Privacy-preserving AI/ML platforms for bot and fraud detection
A privacy-first security AI suite used by websites and apps to block bots and abuse, positioned as an independent alternative to reCAPTCHA.
An active-learning platform with robust APIs that automates the full train, deploy and improve cycle for computer-vision models.
Scoped and blinded signals that enrich risk scoring while keeping ML models compliant with global privacy laws and free of PII.
Detection models for credential stuffing, account takeover, card testing, chargeback fraud, purchase fraud and SMS tolling fraud.

Prove every user is real — invisibly and continuously.
Proof of Human runs silently behind login and checkout flows, scoring behavior in under 200 milliseconds without CAPTCHAs or friction for real people.
Continuous behavioral models look for programmatic typing, teleporting mouse movement, jump scrolling, centered clicks and pasted text to catch bots and AI agents mid-session.
The service states it collects no PII and does no cross-site tracking, helping teams meet compliance and privacy requirements.
A single script tag with a site key and user ID is enough to begin verifying sessions, and results include an example session report with explainable signals.
