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

2 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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 holds a strong position in the domain marketplace sector, offering domain sales, parking, and brokerage services. Its business model revolves around monetizing premium domain names and providing a platform for domain investors and buyers. The company targets a global audience of domain investors and businesses. The domain's registration with World4You Internet Services GmbH, a reputable Austrian registrar, supports the business's legitimacy. The website's content is minimal, focusing on domain availability and purchase options, which is typical for domain sales landing pages. The lack of detailed business contact information and policies on this page suggests that more comprehensive information may be available elsewhere on the main site. Sedo's use of Cloudflare DNS and transfer protection status enhances its operational security and trust signals.

Security posture

The website benefits from HTTPS encryption and domain transfer protection, which are fundamental security measures. However, the absence of DNSSEC reduces DNS security robustness. No security headers such as Content-Security-Policy or X-Frame-Options were detected, which could expose the site to certain web-based attacks. The cookie consent mechanism indicates some attention to privacy compliance, but the lack of explicit privacy and security policies limits transparency. No vulnerabilities or exposed sensitive data were identified in the provided content. Overall, the security posture is moderate but could be enhanced by enabling DNSSEC, adding security headers, and publishing clear security and incident response policies.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and terms of service policies.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear contact information including security incident response contacts.
  5. Enhance website content quality and navigation to improve user experience and trust.

Technical notes

Notes

The website uses modern web technologies including ES modules for JavaScript and Cloudflare for DNS hosting, which supports good performance and security. The CSS and font usage indicate a focus on consistent branding and responsive design. However, the site lacks advanced frameworks or CMS indications, suggesting a custom or lightweight implementation. Performance is moderate with room for optimization. Accessibility and SEO features are basic, with no explicit ARIA roles or advanced metadata detected. The domain is hosted by World4You Internet Services GmbH, a reputable provider. Overall, the technical infrastructure is solid but could benefit from enhanced SEO, accessibility, and security 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.
