WEpayments employs a comprehensive monitoring and risk management framework to ensure transaction security, regulatory compliance, and fraud prevention. This guide explains transactional monitoring, restrictive lists, anti-fraud procedures, and MED fraud notifications.

Transactional Monitoring

Transactional monitoring is the continuous real-time analysis of all payments processed through the WEpayments platform. Its purpose is to identify suspicious patterns, prevent fraud, and ensure compliance with regulatory requirements (including Central Bank of Brazil and anti-money laundering regulations).

What is monitored?

💡 Monitoring applies to both Payin (incoming) and Payout (outgoing) transactions.

Restrictive Lists

WEpayments maintains and cross-references multiple restrictive lists as part of our compliance framework.

Types of restrictive lists

How restrictive lists impact your transactions
