Kaidn is fraud detection software that scores signups, logins, checkouts, and withdrawals via a single API call to prevent fraudulent transactions. It analyzes connection handshakes before pages load, focusing on the protocol layer that fraudsters cannot easily manipulate, unlike browser or IP claims. This approach detects fake browsers and spoofed devices missed by traditional systems. Kaidn offers transparent allow, review, or block decisions with human-readable explanations for support teams to share with customers. It integrates shared intelligence across its network, flagging fraudsters caught by one operator for others while protecting privacy. The platform identifies VPNs, proxies, returning devices, velocity anomalies, and email patterns. Integration is simple via REST calls or Node.js SDK, with no mandatory onboarding. A dashboard displays decision signals and weightings. Free tools and a free tier enable evaluation on real traffic.
