect organizations against fraudulent or erroneous electronic payment transactions. The product applies the traditional "Positive Pay" concept — originally used for check fraud prevention — to electronic payment methods such as ACH, wire transfers, and other digital payment types. It works by validating payment instructions against pre-authorized payment data to detect discrepancies that may indicate fraud, manipulation, or error before funds are disbursed. The "Dynamic" aspect refers to the solution's ability to perform real-time or near-real-time verification of payment details, enabling organizations to catch unauthorized or altered payment instructions at the point of execution rather than after the fact. The solution is aimed at corporate treasury, finance, and accounts payable teams seeking to reduce exposure to Business Email Compromise (BEC), vendor fraud, account takeover, and payment redirection schemes that target electronic payment workflows.
