0–100, higher is better. How it is calculated

Captcha.eu is a technology company specializing in GDPR-compliant bot protection solutions designed to prevent abuse, spam, and automated attacks without compromising user privacy. Positioned as a privacy-first alternative to traditional CAPTCHA services like Google reCAPTCHA, the company offers invisible and simple widget-based verification methods integrated primarily through WordPress plugins and other platforms. Their market position is strengthened by partnerships with reputable Austrian and European organizations and a focus on compliance with European data protection regulations. Technically, the website is built on WordPress with modern SEO and multilingual support, hosted on AWS infrastructure. However, the absence of a valid SSL certificate significantly weakens the security posture, despite the presence of security headers and HSTS. Privacy compliance is strong, with no cookies or tracking and clear privacy policies, but lacks a cookie consent mechanism. Overall, the site is professional, user-friendly, and trustworthy but requires urgent improvements in SSL/TLS configuration to enhance security and user trust.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

7 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The company targets businesses requiring bot protection that complies with GDPR, emphasizing privacy and ease of integration. Their subscription-based business model includes tiered plans and custom enterprise offerings, catering to small to medium-sized businesses and larger companies. The partnership ecosystem includes notable Austrian and European entities, enhancing credibility and market reach. The company leverages WordPress as its CMS and integrates multiple plugins for SEO, multilingual support, and user engagement. Revenue streams likely derive from subscription plans and custom contracts. The company demonstrates growth potential through continuous content updates and certifications like WACA Silver. Strategic observations include a strong focus on privacy and accessibility, positioning the company well in the European market where data protection is paramount.

Security posture

The website exhibits a moderate security maturity level with several best practices such as HSTS and security headers in place. However, the critical absence of a valid SSL certificate and lack of modern TLS protocols severely undermine the security posture, exposing users to risks of data interception and trust issues. No explicit incident response or vulnerability disclosure policies are published, indicating potential gaps in security governance. The site avoids common vulnerabilities and does not expose sensitive data in the HTML. Privacy compliance is well addressed, but the lack of cookie consent mechanisms may pose regulatory risks. Overall, while the site is secure against common web vulnerabilities, the missing SSL certificate is a critical issue that must be addressed immediately.

Recommendations

  1. Obtain and install a valid SSL/TLS certificate to enable HTTPS and secure user connections.
  2. Enable modern TLS protocols (TLS 1.2 or TLS 1.3) and disable insecure protocols.
  3. Implement OCSP stapling and session resumption to improve SSL performance and security.
  4. Add a cookie consent mechanism to comply fully with GDPR cookie regulations.
  5. Publish explicit security policies including incident response and vulnerability disclosure procedures to enhance transparency and trust.
Technical notes

Notes

The website is built on a modern WordPress 6.8.1 platform with a comprehensive set of plugins including Yoast SEO Premium for SEO optimization, TranslatePress for multilingual support, and Essential Blocks for enhanced content features. Hosting is provided via Amazon AWS, indicated by DNS and nameserver data. Performance is moderate with some caching in place but no explicit load time data. Mobile optimization and accessibility are good, supported by WACA Silver certification and accessible design elements. SEO is excellent with proper meta tags, Open Graph data, and structured JSON-LD schema. The main technical risk is the lack of a valid SSL certificate and disabled TLS protocols, which impacts security and user trust.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
