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.

The CAPTCHA is fully customizable

Theme
You can set the light or dark mode or activate the auto detection mode.
Custom Translation
You can add more languages and override existing CAPTCHA translations with your own texts.
Language
The CAPTCHA supports over 35 different languages. You can set a specific language or use the auto detection mode.
Branding & Privacy
You can hide our branding and you can set a custom privacy link.
Width
You can set the width of the CAPTCHA.
