hCaptcha is the world's most widely used independent CAPTCHA service.
hCaptcha brings a modern, privacy-focused approach to stopping bots.
We show CAPTCHA challenges that are difficult for bots but easy for people by collecting difficult-to-label data from machine learning problems, and using it to distinguish whether a website or app visitor is human.
Bad actors are increasingly common online. But sacrificing user privacy is not the answer.
Security solutions offered by ad companies focus primarily on tracking users across the web. We have created an effective security solution that proves harming user privacy is not necessary to deliver excellent results.
