  1. Fast – On average, VisaNet fully processes transactions in approximately 1 second. Secure – VisaNet supports multiple defense layers to prevent network intrusions, protect against account fraud, and to make stolen card data unusable for criminalsincluding data encryption, sophisticated intrusion detection systems and neural network technology capable of analyzing each transaction in real-time. Over the last two years, Visa has spent more than $100 million on data security enhancements. Reliable – VisaNet runs multiple, parallel processing systems in highly redundant data centers. This ensures near 100 percent availability. In the past 15 years, VisaNet experienced less than two seconds average unavailability per year. State-of-the-art monitoring tools are in place to detect network availability and client-specific processing anomalies, such as high rates of decline.
