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

MediaMarkt is a leading German consumer electronics retailer with a strong market presence in Germany and Europe. The company operates both physical stores and an online platform offering a wide range of electronic products and related services. The website analyzed is currently inaccessible due to a Cloudflare security challenge page, which prevents direct access to the main content and business information. This limits the ability to fully assess the website's technical and security posture. Technically, the site uses Cloudflare's WAF and Akamai DNS services, indicating a mature infrastructure designed to protect against attacks and ensure availability. However, the presence of a security challenge page without visible privacy, cookie, or contact information reduces transparency and user experience. No analytics or marketing scripts were detected beyond the security challenge mechanisms. From a security perspective, the site benefits from enterprise-grade DNS and WAF protection but lacks visible security headers or policies on the challenge page. The absence of accessible privacy and cookie policies and contact information limits compliance assessment. The domain WHOIS data is consistent with a legitimate enterprise, showing no suspicious patterns. Overall, the website's risk is low given the brand and infrastructure, but the current blocking by Cloudflare WAF significantly restricts analysis and user access. Strategic recommendations include allowing access to main content for analysis, publishing clear privacy and cookie policies, and improving transparency to enhance trust and compliance.

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.

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 · found on this site
  • 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

MediaMarkt holds a strong market position as a top electronics retailer in Germany and Europe, leveraging both physical retail and e-commerce channels. Its business model focuses on consumer electronics sales with additional in-store services. The company targets general consumers seeking electronics products. The use of Akamai DNS and Cloudflare WAF indicates investment in robust infrastructure. The lack of visible contact or policy information on the challenge page suggests the need for improved digital transparency. No direct partnerships or subsidiaries were identified from the limited data. The brand is well-known, but the website's current access restrictions may impact customer experience and trust.

Security posture

The website employs Cloudflare's security challenge and Akamai DNS, reflecting a high-security maturity level in infrastructure. However, the blocking of content by the WAF challenge page prevents verification of security headers, SSL configuration, and secure data handling practices. No exposed vulnerabilities or sensitive data were detected, but the absence of visible privacy and cookie policies and contact channels for incident response indicates compliance gaps. The site lacks a visible vulnerability disclosure or security.txt file. Incident response readiness cannot be assessed due to limited access. Overall, the security posture is strong at the infrastructure level but lacks transparency and user-facing security assurances.

Recommendations

  1. Allow direct access to the main website content to enable comprehensive security and compliance analysis.
  2. Publish clear and accessible privacy and cookie policies on the website's landing pages.
  3. Implement visible security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear contact information including security incident response channels (e.g., security@ or abuse@ emails).
  5. Consider adding a vulnerability disclosure policy or security.txt file to improve transparency and trust.
Site observations

Automated reading of the public site. Ratings are indicative.

Cloudflare detected. The page is a Cloudflare security challenge page with Turnstile captcha, blocking direct access to main content. These observations may be incomplete. For a fuller analysis, contact guard@offseq.com.

Technical notes

Notes

The website uses Cloudflare for WAF and CDN services and Akamai for DNS, indicating a modern and robust technical infrastructure. The presence of Cloudflare Turnstile captcha scripts confirms active bot mitigation measures. The HTML content is minimal and serves only as a security challenge page, lacking typical website elements such as metadata, structured data, or SEO tags. No CMS or frameworks are detectable from the limited content. Performance and mobile optimization cannot be assessed due to content blocking. The technical setup prioritizes security but at the cost of accessibility and user experience.
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.
