TJ Volejbal Ostrava is a regional volleyball sports club based in Ostrava, Czech Republic, offering professional training, team collaboration, and community engagement primarily focused on youth and adult volleyball teams. The club actively participates in national leagues and organizes events and tournaments, supported by a network of sponsors and partners. The website reflects a well-maintained digital presence with regular updates on matches, news, and social media integration. Technically, the site uses a custom CMS (Contimex) with modern web technologies and is mobile-optimized, though some improvements in accessibility and security headers are recommended.

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

    • 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. 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 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 club operates as a small-sized sports entity focused on volleyball, targeting athletes, families, and sports enthusiasts in the Ostrava region. Its business model relies on sponsorships, partnerships, and community events rather than commercial sales. The presence of multiple partners and sponsors indicates a stable ecosystem supporting the club's activities. The website's content and structure support engagement with current and prospective members, providing schedules, news, and multimedia content. Growth potential lies in expanding youth programs and enhancing digital engagement. The club maintains a positive market position within regional sports but does not appear to have broader commercial ambitions.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communication. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options exposes the site to potential risks like clickjacking and MIME sniffing. No forms with sensitive data were detected in the provided content, reducing immediate risk exposure. The absence of a cookie consent mechanism may pose GDPR compliance issues. No known vulnerabilities or malware indicators were found. Incident response and security policies are not publicly documented, which could hinder rapid response to security incidents. Overall, the security maturity is moderate but can be improved with standard best practices.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Add a cookie consent banner and mechanism to comply with GDPR and improve user privacy transparency.
  3. Publish security and incident response policies to demonstrate commitment to security and facilitate incident handling.
  4. Conduct a security audit to identify and remediate any hidden vulnerabilities or outdated libraries.
  5. Improve accessibility features to ensure compliance with standards and enhance user experience for all visitors.

Technical notes

Notes

The website is built on a custom CMS platform (Contimex) using modern HTML5, CSS3, and JavaScript technologies including jQuery and lazysizes for lazy loading images. The site is mobile responsive with good navigation clarity and SEO optimization. Performance is moderate, with multiple CSS files loaded asynchronously and image optimization via responsive images. No major technical debt or deprecated technologies were detected. Hosting provider details are not disclosed. The site lacks some accessibility features and security headers, which are areas for technical improvement. Overall, the technical infrastructure supports the business needs effectively with room for modernization in security and privacy compliance.
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.
