Account protection — not just a device ID

Fingerprint tools excel at remembering a browser. AbuseGraph is built for signup and login decisions you can act on and defend.

Where we win

Transparent decisions
Score, verdict, and plain-language reasons — not a mystery visitor ID.
Free forever + free test keys
1,000 live checks / month on Free. Unlimited test checks. Upgrade when volume grows.
Domain ownership proof
Live keys unlock only after DNS verification — ownership, not trust-on-add.
Watch after signup
Exposure monitoring for users who already got in, with optional signed alerts.
Explainable risk
Enough detail for security and support to act — without a public detection playbook.
You keep enforcement
Recommendations say allow / challenge / shadow / block. No forced CAPTCHA wall.

Not only a device ID
If all you need is a sticky visitor identifier, a pure fingerprint vendor may fit better.
