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. 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

  2. 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

      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

      • ASVS V3.4.3

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

Hugendubel maintains a strong market position as a large-scale retailer in the book and media sector, with a diversified product catalog and a well-structured online presence. The business model focuses on direct e-commerce sales complemented by physical store services. The company benefits from brand longevity and a broad target audience. While no parent or subsidiary companies were identified, the site integrates with multiple external services for analytics, marketing, and accessibility. Growth indicators include extensive category offerings and modern digital marketing tools. Strategic partnerships appear limited to service providers rather than business alliances.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and no detected vulnerabilities in the client-side code. The use of Usercentrics CMP indicates GDPR compliance efforts. However, the absence of published security policies, incident response procedures, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. No direct security contact channels were found, which could hinder timely incident reporting. Overall, the security culture appears solid but could benefit from enhanced communication and formalized policies.

Recommendations

  1. Publish a dedicated security policy and incident response plan accessible on the website.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide direct security contact emails such as security@ or abuse@ for incident reporting.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance transparency on data retention and privacy practices to strengthen GDPR compliance.

Technical notes

Notes

The website is built on a modern React-based framework (Next.js) with server-side rendering capabilities, ensuring good SEO and performance. Integration of Usercentrics CMP and digiAccess accessibility tools demonstrates commitment to privacy and accessibility standards. The presence of multiple preloaded fonts and scripts indicates optimization efforts, though performance is moderate likely due to extensive content and third-party integrations. Mobile optimization and accessibility features are excellent, supporting a wide user base. Hosting details are not explicit, but the domain uses stable name servers. Technical risks are minimal, with opportunities for further performance tuning and enhanced security transparency.
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.
