Friendly Captcha employs a fundamentally new approach to securely defend your websites from spam and bots. It is easy to use and respects your user’s privacy.


Bots and spam are increasingly spreading on the Internet.

Every day, hackers around the world try to use bots to automatically attack websites. To ensure the availability of your website and protect your business, you need intelligent protection mechanisms like CAPTCHA systems.
