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

Captcha.eu is a technology company specializing in GDPR-compliant bot protection solutions, positioning itself as a privacy-focused alternative to traditional services like reCAPTCHA. The website targets developers and website owners who require bot and spam protection while adhering to strict European data protection regulations. The business model is SaaS-based, offering bot protection technology emphasizing compliance and user privacy. The company maintains a consistent brand presence with good content quality and clear messaging about its services. Technically, the website is built on WordPress with a modern plugin ecosystem including Yoast SEO, TranslatePress for multilingual support, and Google Site Kit for analytics integration. The site demonstrates good mobile optimization and moderate performance. Security best practices are observed with HTTPS enforcement and multiple security headers, though there is room for improvement in publishing explicit security policies and incident response information. The security posture is strong with no visible vulnerabilities or exposed sensitive data. The site implements GDPR-compliant cookie consent mechanisms and respects user privacy. However, the lack of publicly available WHOIS data due to privacy protection limits domain registration transparency, though this aligns with the company's privacy emphasis. Overall, the site is trustworthy, professional, and compliant with relevant privacy regulations. Strategic recommendations include publishing a dedicated security policy and incident response page, implementing a vulnerability disclosure program, enhancing accessibility features, and conducting regular audits of third-party scripts to maintain security integrity.

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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Business profile

Captcha.eu operates in the niche market of privacy-compliant bot protection, leveraging GDPR compliance as a competitive advantage. Its business model focuses on SaaS delivery of bot protection technology, targeting European and global website operators concerned with privacy regulations. The company benefits from a clear market positioning emphasizing privacy and compliance, which is increasingly important in the EU and beyond. The presence of multilingual support indicates an intent to serve a broad European audience. The company maintains a partnership or service relationship with captcha.at domains, suggesting a regional or technical collaboration. Revenue streams likely include subscription fees for bot protection services. The company’s ecosystem includes integrations with popular CMS platforms like WordPress, enhancing market reach. Growth indicators include active content updates and SEO optimization. Strategic observations suggest continued focus on privacy and compliance will sustain competitive differentiation.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented, including Content-Security-Policy and Strict-Transport-Security. No exposed sensitive information or vulnerable libraries were detected in the HTML content. The cookie consent mechanism is GDPR compliant, indicating attention to privacy regulations. However, the absence of a dedicated security policy or incident response contact limits transparency in security governance. There is no evidence of a vulnerability disclosure program or security.txt file, which are recommended best practices. The use of third-party scripts such as Google Tag Manager and Privacy Center SDK is noted; regular audits of these components are advisable to mitigate supply chain risks. Overall, the security culture appears positive but could be enhanced by formalizing policies and response procedures.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and controls.
  2. Establish and publicize an incident response contact channel for security issues.
  3. Implement a vulnerability disclosure program and consider adding a security.txt file.
  4. Enhance website accessibility to improve compliance and user experience.
  5. Regularly audit third-party scripts and plugins to identify and mitigate vulnerabilities.

Technical notes

Notes

The website is built on WordPress 6.8.3, utilizing a suite of plugins for SEO (Yoast SEO Premium), multilingual support (TranslatePress), and performance optimization (Google Site Kit). The tech stack includes custom SDKs for captcha.eu and privacy-center.org, indicating integration with privacy and bot protection services. The site uses modern CSS and JavaScript, with responsive design elements for mobile optimization. Performance is moderate, with lazy loading for images and content visibility optimizations. The hosting provider is not explicitly identified. Technical risks include reliance on multiple third-party scripts which require ongoing security monitoring. The site’s SEO is well-implemented with proper meta tags, Open Graph, and JSON-LD structured data enhancing search engine visibility. Overall, the technical infrastructure is solid with opportunities for further optimization and security hardening.
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.
