Comparison
Auth0 vs Castle
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.
Auth0, owned by Okta, is a hosted authentication and authorization service that developers use to add login, sign-up, single sign-on, multi-factor authentication and access control to their applications and APIs.
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.
