Tool Information
What is Castle.io?
Castle.io is a fraud prevention platform with SDKs and APIs that monitors users, detects bots, and blocks account abuse and in-app fraud. It provides a dual-layer system of edge and in-app defenses using SDKs, APIs, behavioral signals, and rules to stop bots, fake accounts, account takeovers, and other fraud and abuse in real time.
Core Features
Dual-layer fraud defense
