Part of Visa's multi-layered approach to security, available through most issuers*, is the Visa Advanced Authorization (VAA) tool.
VAA is a comprehensive risk management tool that monitors and evaluates VisaNet® authorizations in real time, helping you immediately identify and respond to emerging fraud patterns and trends. As transactions are processed through the VisaNet system, VAA evaluates the authorization request data and assesses and assigns risk, allowing you to evaluate and make more informed decisions.
VAA assesses transaction data on an account level and from an event-level perspective, then delivers dynamic multi-dimensional risk information with every authorization message.
Using Visa's powerful analytical processing technologies and global monitoring of high-risk activities, VAA provides immediate alerts to fraud schemes.
With VAA, each VisaNet authorization message is populated with two types of risk information:
The Risk Score indicates the probability of fraud risk associated with a given transaction.
The Compound Account Risk Condition Code groups together unusual populations, events and/or spending behaviours, and assigns a risk evaluator.
VAA information helps you to identify various types of fraud schemes and patterns, so you can stop potential fraud losses before the transactions are complete.
