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

1 finding 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"

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

The company holds a strong market position as one of the largest building materials providers worldwide. Its business model focuses on manufacturing and distributing essential construction materials with a growing emphasis on sustainability and digital services. The website highlights strategic initiatives such as carbon capture projects and digital transformation, indicating forward-looking growth and innovation. Investor relations and compliance information are prominently featured, supporting transparency. The company leverages partnerships and dedicated product sites to enhance its ecosystem. The absence of direct contact emails and phone numbers suggests a preference for controlled communication channels, likely via contact forms and social media.

Security posture

Heidelberg Materials demonstrates a solid security foundation with HTTPS enforcement and use of Cloudflare Bot Management cookies. The presence of a cookie consent banner and privacy policy indicates GDPR compliance efforts. However, the site lacks visible security.txt or vulnerability disclosure policies, and no incident response contacts are published, which are areas for improvement. Security headers are not explicitly confirmed in the HTML, and no vulnerabilities were detected in the provided content. Overall, the security posture is good but could be enhanced with more explicit security documentation and contact channels.

Recommendations

  1. Publish explicit security headers such as X-Frame-Options and X-Content-Type-Options to enhance protection against common web attacks.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  3. Provide clear incident response contact information, including dedicated security or abuse email addresses.
  4. Enhance transparency regarding security frameworks or certifications to build trust with stakeholders.
  5. Regularly audit and update third-party scripts and cookies to ensure compliance with privacy regulations and minimize tracking risks.

Technical notes

Notes

The website is built on Drupal 11, utilizing modern frontend technologies including Tailwind CSS and JavaScript modules. It integrates third-party analytics (Etracker) and cookie consent management (2B-Advice). The site is mobile-optimized with responsive design and accessibility features. Performance is moderate, with preloading of fonts and stylesheets to improve load times. Hosting details are not explicit, but Cloudflare services are implied by cookies. The technical implementation is robust, supporting a professional and user-friendly experience. Opportunities exist to improve security header visibility and to document technical security practices more explicitly.
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.
