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

Jihlavský plavecký klub, z.s. is a small, community-focused swimming club based in Jihlava, Czech Republic. The organization provides swimming training, organizes competitions, and engages with local members and supporters. The website serves as an information hub for news, events, membership, and contact details, targeting local swimmers and their families. The club maintains an active presence on Facebook and provides clear contact channels including email, phone, and a contact form. The domain is newly registered in late 2023, consistent with the club's recent establishment or digital presence launch. Technically, the website is built on WordPress using popular plugins such as Elementor for design, Yoast SEO for optimization, and Complianz for GDPR compliance. The site is hosted likely by Wedos, a Czech hosting provider, and uses HTTPS with a valid SSL certificate. Performance and mobile optimization are good, with basic accessibility features. SEO is well implemented with meta tags and structured data. From a security perspective, the site uses HTTPS and cookie consent mechanisms, but lacks explicit security headers and dedicated security or incident response policies. No vulnerabilities or exposed sensitive data were detected in the HTML content. The WHOIS data is consistent and legitimate, with no privacy protection or suspicious patterns. Overall, the security posture is solid but could be improved by adding security headers and formal policies. The website content is safe for general audiences, with no adult or questionable content. Privacy compliance is good with accessible privacy and cookie policies. Business credibility is supported by clear contact information and trust signals such as social media presence and structured data. The overall risk is low, but strategic improvements in security policies and headers are recommended to enhance trust and protection.

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. 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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

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 club operates in the non-profit sports sector, focusing on swimming activities in the Jihlava region. Its business model revolves around community engagement, training services, and event organization. The club leverages partnerships with local sponsors and sports organizations, as evidenced by linked domains and sponsor logos. The target customers are children and local swimmers. The website supports growth by providing easy access to membership applications and news updates. The club's market position is local and community-oriented, with potential for expansion through digital engagement. The partnership ecosystem includes regional sports bodies and local businesses, enhancing credibility and resource access.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and cookie consent is implemented in compliance with GDPR. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap. No incident response or security policy pages are present, limiting transparency on security governance. The site does not expose sensitive data or use vulnerable libraries in the visible content. Forms are standard and protected by WordPress mechanisms but could benefit from additional security measures such as CAPTCHA or input validation disclosures. Overall, the security culture appears basic but functional, with room for enhancement in formal policies and technical controls.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Regularly update WordPress core and plugins to minimize vulnerability risks.
  4. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance form security with CAPTCHA or similar anti-bot measures and communicate data protection practices to users.

Technical notes

Notes

The website is built on a modern WordPress infrastructure using Elementor for page building and Yoast SEO for optimization. It integrates several plugins for photo galleries, download management, and GDPR compliance. The hosting is likely provided by Wedos, a Czech hosting provider, consistent with the domain registrar. The site uses Google Fonts and jQuery libraries, with asynchronous loading for performance. Mobile optimization is good, and SEO metadata is comprehensive including Open Graph and JSON-LD structured data. Performance is moderate with no major issues detected. Technical debt appears low, but the site could benefit from enhanced security headers and accessibility improvements to meet higher standards.
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.
