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

BK Olomoucko is a Czech basketball club competing in the top-tier Kooperativa NBL league. The website provides comprehensive information about the team roster, match schedules, league standings, and news updates, targeting basketball fans and the local community. The club maintains partnerships with local organizations and sponsors, enhancing its market presence. Technically, the website employs modern web technologies including Bootstrap, SVG icons, and Google Analytics, hosted by REG-GRANSY. The site is mobile optimized and offers a good user experience with clear navigation and professional design.

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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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

BK Olomoucko operates as a medium-sized sports club focused on basketball in the Czech Republic. Its business model revolves around sports competition, fan engagement, merchandising via a fanshop, and sponsorships from a broad partner ecosystem. The club leverages partnerships with local businesses and media to strengthen its brand and community ties. The website reflects active content management with recent news and match updates, indicating ongoing engagement and growth. The presence of youth and partner clubs suggests a strategic approach to talent development and regional influence. The club's digital presence is professional but could benefit from enhanced compliance and security transparency to build further trust.

Security posture

The website demonstrates a moderate security maturity level. It uses HTTPS, which is mandatory for secure communications, and does not expose sensitive data in the HTML content. However, it lacks visible security headers such as Content Security Policy, HSTS, or X-Frame-Options, which are important for mitigating common web attacks. There is no evidence of a vulnerability disclosure policy or security.txt file, which limits transparency and incident response readiness. Privacy compliance is weak due to the absence of privacy and cookie policies and no consent mechanism for tracking cookies like Google Analytics. The site does not appear to have forms collecting sensitive data, reducing immediate risk, but overall security posture would benefit from improvements in policy disclosures and technical controls.

Recommendations

  1. Implement and prominently link a comprehensive privacy policy and cookie policy to comply with GDPR and enhance user trust.
  2. Add a cookie consent mechanism to obtain user consent for tracking and comply with privacy regulations.
  3. Deploy security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options to strengthen defense against common web vulnerabilities.
  4. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting and incident management.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used and maintain secure coding practices.

Technical notes

Notes

The website is built with modern front-end technologies including HTML5, CSS3, JavaScript, and Bootstrap framework, ensuring responsive design and good user experience across devices. It uses SVG for icons and Google Fonts for typography, enhancing visual appeal. Google Analytics is integrated for visitor tracking, but without a consent mechanism. Hosting is provided by REG-GRANSY, a known registrar and hosting provider, with multiple name servers indicating stable infrastructure. Performance is moderate, with optimized images and lazy loading used. The site lacks explicit CMS identification, suggesting a custom or proprietary solution. Accessibility features are basic, and SEO is supported by proper meta tags and Open Graph data. Overall, the technical implementation is solid but could be improved with enhanced accessibility and privacy compliance features.
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.
