What it is
A bot detection service that sits between websites and their visitors, using proprietary threat signatures to identify automated traffic across IP clusters. Built as an alternative to Google's reCAPTCHA with a privacy-first architecture that doesn't track users across sites. The typical implementer is a security engineer or web developer protecting login forms, registration pages, or comment sections from spam and credential stuffing attacks.
