Privacy-first CAPTCHA for European businesses
Four 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, a built-in honeypot that catches spam bots, and Security Rules you control. The result is bot protection without puzzles or cookies that your users barely notice.
Verifies automatically — no clicks, no puzzles.
Trusted by companies, organisations and governments.





What makes TrustCaptcha different?
Proof-of-Work plus real bot detection.
Most European CAPTCHA alternatives rely solely on Proof-of-Work. They slow bots down, but can't tell them apart from humans. TrustCaptcha adds bot detection, a honeypot and security rules on top, so it can.
Attack Prevention
Dynamic Proof-of-Work makes mass attacks expensive to run, while real users barely notice it.
Learn more →Bot Detection
Risk scoring rates every request in real time, much like the reCAPTCHA score, and flags bots, spam and attackers.
Learn more →Built-in Honeypot
Invisible trap fields catch form-spam bots. They need no setup, and visitors never see them.
Learn more →Security Rules
Custom access rules, geoblocking, bypass keys and Proof-of-Work tuning, so you decide who gets through.
Learn more →Few European CAPTCHAs combine proof-of-work with real-time risk analysis, a honeypot and custom security rules. TrustCaptcha brings them together in one anti-bot service, and it is a GDPR-compliant CAPTCHA that sets no cookies.
How it works
Stop bots without users noticing.
User interaction
A user interacts with a protected part of your website by opening a form, signing in, or clicking the CAPTCHA.
Invisible verification
Bot detection and proof-of-work run silently in the background with no clicks and no puzzles, finishing before the user submits the form.
Users pass, threats don't
Real users continue uninterrupted, while bots and attackers are slowed down by proof-of-work and flagged by their bot score.
Optimized widget
A widget your users will love
On-brand and built to feel like a native part of your product.
- Full design control — from the Team plan, fine-tune colors, borders, corner radius, border width and the checkbox.
- Light & dark mode — switch between light and dark themes, or auto-detect the user's system preference.
- Remove logo — with the Captcha Branding add-on, hide the TrustCaptcha logo so the widget carries only your brand.
- Unlimited languages — 37+ languages built in, with automatic language detection, and any other language can be added.
- Customizable text — every visible label, ARIA label, and screen-reader text can be tailored to your wording.
- Native on every screen — adapts to phones, tablets and desktops and fits into your layout.
- Fully invisible mode — with the same add-on, verification runs with no visible widget at all.
- WCAG & EAA aligned — designed to meet WCAG 2.2 and the European Accessibility Act, so the estimated 1.3 billion people with a significant disability can get through your forms.
Verification
Verification users won't even notice
Humans get no task to solve. Bots, including AI-driven ones, are scored and slowed down.
- Invisible to visitors — no puzzles, no image grids, no challenges. Verification runs in the background while visitors get on with what they came for.
- Autostart — verification starts in the background as soon as the form loads and is usually finished before visitors hit submit.
- Fast for real users — for legitimate visitors, verification usually completes within a few seconds.
- Four security mechanisms in one — attack prevention, bot detection, a built-in honeypot and customizable security rules combined into a single CAPTCHA.
- Resistant to AI-driven bots — signal analysis and bot scoring catch AI agents that get through puzzle CAPTCHAs with ease.
- Built-in honeypot — invisible to visitors, it adds one more layer that catches form-spam bots.
- Cookie-free — TrustCaptcha sets no cookies, so nothing is stored in your visitors' browsers for the CAPTCHA.
- EU-only hosting — all data is processed and stored exclusively in the EU on ISO 27001-certified infrastructure, with no transfers to third countries.
Platform
A platform built around how you work
Settings, analytics, audit logs and team access for the people who run bot protection day to day, from one website to many.
- Ready out of the box — every option comes preconfigured for typical use cases and devices. Most teams launch with the defaults and fine-tune later.
- Multiple environments — fully isolated staging, production, and development setups with their own settings, rules, and credentials.
- Real-time analytics — verification volumes, bot score distributions, device data, and regional traffic patterns at a glance.
- Verification insights — see every step of a verification, including captured data, access decisions, and the reasoning behind every risk score.
- Audit logs — a complete trail of every action on your account: who did what, when and on which object, kept 30 days on Team and 90 days on Enterprise, longer on a custom plan.
- Data exports — pull verification data, analytics, and audit logs as CSV, Excel, or JSON whenever you need them.
- Users & roles — roles such as Admin, Member, Billing or Auditor, view-only access without a role, plus SSO with OIDC or SAML and enforced two-factor authentication for the whole team.
- Bypass keys — skip verification entirely in trusted contexts, such as CI/CD end-to-end tests or internal tools.
- Engineer-led support — real engineers help with integration, migration, agency workflows, procurement, and health checks.

| Your question | Feature | What it does |
|---|---|---|

| Catch simple form bots? | Built-in honeypot | A hidden field that people never see and bots fill in. |
| Block countries, IP ranges or devices? | Security rules | Rules on IP, country, language, time zone, browser and device that allow or block a request. |
| Keep visitor data in the EU? | EU hosting without cookies | Processing in EU data centers, no cookies and a DPA for every customer. |
| Let everyone through, screen reader users too? | Accessibility | No puzzle and no time limit, with ARIA labels and screen-reader text, designed to meet WCAG and the European Accessibility Act. |
| Match the widget to my brand? | Widget design | Colors, borders, light and dark themes, and your own texts in 37+ languages. |
| Test safely before going live? | Environments | Separate environments for development, staging and production. |
| Show auditors who changed what? | Audit logs | Every change to your settings with who, what and when, ready to export. |
