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

HORNBACH Baumarkt AG operates a leading home improvement retail and e-commerce platform primarily serving the German market and other European countries. The website offers a comprehensive product catalog exceeding 500,000 items, project planning resources, and professional services, positioning itself as a top-tier DIY and construction materials provider. The company is well-established with a long history dating back to 1877 and operates under the HORNBACH Holding AG & Co. KGaA umbrella. Technically, the website employs modern web technologies including Stencil.js for web components, Usercentrics for consent management, and Dynatrace for real user monitoring, indicating a mature digital infrastructure. The site is optimized for performance, mobile responsiveness, and accessibility, with strong SEO practices and structured data enhancing discoverability. Security posture is robust with enforced HTTPS, comprehensive security headers, and GDPR-compliant consent mechanisms. However, the absence of a dedicated security policy or incident response contact page suggests room for improvement in transparency and readiness. No vulnerabilities or suspicious activities were detected. Overall, the website reflects a professional, trustworthy, and secure online presence suitable for an enterprise-level retail business. Strategic enhancements in security communication and incident response disclosures would further strengthen stakeholder confidence.

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 leading DIY and home improvement retailer in Germany and Europe. Its business model combines brick-and-mortar stores with a sophisticated e-commerce platform, targeting both consumers and professional builders. Revenue streams include product sales, project consulting, and professional services. The company maintains a broad partnership ecosystem, including authentication and analytics service providers. Growth indicators include extensive project content and multi-market presence. The website's comprehensive navigation and content reflect a customer-centric approach, supporting diverse customer segments from DIY enthusiasts to professionals.

Security posture

The website demonstrates a mature security posture with HTTPS enforcement, strong security headers, and GDPR-compliant consent management via Usercentrics. The use of secure cookies with appropriate SameSite attributes and content security policies reduces common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected. However, the lack of a published security policy and incident response contact information limits transparency and may impact incident handling efficiency. No vulnerability disclosure program or security.txt file was found, which could be considered for future improvements to engage security researchers and enhance trust.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance transparency around data retention policies and user privacy beyond GDPR compliance.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy and security risks.

Technical notes

Notes

The website is built on a modern technology stack leveraging Stencil.js for modular web components, ensuring maintainability and performance. Integration with Usercentrics enables robust consent management aligned with GDPR requirements. Dynatrace and Coveo analytics provide comprehensive monitoring and search analytics capabilities. Hosting is managed via EuroDNS nameservers, indicating a professional DNS setup. The site is optimized for fast loading and mobile responsiveness, with accessibility considerations evident in ARIA roles and semantic HTML. Technical risks are minimal, but continuous monitoring of third-party dependencies is advised to mitigate supply chain risks.
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.
