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

The website klasikduatlon.cz is dedicated to organizing and promoting duathlon events in Příbram, Czech Republic, targeting athletes and sports enthusiasts. It provides detailed information about race categories, schedules, registration, and event logistics. The site is built on WordPress using common libraries such as jQuery and Bootstrap, with moderate mobile optimization and basic SEO features. However, it lacks critical security features such as HTTPS and security headers, and does not provide privacy or cookie policies, which are essential for compliance and user trust. The domain registration data is inconsistent with the website's content timeline, raising questions about the domain's history and ownership transparency. Overall, the site serves its business purpose but requires significant improvements in security and compliance to enhance trustworthiness and protect users.

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

  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

      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

Klasik duatlon operates as a small-scale event organizer focusing on duathlon races in the Czech Republic. Its business model revolves around hosting competitive sports events with multiple race categories, including adult and children's races. The website demonstrates a local market position with a niche audience of athletes and sports clubs. Sponsorships, such as from ferovakasina.com, indicate some partnership ecosystem. The absence of detailed business registration data and contact emails limits transparency. The site content and testimonials suggest a positive reputation within its community. Growth potential may depend on improving digital presence and compliance.

Security posture

The website currently exhibits a low security posture. The absence of HTTPS is a critical vulnerability that exposes users to data interception risks. No security headers are present to mitigate common web attacks. There is no visible incident response contact or security policy, which limits preparedness for security events. The site does not implement privacy or cookie policies, risking non-compliance with GDPR and related regulations. No vulnerable libraries were detected, but the outdated domain registration and minimal WHOIS data reduce trust. Immediate remediation of HTTPS and security policies is recommended.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure user connections.
  2. Add comprehensive privacy and cookie policies with user consent mechanisms to comply with GDPR.
  3. Publish clear contact information for security incidents and establish an incident response process.
  4. Enhance website security by adding HTTP security headers such as Content-Security-Policy and X-Frame-Options.
  5. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities and improve performance.

Technical notes

Notes

The website uses WordPress CMS with jQuery and Bootstrap frameworks, indicating a standard and widely supported technology stack. The site includes Easy Fancybox for image display. The HTML structure is valid and includes meta tags for viewport and description, but lacks Open Graph or Twitter Card metadata for social sharing. Performance appears moderate with no explicit optimization scripts detected. Mobile responsiveness is basic but functional. Accessibility features are minimal. The domain uses name servers that do not clearly align with the website brand, and no hosting provider information is available. No analytics or tracking scripts were found, indicating minimal user tracking.
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.
