As a leading provider of cross-border payment and acquiring infrastructure, YouDuPay treats data security, payment compliance and settlement safety as its core lifeline. We have built a technical defense and risk-control matrix that meets the highest international standards, delivering rock-solid protection for merchants and global buyers alike.
YouDuPay strictly adheres to the Payment Card Industry Data Security Standard (PCI-DSS Level 1), ensuring that all sensitive cardholder data (CHD) is protected with bank-grade encryption throughout its entire lifecycle — collection, transmission and storage.
All API endpoints, merchant dashboards and checkout pages enforce the latest TLS 1.3 cryptographic protocol, eliminating man-in-the-middle (MitM) attacks and eavesdropping risks.
Our multi-dimensional behavioral risk-control matrix, combined with EMVCo 3DS 2.0+ strong customer authentication, blocks stolen cards, credential stuffing and malicious fraud in real time — effectively shielding merchants from chargebacks.
We strictly enforce international AML (Anti-Money Laundering) and KYC (Know Your Customer) compliance reviews. Merchant funds are strictly segregated from platform operating funds and cleared in compliance, keeping the money flow transparent, lawful and efficient.
If you are a security researcher or have discovered a potential vulnerability, we encourage you to report it through responsible channels. Please contact our security incident response team (PSIRT) directly:
