We help security, fraud, and customer teams quickly discover and stop suspicious activity, terms of service violations, and outright fraud.
Look at high level trends and spot patterns of abuse.
Browse high-level activity metrics to keep an eye on attacks in progress or look for malicious activity.
Drill into malicious activity. Uncover new attacks and create a plan for how to mitigate.
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.
Adjust policies in real-time to change what user actions to allow, challenge or deny. No need to wait for the development team to push code updates.
Take advantage of Castle's machine learning trained risk models to automatically stop malicious bots and humans.
Stop more types of malicious activity by using Castle at the edge and at the server. Castle's SDKs support most common client and server side programming environments.
Decide what's important based on your specific needs. Our APIs are flexible, and easy to adopt.
