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

Hartmann Holzbau GmbH & Co. KG is a well-established family-owned company specializing in ecological timber construction with over 100 years of tradition in the Hessen region of Germany. The company offers a range of services including house building, timber construction, renovations, and engineering timber works, focusing on sustainable and regional building practices. Their website reflects a professional and consistent brand image with clear contact information and multiple certifications that reinforce their market credibility. Technically, the website is built on TYPO3 CMS with modern front-end libraries such as jQuery, Owl Carousel, and Bootstrap, providing a responsive and user-friendly experience. The site is well-structured with good SEO practices and mobile optimization, although some accessibility features could be improved. No advanced analytics or tracking scripts were detected, indicating a privacy-conscious approach. From a security perspective, the website uses HTTPS with a good SSL configuration but lacks important security headers and a cookie consent mechanism, which are recommended for GDPR compliance and enhanced security. There is no visible incident response or vulnerability disclosure information, which could be improved to strengthen trust and preparedness. Overall, the website presents a trustworthy and professional image with solid business credibility and technical implementation. Strategic improvements in privacy compliance and security policies would further enhance their security posture and regulatory adherence.

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

7 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

      Prevents clickjacking attacks

      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

      What to do: Implement a Content-Security-Policy appropriate for your application

      • 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

Hartmann Holzbau operates in the ecological timber construction sector, targeting residential and commercial clients in the Hessen region. Their competitive advantage lies in their long-standing tradition, regional sourcing of materials, and multiple quality certifications. The business model focuses on sustainable construction practices, combining modern technology with traditional craftsmanship. The company maintains a strong regional presence with projects within approximately 100 km radius, emphasizing environmental responsibility and social values. The website supports their market position by showcasing certifications and providing clear contact channels, although it lacks detailed terms of service or privacy mechanisms that could support further business transparency.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and no visible exposure of sensitive data. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap in defense-in-depth strategies. The lack of a cookie consent mechanism and incident response contact information indicates incomplete GDPR compliance and limited readiness for security incidents. No vulnerable or outdated libraries were detected, and no forms with insecure inputs were found on the main page. Overall, the security posture is adequate but could be significantly improved by implementing recommended headers, privacy controls, and incident response disclosures.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a cookie consent banner and detailed cookie policy to comply fully with GDPR requirements.
  3. Publish an incident response contact or security email address to improve transparency and readiness for security issues.
  4. Consider creating and publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance accessibility features to improve usability for all users and meet WCAG guidelines.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and widely used content management system, combined with front-end technologies such as jQuery, Owl Carousel for sliders, LightGallery for image galleries, and Bootstrap for responsive design. The site loads multiple CSS and JS assets from its own domain, indicating self-hosted resources. Performance is moderate with autoplay sliders and image galleries, but no heavy third-party analytics or advertising scripts were detected, which benefits load times and privacy. The site is mobile optimized and SEO-friendly with proper meta tags and Open Graph data. Hosting provider details are not explicitly available from the content. There is room for improvement in accessibility and security header implementation.
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.
