Trustcaptcha (by Trustcaptcha GmbH in Munich) provides a privacy-first CAPTCHA platform for websites. It operates invisible CAPTCHA challenges (proof-of-work, bot scoring) to block automated traffic without visible puzzles. The service is fully GDPR-compliant and is hosted entirely in the EU (German data centers) to ensure data sovereignty. It also emphasizes accessibility compliance (WCAG) and states it does not use external tracking or cookies. Trustcaptcha is intended as an alternative to centralized CAPTCHA services like reCAPTCHA, giving businesses control over data. The site provides technical and legal detail but no founding year is listed.
