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

Golf Club Lázně Kostelec is a small hospitality and recreation business located in the Czech Republic, offering a comprehensive golf facility including a nine-hole course, driving range, indoor golf, and associated hotel and spa services. The website presents a professional and well-structured digital presence with clear navigation and relevant content targeting golf enthusiasts and visitors seeking leisure and wellness experiences. Technically, the site employs standard web technologies such as jQuery, Google Analytics, and Google Maps API, with HTTPS enabled ensuring secure communications. However, some technical improvements are recommended, including updating libraries and enhancing security headers. The security posture is generally good with no critical vulnerabilities detected, but the absence of cookie consent and security policy pages indicates room for compliance improvements. The lack of WHOIS data reduces domain trustworthiness, but the website content and contact details support legitimacy. Overall, the site is safe, user-friendly, and suitable for its target audience.

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

10 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 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

  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 business operates in the hospitality and recreation sector, focusing on golf and spa services. It targets local and regional customers interested in golf, training, and wellness. The business model combines golf course operations, accommodation, dining, and event hosting. The website indicates active engagement with customers through newsletters and event calendars. The partnership with tycko.cz for reservations suggests integration with third-party service providers. The company maintains a consistent brand image and provides comprehensive service information, positioning itself as a reputable local golf club and leisure destination.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and secure form handling including anti-spam honeypot fields. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options is a gap. The use of an outdated jQuery version could expose the site to known vulnerabilities. No incident response or security policy information is published, which limits transparency and preparedness. GDPR compliance is addressed via a privacy policy, but cookie consent mechanisms are missing. Overall, the security posture is adequate for the business size but could be improved to reduce risk and enhance trust.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web attacks.
  2. Add a cookie consent banner to comply with EU cookie laws and improve privacy compliance.
  3. Upgrade jQuery and other JavaScript libraries to the latest stable versions to address known vulnerabilities.
  4. Publish a security policy and incident response contact information to enhance transparency and preparedness.
  5. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website uses a traditional tech stack with jQuery 1.8.3, Google Analytics, Google Tag Manager, and Google Maps API. The HTML is valid and the site is mobile responsive with good navigation clarity. Performance is moderate, likely due to multiple external scripts and map integrations. No CMS is explicitly detected. Hosting provider details are not available. Accessibility features are basic but present. SEO optimization is basic with meta tags but no structured data or Open Graph tags detected. The site could benefit from modernization and performance optimization to improve user experience and technical robustness.
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.
