Risk levelMedium

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

Klinker Centrum s.r.o. is a well-established Czech company specializing in the supply and realization of clay brick facades, including facing bricks, brick cladding, paving bricks, and fired roofing tiles. With over 25 years of experience, the company positions itself as a market leader in the Czech Republic, offering comprehensive services from product supply to facade realization. The website reflects a mature digital presence with professional design, clear navigation, and active content updates including news and a magazine section. Technically, the site employs modern analytics and marketing tools such as Google Analytics, Facebook Pixel, Hotjar, and Google Tag Manager, alongside security measures like Google reCAPTCHA and cookie consent mechanisms. However, the absence of WHOIS data and lack of visible HTTP security headers suggest areas for improvement in domain transparency and security hardening. Overall, the site is safe, GDPR compliant, and provides multiple contact channels, supporting both B2B and B2C customer engagement.

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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';…

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 targets construction professionals, architects, and end customers interested in high-quality brick facades and roofing materials. Its business model combines product sales with service offerings such as facade realization and expert consultancy. The presence of two physical locations and a large inventory indicates a medium-sized operation with significant market reach. The website's active content strategy and social media presence support brand awareness and customer engagement. Partnership with eBRÁNA s.r.o. for website development suggests professional digital collaboration. The lack of WHOIS transparency is a minor concern but does not detract significantly from the company's apparent legitimacy and market position.

Security posture

The website demonstrates a moderate security posture with the implementation of Google reCAPTCHA on forms and a comprehensive cookie consent banner supporting GDPR compliance. The use of multiple third-party analytics and marketing scripts introduces potential risk vectors that require ongoing monitoring. The absence of detected HTTP security headers such as Content Security Policy, HSTS, or X-Frame-Options is a notable gap that could be addressed to enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were identified in the HTML content. Incident response and security policy information are not publicly available, indicating an opportunity to improve transparency and readiness.

Recommendations

  1. Implement and enforce HTTP security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Conduct regular security audits of third-party scripts and dependencies to mitigate risks from external libraries.
  3. Enhance domain transparency by ensuring WHOIS data is complete and publicly accessible to improve trustworthiness.
  4. Publish a clear security policy and incident response plan on the website to demonstrate security maturity.
  5. Maintain and update privacy and cookie policies regularly to stay compliant with evolving regulations and best practices.

  5. Use of modern tracking and analytics tools with consent mechanisms.

Technical notes

Notes

The website is built on a custom CMS platform with integration of modern web technologies and third-party services for analytics, marketing, and user experience enhancements. Performance is moderate with good mobile optimization and accessibility features. SEO practices are well implemented with appropriate meta tags and structured navigation. The site uses lazy loading for images to improve load times. However, the lack of visible security headers and incomplete WHOIS data represent technical risks. Hosting provider details are not disclosed, which limits full infrastructure assessment. Overall, the technical implementation supports a professional and user-friendly online presence but could benefit from enhanced security configurations and transparency.
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.
