About
Castle is a fraud prevention platform offering a dual-layer defense that operates at both the network edge and inside applications. It provides SDKs and APIs for bot detection, device fingerprinting, behavioral analysis, and AI-based risk scoring to stop account takeovers, fake signups, and multi-accounting. Teams can deploy in monitoring mode and switch to active blocking without DNS changes or long-term contracts.
Problem
Online platforms suffer from bots, fake accounts, account takeovers, and in-app fraud that traditional security tools handle poorly or in a disconnected way.
For
developers and security teams building web or mobile applications
How it works
Castle integrates via SDKs and APIs to monitor every request at the edge and in-app, applying device fingerprinting, behavioral signals, and AI scoring to enforce real-time allow, challenge, or deny rules.
