User activity in Castle is enriched with IP address, UA, email, phone, and device fingerprint. In addition, risk score and risk signals are also included.
See an activity stream for a single user, including when they sign up, login, and execute transactions. All activity is enriched by Castle, helping you identify when fraud occurs.
See every customer interaction enriched with Castle's data, including IP, UA, email, risk score, risk signals and more. Spot potential fraud faster than ever.
Find situations where multiple users are using the same device. Flag a device as bad to stop further logins.
