TrustCaptcha offers maximum security and reliability

CAPTCHA Demo

This is what a form with TrustCaptcha could look like.

1
Dynamically Scaled Proof-of-WorkTo make your website unattractive to bots and unprofitable for attacks, TrustCaptcha uses a dynamically scaled proof-of-work cryptographic puzzle that is automatically solved, growing tougher with each repeated request.
2
Individual AI-based Bot ScoreThe bot score detects and identifies bots. Algorithms and AI analyse device data, session information and user behaviour to calculate a probability value — the bot score. It’s comparable to the Google reCAPTCHA score.
3
Custom Security ConfigurationWith our powerful security configuration options, you can customise the CAPTCHA exactly to your security requirements.
