About Edge Shield
Edge Shield is a privacy-first, invisible CAPTCHA alternative that scores every visitor from 1–100 so you can allow, step-up, redirect, or block traffic without puzzles or tracking. Integration is a single script tag and a sitekey div; a lightweight proof-of-work runs in a background thread while risk signals are scored. Server-side validation uses a single API call returning a pass/fail plus a 1–100 humanity score. Tokens are single-use and expire in five minutes. Core protection is free forever, with no cookies, no fingerprint database, and GDPR/CCPA-friendly defaults.
