TrustCaptcha for DotNet

Protect websites and apps against bots and spam with a privacy-first, EU-hosted CAPTCHA solution.

⚠️ DEPRECATED
This package has been renamed and is now maintained as TrustComponent.TrustCaptcha (version 2.0.0 or above).

What is TrustCaptcha?

TrustCaptcha combines proof-of-work, an AI bot-score and custom security rules to stop automated bot abuse — without image marking or puzzles

Key perks:

  • Privacy-friendly & GDPR-compliant – data processed exclusively in Europe
  • No visual challenges – users never label images or solve quizzes
  • Fully themable widget – matches any brand and design and improves your user flow
  • Conversion-safe – near-zero user drop-off compared to legacy CAPTCHAs

Read the full TrustCaptcha product overview for technical details and the security concept.

Get started

  1. Create an account: sign up / sign in.
  2. Choose a CAPTCHA: pick an existing one or create a new one.
  3. Embed the widget: implement the TrustCaptcha widget into your website or app.
  4. Validate result: validate the CAPTCHA verification result in your backend.
