Privacy-first bot detection and fraud prevention for the web
Multi-layered detection delivers risk scores and near-zero false positives, with passive and no-CAPTCHA modes.
Stop transaction fraud, account takeovers and multi-accounting with privacy-preserving signals and no PII.
A stronger, toll-free alternative to SMS MFA that reduces fraud while simplifying the user experience.
Build custom risk models with adaptive learning and enrich your own ML using blinded, compliant signals.

AI-assisted URL threat detection API for developers
Every scan returns a numeric score plus explanatory reasons, so you can act on a link with confidence rather than trusting an opaque verdict.
Short links and redirect chains are unwrapped and followed, revealing hidden final destinations before they reach your users.
Links are classified across phishing, malware, scam, adult, dating, gambling, crypto and spam, supporting nuanced content policies.
Send batches of URLs in a single request and receive per-link risk scores, which suits high-volume pipelines and link shorteners.
