Comparison
Castle vs Fingerprint
Who’s behind each, what their homepages track, what they cost and how often their policies changed, measured the same way for both. By what they offer, they’re very close.
Castle provides SDKs and APIs for detecting bots, account takeover, fake signups and in-app fraud using device fingerprinting, IP and email intelligence, behavioral analysis and a rules engine for real-time allow, challenge or deny decisions.
Fingerprint (formerly FingerprintJS) provides browser and device fingerprinting APIs and SDKs for web and mobile apps. They assign persistent visitor identifiers that support fraud prevention and bot detection.
