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

The Verein Deutscher Zementwerke e.V. (VDZ) operates as a leading research and competence center for the cement, concrete, and environmental protection sectors in Germany. Established in 1877, it serves as a non-profit association providing technical, scientific, and economic-political services including research, certification, consulting, and training to the cement industry and related stakeholders. The website reflects a mature and professional organization with comprehensive service offerings and a strong market position in the energy and manufacturing sectors. Technically, the website is built on TYPO3 CMS, leveraging modern web technologies including SVG graphics and asynchronous JavaScript modules for enhanced user experience. It integrates Matomo analytics for privacy-conscious user tracking and implements GDPR-compliant cookie consent mechanisms. The site is mobile-optimized, accessible, and SEO-friendly, indicating a well-maintained digital infrastructure. From a security perspective, the site enforces HTTPS and employs secure form handling practices. However, it lacks explicit security policy documentation and incident response contact details, which are recommended for enhanced transparency and trust. No vulnerabilities or suspicious content were detected, and the WHOIS data aligns consistently with the website's claims, supporting legitimacy. Overall, the VDZ website demonstrates a high level of professionalism, security, and compliance suitable for its industry and audience. Strategic improvements in security policy transparency and incident response readiness would further strengthen its security posture and 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

2 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 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

  2. 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

VDZ holds a strong market position as the technical and scientific association for the German cement industry, offering a broad portfolio of services including research, certification, environmental consulting, and professional training. Its business model as a non-profit association focuses on supporting industry transformation towards sustainability and climate protection. The organization targets industry professionals, researchers, and companies involved in cement and concrete production and environmental management. The presence of subsidiaries like VDZ Service GmbH and VDZ Technology gGmbH indicates a structured ecosystem supporting certification and research activities. The website content and structure reflect a mature organization with clear growth orientation and stakeholder engagement through events, publications, and training programs.

Security posture

The website exhibits a solid security posture with HTTPS enforced and secure handling of user inputs in forms. The presence of a cookie consent banner and GDPR-compliant privacy policy indicates attention to privacy regulations. However, the absence of published security policies and incident response contacts is a gap in transparency and preparedness. No security headers were detected in the HTML content, suggesting room for improvement in HTTP header security controls. The use of Matomo analytics over more invasive trackers is a positive privacy and security indicator. Overall, the site is secure but could benefit from enhanced security documentation and technical header implementations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information to facilitate vulnerability reporting and security communication.
  3. Implement and enforce security HTTP headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance transparency by including data retention policies and detailed privacy compliance statements.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust open-source content management system widely used in enterprise and non-profit sectors. It uses SVG for scalable graphics and asynchronous JavaScript modules to improve performance and user experience. Matomo analytics is integrated for privacy-respecting user tracking. The site is responsive and optimized for mobile devices, with good accessibility and SEO practices evident from meta tags and structured navigation. Performance is moderate, likely due to rich media content and complex navigation structures. Hosting provider details are not explicitly disclosed. Overall, the technical infrastructure is modern and well-maintained, supporting the organization's digital presence effectively.
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.
