HZ Hotel s.r.o. · Hospitality · Czech Republic

High risk. 9 critical or high findings in Security headers, GDPR outside view and 2 other checks.

Security score

47/100

Risk levelHigh

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

Chateau de Frontiere is a luxury 4-star hotel resort located in South Moravia, Czech Republic, within the UNESCO-listed Lednicko-valtický area. The business offers upscale accommodation, wellness, fine dining through its restaurants ESSENS and Chateau Petit, wine cellar experiences, and event hosting services. The website is professionally designed with multilingual support and integrated booking functionality, reflecting a mature digital presence. Technically, the site uses modern libraries and tracking tools but lacks some advanced security headers and explicit incident response information. The security posture is adequate with HTTPS and cookie consent mechanisms but could be improved with additional security best practices. WHOIS data is missing, which slightly reduces trustworthiness, but the overall business credibility is high due to clear contact information, social media presence, and external references.

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

9 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • 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

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 operates in the hospitality sector targeting luxury travelers and event organizers. It leverages its unique location and cultural heritage to position itself as a premium resort. Revenue streams include accommodation, wellness services, fine dining, and event hosting. The business maintains partnerships with local wineries and attractions, enhancing its ecosystem. The website content and external links indicate a well-established operation with a focus on quality and customer experience. Growth potential exists through enhanced digital marketing and expanded service offerings.

Security posture

The website enforces HTTPS and implements cookie consent aligned with GDPR. However, it lacks visible security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web attacks. No dedicated security or incident response policies are published, and no vulnerability disclosure program is evident. The use of third-party booking widgets and tracking pixels introduces potential privacy considerations. Overall, the security maturity is moderate but can be improved to enhance trust and compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  2. Publish an incident response policy and provide dedicated security contact channels.
  3. Establish a vulnerability disclosure program and publish a security.txt file.
  4. Regularly update third-party libraries and monitor for vulnerabilities.
  5. Enhance accessibility features and conduct periodic security audits.

Technical notes

Notes

The website uses a combination of Bootstrap, jQuery, Swiper.js, and third-party booking widgets from D-Edge, indicating a modern but somewhat traditional tech stack. Performance is moderate with responsive design and mobile optimization. SEO is supported by proper meta tags and structured content. However, the site could benefit from improved accessibility and performance optimizations. Hosting provider details are not disclosed. The integration of multiple tracking and marketing tools suggests a focus on analytics and user engagement but requires careful privacy management.
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.
