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

HELUZ cihlářský průmysl a. s. operates the HELUZ NA MAX program, providing unique partner benefits and construction materials primarily targeting builders and homeowners in the Czech Republic. The company is positioned as a large manufacturing entity within the construction sector, supported by its parent company HELUZ Group. The website offers detailed information about the program benefits, partner offers, and links to related corporate resources. Technically, the website employs modern JavaScript libraries and tracking tools, ensuring a moderate to good user experience with mobile optimization and SEO considerations. Security posture is solid with HTTPS and no visible vulnerabilities, though security headers and explicit security policies could be improved. Privacy and cookie policies are present but lack active consent mechanisms. The absence of WHOIS data limits domain trust assessment, but the website's professional presentation and official links support legitimacy. Overall, the site is a credible digital asset for HELUZ's partner program with room for enhanced security and privacy compliance.

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

11 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

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 · found on this site
  • 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

HELUZ maintains a strong market position in the Czech construction materials manufacturing sector, leveraging a partner benefit program to enhance customer loyalty and market reach. The business model focuses on supplying building materials and value-added services through partnerships. The website reflects a mature digital presence with integrated marketing and tracking tools, supporting targeted campaigns and user engagement. The company’s ecosystem includes multiple related domains and portals, indicating a broad operational footprint. Growth indicators include active social media channels and detailed program offerings. Strategic partnerships and clear branding reinforce market credibility. However, the lack of direct contact information on the main site may limit immediate customer engagement.

Security posture

The website demonstrates a good security baseline with enforced HTTPS and absence of exposed sensitive data. Use of reputable third-party analytics and marketing scripts is evident, though these introduce moderate user tracking. The lack of security headers such as Content-Security-Policy and absence of a security.txt file or explicit incident response contacts indicate areas for improvement. No visible vulnerabilities or outdated libraries were detected. Compliance with GDPR is suggested by the presence of privacy and cookie policies, but the missing cookie consent mechanism and absence of detailed data retention policies highlight compliance gaps. Incident response readiness and security culture indicators are not publicly documented, suggesting a need for enhanced transparency and formalization of security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  2. Deploy an explicit cookie consent mechanism to comply fully with GDPR and enhance user privacy transparency.
  3. Publish a security policy and incident response information to improve trust and readiness for security events.
  4. Introduce a security.txt file to facilitate vulnerability disclosure and responsible reporting.
  5. Regularly audit and update third-party scripts to minimize risks from external dependencies and tracking.

Technical notes

Notes

The website uses a modern tech stack including jQuery, Typekit fonts, Google Tag Manager, Facebook Pixel, and Smartlook for analytics and marketing. The HTML structure is valid with proper meta tags supporting SEO and social sharing. Performance is moderate with asynchronous loading of scripts. Mobile optimization is good, ensuring accessibility across devices. However, accessibility features are basic and could be enhanced for compliance with standards. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The site’s technical implementation supports business goals but could benefit from modernization in security and accessibility.
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.
