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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

HORNBACH holds a strong market position as a major retail chain in the home improvement sector, leveraging both e-commerce and physical stores. Its business model focuses on providing a wide product range at competitive prices with value-added services like project consulting. The company benefits from a well-established brand and a broad customer base including DIY enthusiasts and professionals. Partnerships with technology providers for analytics and consent management enhance its digital capabilities. The company’s growth is supported by continuous content updates, project ideas, and localized market information.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and integration of consent management for privacy compliance. No critical vulnerabilities or exposed sensitive data were detected in the analysis. However, the absence of a publicly accessible security policy or incident response contact limits transparency. The use of third-party scripts is managed but requires ongoing monitoring to mitigate supply chain risks. Overall, the security measures align well with industry best practices for retail e-commerce platforms.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and user guidance.
  2. Provide clear incident response contact channels such as security@ or abuse@ emails.
  3. Regularly audit and update third-party scripts to reduce vulnerability exposure.
  4. Enhance security headers with additional directives like Expect-CT and Feature-Policy.
  5. Maintain transparency on data retention policies and update privacy notices accordingly.

Technical notes

Notes

The website is built on a modern JavaScript stack using StencilJS components, integrated with Usercentrics for consent management and Dynatrace for real user monitoring. It leverages Coveo for search analytics and Google Tag Manager for marketing tags. The site is hosted with EuroDNS nameservers and uses optimized fonts and preloading strategies for performance. Mobile optimization and accessibility are well implemented, contributing to a fast and user-friendly experience. The technical infrastructure supports scalability and compliance but should continue evolving to address emerging security and privacy requirements.
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.
