Data Points

Multiple checks. One clean signup.

Our uniquely crafted algorithm analyzes multiple signals together to deliver one clear, instant decision.

Device fingerprinting

Build a persistent device signature from hardware, software and behavioral signals to detect device reuse, emulators, headless browsers and cross-account abuse — even in private or incognito sessions.

Instant risk decisions

Our engine fuses signals from multiple layers and returns allow / flag / block recommendations in ~200ms. Configure thresholds to automatically block high-risk signups, challenge medium risk, or let low risk pass.

Allow — Low risk

Challenge — Medium risk

Block — High risk

Email intelligence

Large, continuously-updated disposable domain database, MX validation with caching & timeouts, alias detection and role-email rules to catch throwaway and invalid addresses.

Malicious IP & threat feeds

Realtime IP reputation checks and curated threat lists plus global threat signals to identify known bad actors and bot networks.
