Wienerberger.cz is the Czech Republic website for Wienerberger, a leading manufacturer of building materials including bricks, roof tiles, facing bricks, and paving products. The site targets construction professionals and homeowners seeking quality building solutions. The company is positioned as a major player in the manufacturing sector with a broad product portfolio. Technically, the website is built on Adobe Experience Manager, leveraging modern marketing and analytics tools such as Google Tag Manager, Cookiebot for consent management, and Hotjar for user behavior analysis. The site is well-optimized for SEO and mobile devices, with good design and user experience. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though explicit security headers could be further verified.

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 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';…
  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

Wienerberger operates in the manufacturing sector, focusing on building materials. Their business model revolves around production and distribution of bricks, roof tiles, and paving products. The website content and metadata indicate a strong market position in the Czech Republic, targeting builders and homeowners. The company uses advanced digital marketing and analytics tools to optimize user engagement and advertising effectiveness. The lack of visible contact information on the homepage suggests that detailed contact data may be located deeper in the site or handled via other channels. The company maintains GDPR compliance and transparent privacy policies, supporting trust with European customers. No suspicious or affiliate domains were identified, indicating a focused and direct business approach.

Security posture

The website enforces HTTPS and uses cookie consent management compliant with GDPR, indicating a mature privacy and security approach. Security headers are likely present given the use of Adobe Experience Manager and Adobe Launch, but explicit header details were not extracted. No exposed sensitive data or vulnerable scripts were detected in the HTML content. The use of multiple third-party analytics and marketing scripts introduces some risk, but these are industry-standard tools. The absence of WHOIS data is a concern for domain legitimacy verification but does not directly impact website security. Overall, the security posture is good with room for improvement in explicit header transparency and continuous monitoring of third-party scripts.

Recommendations

  1. Verify and publish explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Enhance accessibility features to meet higher standards for users with disabilities.
  3. Provide clear and easily accessible contact information on the homepage or main navigation.
  4. Conduct regular audits of third-party scripts to mitigate supply chain risks.
  5. Investigate and resolve the missing WHOIS data to improve domain trustworthiness.

Technical notes

Notes

The website is built on Adobe Experience Manager, a robust enterprise CMS platform, indicating a high level of technical maturity. It integrates Google Tag Manager, Cookiebot, and Hotjar for analytics, consent management, and user behavior tracking. The site uses modern web fonts and responsive design techniques for good mobile optimization. Performance is moderate, likely influenced by multiple external scripts. SEO is well addressed with proper meta tags, Open Graph data, and structured JSON-LD markup. No critical technical debt or outdated technologies were detected. Hosting provider details were not explicitly found. Overall, the technical infrastructure supports a professional and scalable web presence.
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.
