Technically, the site is built on Drupal 10 with modern web technologies, optimized for performance and mobile responsiveness.

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 operates in the manufacturing sector with a focus on sustainable construction materials. It holds a strong market position as one of the world's largest building materials companies. The business model includes product manufacturing and digital services to enhance customer experience. The website's investor relations section indicates transparency and engagement with shareholders. The company maintains a global presence with multiple language versions of the site. Partnerships or subsidiaries are not explicitly listed. Growth is driven by sustainability innovation and digital transformation.

Security posture

The website enforces HTTPS and uses cookie consent management, indicating compliance with privacy regulations. Security headers are implied but not explicitly confirmed. No direct security or incident response contacts or vulnerability disclosure pages were found, which could be improved. The presence of Cloudflare Bot Management cookies suggests protection against automated threats. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is good but could benefit from more transparency on security policies and contacts.

Recommendations

  1. Explicitly publish and link to security policies and incident response procedures.
  2. Add a vulnerability disclosure or security.txt file to facilitate responsible reporting.
  3. Confirm and implement comprehensive security headers such as CSP, X-Frame-Options, and X-Content-Type-Options.
  4. Provide direct security contact information or dedicated abuse/security email addresses.
  5. Maintain transparency on data retention policies and enhance privacy compliance disclosures.

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.
