TrustCaptcha

Privacy-first CAPTCHA for European businesses

Three layers of defense in one CAPTCHA: a real-time Bot Score that identifies risk, adaptive Proof-of-Work that stops attacks before they reach you, and Security Rules you control. Verifies automatically — no clicks, no puzzles. Trusted by companies, organisations and governments. Most European CAPTCHA alternatives rely solely on Proof-of-Work — they slow bots down, but can't tell them apart from humans. Dynamic Proof-of-Work makes mass attacks computationally prohibitive while staying instant for real users.
