Cross-border Payment Gateway Security Verification: IP Whitelist Configuration Steps

Why do cross-border payments need proxy IPs for whitelist verification?

Cross-border payment system has to deal with transaction requests from all over the world every day, and payment gateways usually require partners to bind fixed IP addresses in order to prevent malicious attacks. However, many enterprises encounter two problems in their actual business:

1. Self-built server IP is easy to be blocked by blacklists
2. Multinational branch offices require IP access in different regions

At this point in time, it's a good idea to go through theipipgo proxy ip serviceEstablishing a whitelist pool not only meets the security requirements of the payment platform, but also flexibly adapts to the needs of multi-region business. For example, the acquiring business in the Philippines uses local residential IPs, and the settlement system in Europe uses German static IPs, so that different business lines do not affect each other.

Three Steps to Complete Payment Gateway Whitelist Configuration

Key problem solutions

Issue 1: Payment platforms limit the frequency of IP changes
Using ipipgo'sLong-term Fixed IP PackageA single IP can remain unchanged for a maximum of 12 months, which meets the certification requirements of card organizations such as VISA. When changes are indeed required, the change plan is reported to the payment platform 72 hours in advance.

Issue 2: Multi-region IP unified management
Creating "Payment Dedicated IP Pool", centralize the management of IPs from business regions such as the United States, Singapore, and the United Kingdom. Ensure that the financial system can only call designated country IPs by setting access rights.

A: Check for three common causes:
