Hcaptcha

hCaptcha is a bot-detection and human-verification service that website owners embed to distinguish genuine users from automated traffic. It presents challenges such as image selection puzzles to visitors during logins, form submissions, or checkout processes, blocking spam, credential stuffing, and scraping attempts. The service is designed for website operators, publishers, and enterprises seeking an alternative to traditional CAPTCHA providers, often as a drop-in replacement compatible with existing integrations. Beyond basic bot filtering, hCaptcha offers an Enterprise tier with adaptive risk scoring, detailed analytics, and configurable difficulty levels to address more sophisticated automated threats. The company also historically enabled site owners to earn revenue by having users label data through its challenges, linking security verification with machine learning data annotation.
