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

Golfový klub Osyčina is a regional golf club located in Dobříkov u Chocně, Czech Republic, operating a 9-hole golf course with additional facilities such as a driving range, practice areas, and a golf simulator. The club offers services including training, tournaments, children's activities, and accommodation in a traditional wooden clubhouse and partner pension. The website reflects a small but active community-focused business with a clear target audience of golf enthusiasts and families in the region. Technically, the website uses a custom CMS (Web-SOUL) with legacy technologies such as jQuery 1.11.3 and FancyBox for galleries. It integrates Google Analytics, Google Tag Manager, and Facebook SDK for tracking and marketing. The site has basic mobile optimization and accessibility features but could benefit from modernization and performance improvements. From a security perspective, the site uses HTTPS and implements cookie consent mechanisms, indicating GDPR awareness. However, no explicit security headers were detected, and the use of an outdated jQuery version poses potential vulnerabilities. WHOIS data is unavailable, which reduces domain trustworthiness, but the active social media presence and detailed content support legitimacy. Overall, the website is functional and professional for its business scope but should address technical and security improvements to enhance trust and 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

Golfový klub Osyčina operates in the hospitality and sports sector, focusing on golf-related services including course operation, training, events, and accommodation. The club targets local and regional golf players, families, and corporate clients. Its business model relies on green fees, membership fees, training packages, event hosting, and accommodation partnerships. The club maintains a strong community presence with a history of tournaments dating back over a decade. Partnerships with local accommodation providers and tourism portals enhance its market reach. The website content and social media integration indicate a stable but small-scale operation with opportunities for growth through digital modernization and expanded marketing.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and cookie consent implemented, reflecting compliance with privacy regulations. However, the absence of security headers such as Content Security Policy, X-Frame-Options, and HSTS reduces protection against common web attacks. The use of an outdated jQuery library version is a notable vulnerability that could expose the site to known exploits. No public incident response or vulnerability disclosure policies are present, limiting transparency. The lack of WHOIS data further impacts trust. To improve security maturity, the club should update dependencies, implement security headers, and publish clear security policies.

Recommendations

  1. Update jQuery and other JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish explicit security and incident response policies on the website to enhance transparency and preparedness.
  4. Verify and correct domain WHOIS registration to improve domain trust and legitimacy.
  5. Enhance mobile optimization and accessibility to improve user experience and SEO.

Technical notes

Notes

The website is built on a custom CMS (Web-SOUL) and uses legacy JavaScript libraries such as jQuery 1.11.3 and FancyBox 3.3.4 for UI components. It integrates Google Analytics and Facebook SDK for analytics and marketing. The site loads multiple external scripts and stylesheets, some asynchronously, which helps performance but also increases third-party dependencies. The HTML structure is traditional with clear navigation and event calendar features. Mobile responsiveness is basic but functional. There is room for modernization by adopting newer frameworks, improving SEO metadata, and optimizing performance metrics.
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.
