Security score

66/100

Risk levelMedium

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

Sedo GmbH operates a domain parking service that enables domain owners to monetize unused domain names by displaying relevant advertisements. The website serves as an informational page explaining domain parking benefits and provides an example parked domain. The company is established since 1999 and is positioned as a recognized player in the domain monetization industry. The technical infrastructure is basic, utilizing Bootstrap CSS for layout and styling, with no detected advanced frameworks or CMS. The site is mobile responsive at a basic level and has moderate performance. Security posture is minimal with no HTTPS confirmation or security headers detected in the provided data, and no privacy or cookie policies are present, indicating compliance gaps. No contact or incident response information is provided, limiting user trust and transparency. Overall, the website is functional but lacks comprehensive security and privacy features.

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

6 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…
  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 GmbH targets domain owners who want to monetize their unused domains through parking services. The business model relies on generating revenue from advertisement clicks on parked domains. The company has a medium-sized presence in the technology sector, specifically in domain services. The website content is basic but consistent with the company's branding and market positioning. There is no evidence of partnerships or subsidiaries linked from the site. The lack of contact information and policies may impact customer trust and limit business growth opportunities. The company benefits from its long-standing market presence since 1999, but digital maturity could be improved.

Security posture

The current security posture is minimal. There is no evidence of HTTPS enforcement or security headers such as Content-Security-Policy or Strict-Transport-Security. No vulnerability disclosure or incident response information is provided. The absence of privacy and cookie policies indicates non-compliance with GDPR and related regulations. No forms or data collection mechanisms reduce attack surface but also limit user engagement. The site does not appear to use analytics or tracking scripts, which reduces privacy risks but also limits business intelligence. Overall, the security maturity is low, and improvements are needed to enhance trust and compliance.

Recommendations

  1. Implement HTTPS across the entire website and enforce secure connections.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and inform users.
  3. Publish contact information including security incident response contacts to improve transparency.
  4. Deploy security headers to protect against common web vulnerabilities.
  5. Consider adding a vulnerability disclosure policy and security.txt file to encourage responsible reporting.

Technical notes

Notes

The website uses Bootstrap CSS for responsive design but lacks advanced frameworks or CMS platforms. The HTML structure is valid but minimal, with no scripts or analytics detected. Performance is moderate with basic mobile optimization. The site does not implement SEO best practices beyond basic meta tags. There is no evidence of modern JavaScript frameworks or content management systems. Hosting provider and SSL configuration details are not provided, limiting deeper technical assessment. The site could benefit from modernization and enhanced accessibility features.
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.
