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

7 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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 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
      • 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 and real estate development sectors, with diversified services and a subsidiary focused on engineering design. Their business model integrates construction, manufacturing, and energy sectors, targeting commercial, industrial, and residential clients. The website reflects a medium to large enterprise with a professional brand image and trust signals such as certifications and GDPR compliance. Partnerships with companies like Kangaroo group for web development indicate a collaborative ecosystem. Growth indicators include ongoing development projects and a comprehensive service portfolio.

Security posture

The website employs HTTPS and integrates reCAPTCHA on its contact form, demonstrating awareness of basic security practices. The cookie consent mechanism is robust, allowing granular user control, aligning with GDPR requirements. However, the lack of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options suggests potential areas for enhancement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a security policy or incident response contact limits transparency in security governance. Overall, the security posture is moderate but could benefit from additional hardening and policy disclosures.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish explicit security and incident response policies to improve transparency and user trust.
  3. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.

Technical notes

Notes

The website is built on a modern front-end stack utilizing jQuery 3.7.0, Swiper.js for sliders, Font Awesome for icons, and Google Fonts for typography. The site loads external resources from reputable CDNs, contributing to performance and reliability. The presence of a cookie consent banner with detailed settings indicates compliance with privacy regulations. The site is mobile-optimized with responsive design elements. However, no CMS or backend platform was identified from the HTML content. Performance is moderate, with potential improvements in SEO and accessibility. The absence of security headers and WHOIS data are technical risks that should be addressed to improve overall site trustworthiness and security.
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.
