NSKnox Bank Account Certificates is a payment security product designed to verify and validate the authenticity of bank account details used in business transactions. The product issues digital certificates that attest to the legitimacy of bank account information, helping organizations prevent fraudulent payment redirections and business email compromise (BEC) attacks that target financial transactions. The core mechanism involves certifying bank account credentials so that payers can confirm they are sending funds to the correct, verified recipient account. This addresses a common attack vector where fraudsters intercept or manipulate payment instructions to redirect funds to accounts they control. The product is aimed at corporate finance and treasury teams seeking to reduce payment fraud risk without requiring changes to existing banking relationships or payment infrastructure.
