Low risk. 3 critical or high findings in Security headers and GDPR outside view.

Security score

78/100

Risk levelLow

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

The website is a domain sales landing page hosted on Sedo.com, a well-established domain marketplace platform with over 26 years of experience. The page offers the domain greenfence.eu for sale with clear pricing and purchase options. The business model focuses on domain brokerage and transfer services targeting domain buyers and sellers globally. The technical infrastructure leverages modern JavaScript frameworks (likely Vue.js) and is hosted behind Cloudflare, ensuring moderate performance and mobile optimization. Security posture is adequate with HTTPS and cookie consent mechanisms but lacks explicit security headers and published security policies. Privacy compliance is basic with no visible privacy or terms of service documents on this page. Overall, the website is functional and trustworthy for its purpose but could improve transparency and security documentation.

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

3 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

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

    • 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

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

Sedo.com operates as a domain marketplace with a strong market position supported by decades of experience and a high volume of domain transfers monthly. Its revenue streams derive from domain sales commissions and transfer services. The target customers are domain investors, businesses, and individuals seeking domain names. The platform supports multiple languages and payment methods, enhancing its global reach. The business ecosystem includes secure payment processing and personal assistance, reinforcing customer trust. However, the specific domain seller's business details are not disclosed, limiting deeper business intelligence on greenfence.eu itself.

Security posture

The security maturity level is moderate. The site uses HTTPS and implements a cookie consent banner indicating GDPR awareness. However, it lacks visible security headers such as Content Security Policy or HSTS, and no incident response or vulnerability disclosure information is provided. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of explicit security policies and certifications suggests room for improvement in security transparency and compliance. Incident response readiness cannot be assessed from the available data.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service on the domain sales pages.
  2. Add security headers like Content Security Policy, HSTS, and X-Frame-Options to enhance protection.
  3. Publish a vulnerability disclosure policy or security.txt file to improve security transparency.
  4. Provide explicit incident response contact channels such as security@ or abuse@ email addresses.
  5. Enhance accessibility and SEO optimization to improve user experience and search visibility.

Technical notes

Notes

The website uses a modern JavaScript framework (likely Vue.js) with modular CSS and JavaScript assets loaded from Sedo's CDN. Google Tag Manager and Google Analytics are integrated for tracking and marketing purposes. Hosting is behind Cloudflare, providing performance and security benefits. The page is mobile optimized with responsive design elements. However, no CMS is detected, and the site could benefit from improved accessibility features and SEO metadata. Performance is moderate with no obvious blocking scripts or errors. Technical debt appears low but could be improved with better security header implementation.
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.
