Introduction to Castle

Castle is a fraud prevention platform that offers you a holistic view of risky customers across web and mobile, and lets you implement mitigation workflows faster than any ever before.

With Castle, you can:

• Perform Device Fingerprinting to uniquely identify devices that survive resets
• Use Risk Scoring to detect bots, account takeovers, and general account abuse
• Use Lists to block or trust any entity, including devices, IPs, and users
• Use Policies to implement no-code rules
• Use Custom Signals to implement real-time velocity queries that'll tag risky events

Now, let's get started with the implementation by reading the Integration guide.
