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

Heidelberg Materials CZ operates as a major provider of transport concrete and related construction materials across the Czech Republic. The company offers comprehensive services including production, delivery, and pumping of concrete, as well as manufacturing of various mortars and screeds. It is part of the larger Heidelberg Materials group, which is a recognized leader in the building materials industry. The website reflects a professional corporate presence with clear branding and a focus on serving construction professionals such as builders, developers, and architects. Technically, the site uses modern JavaScript libraries, Google Tag Manager for analytics, and a proprietary CMS, delivering a moderately fast and mobile-optimized experience. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though additional security headers could enhance protection. The absence of WHOIS data is a notable gap but does not detract significantly from the overall legitimacy given the strong corporate branding and content quality. Overall, the site is well-positioned to support the company's business objectives and maintain trust with its audience.

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.

Priority findings

9 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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 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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 in the Czech construction materials sector, leveraging its affiliation with Heidelberg Materials to provide a wide range of concrete products and services. Its business model centers on manufacturing and distributing concrete and related materials, complemented by logistics and technical consulting services. The target customers include individual home builders, construction firms, developers, and architects, indicating a broad market reach. The presence of multiple subsidiaries and partner domains suggests a well-established ecosystem supporting diverse construction needs. The website content and structure indicate a mature digital presence aimed at facilitating customer engagement and service delivery. Strategic partnerships and comprehensive service offerings position the company competitively within the industry.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and a cookie consent banner compliant with GDPR. However, the lack of explicit security incident response contacts and vulnerability disclosure policies indicates room for improvement in transparency and readiness. The use of third-party scripts like Google Tag Manager and 2b-advice cookie manager is standard but requires ongoing monitoring to mitigate supply chain risks. Security headers beyond basic cache control and HSTS are not evident, suggesting potential enhancements to prevent clickjacking, MIME sniffing, and cross-site scripting attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is adequate for a corporate informational site but could be strengthened with additional controls and disclosures.

Recommendations

  1. Implement additional HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish clear incident response and vulnerability disclosure information to improve transparency and facilitate security communication.
  3. Regularly audit and update third-party scripts to minimize risks from supply chain vulnerabilities.
  4. Consider adding explicit company contact emails and phone numbers on the website to improve business credibility and user trust.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website is built on a proprietary CMS (NGS CMS) and uses modern front-end technologies including Swiper.js for carousels and Google Web Fonts for typography. Google Tag Manager is employed for analytics and marketing tracking. The site is mobile responsive with a clear navigation structure and optimized meta tags for SEO. Performance is moderate, with some room for improvement in loading speed and accessibility compliance. The technical implementation is solid but could benefit from enhanced security headers and more explicit accessibility features. The absence of WHOIS data is a technical anomaly but does not impact the site's operational infrastructure.
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.
