HORNBACH Baumarkt AG operates a leading hobby and home improvement e-commerce platform in the Czech Republic, complemented by physical stores such as the Praha - Černý Most location. The website targets both DIY enthusiasts and professional customers, offering a wide range of products from flooring to garden supplies and hardware. The company maintains a strong market position with consistent branding and a comprehensive online presence including social media and project advice content. Technically, the website leverages modern web technologies including Spryker e-commerce platform, Usercentrics for consent management, and OIDC for authentication, ensuring a robust and user-friendly experience. Security posture is strong with HTTPS enforcement, security headers, and cookie consent mechanisms, though public security policies and incident response contacts are not prominently disclosed.

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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube, Google Ads

      What to do: Document all third-party data sharing in your privacy policy

  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 X-Frame-Options header

      Prevents clickjacking attacks

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

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's business model focuses on retail sales of home improvement products through both online and offline channels. The company targets a broad audience including hobbyists and professionals, providing extensive product assortments and project planning resources. The presence of multiple sister domains across Europe indicates a large multinational footprint. The website's integration with marketing and analytics tools such as Google Ads and Dynatrace supports data-driven growth strategies. The company also invests in user experience and mobile optimization, enhancing customer engagement. Strategic partnerships and a strong brand identity contribute to competitive advantages in the retail sector.

Security posture

The website exhibits a solid security foundation with HTTPS, Content Security Policy, and other security headers implemented. The use of Usercentrics CMP ensures GDPR-compliant cookie management. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of a publicly accessible security policy, incident response contacts, and vulnerability disclosure mechanisms represents a gap in transparency and readiness. Enhancing these areas would improve trust and preparedness for security incidents. Overall, the security posture is good but could benefit from formalized policies and disclosures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, including security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance user input validation and monitoring to prevent injection and other common web attacks.

Technical notes

Notes

The website is built on a modern e-commerce platform (Spryker) with custom CMS components using StencilJS. It employs asynchronous loading of scripts, lazy loading of images, and preloading of fonts to optimize performance. The site is mobile-optimized and accessible, with semantic HTML and ARIA attributes. Integration with OIDC for authentication and Usercentrics for consent management demonstrates advanced digital maturity. Performance is moderate with room for improvement in hosting and caching strategies. The technical stack is robust and supports scalability and security, though hosting provider details are not disclosed.
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.
