In response to the prevalence of online fraud, many fraud detection and prevention software service companies have entered the field, employing a variety of techniques, including machine-learning-based behavior analytics and anomaly detection; the use of a "fraud hub" that enables third-party data sources to feed in purchaser information that is used in predictive statistical modeling; and automated remote malware detection. The largest players in this area are Cybersource (owned by VISA), Brighterion (Mastercard), and SAS Institute. Some of the newcomers in the field include Signifyd, Kount, Riskified, Sift Science, Forter and Feedzai.[1]
