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

SK Sigma Olomouc is a well-established Czech football club with a strong local and national presence. The website serves as the official digital platform for the club, providing news, match information, ticket sales, merchandise, and multimedia content to fans and stakeholders. The club operates a fanshop and maintains active engagement through multiple social media channels, reflecting a mature digital presence. The domain age and WHOIS data confirm the legitimacy and long-standing nature of the organization. Technically, the website uses modern JavaScript libraries such as jQuery and Swiper.js, integrates Google Analytics and Google Tag Manager for tracking, and supports multilingual access via Google Translate. The site is hosted by GRANSY, a known Czech hosting provider, and employs HTTPS with a good SSL configuration. The design is responsive and user-friendly, with clear navigation and professional branding. From a security perspective, the site enforces HTTPS and implements a cookie consent mechanism aligned with GDPR requirements. However, it lacks visible security headers and does not publish a clear privacy policy or terms of service, which are important for compliance and user trust. No direct contact information or incident response contacts are provided, limiting transparency in security matters. Overall, the website is professional and trustworthy but would benefit from enhanced privacy disclosures, security headers, and explicit contact details to improve compliance and security posture. The risk level is moderate with no critical vulnerabilities detected in the provided content.

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. 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
  • 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 holds a solid market position as a medium-sized sports organization in the Czech Republic, targeting football fans and local communities. Revenue streams likely include ticket sales, merchandise, sponsorships, and media rights. The partnership ecosystem includes well-known brands such as Adidas, Tipsport, and Chance, indicating strong commercial relationships. The website content and structure support fan engagement and brand loyalty, with active news updates and multimedia content. Growth indicators include participation in international competitions and a comprehensive youth academy. Strategic observations suggest opportunities to enhance digital compliance and security to maintain competitive advantage.

Security posture

The current security maturity is moderate. HTTPS is enforced, and cookie consent is implemented, demonstrating awareness of privacy regulations. However, the absence of security headers like Content-Security-Policy and lack of published privacy and security policies represent compliance gaps. No vulnerability disclosure or incident response information is available, which could hinder timely handling of security incidents. The use of third-party scripts necessitates regular audits to prevent supply chain risks. Overall, the security culture appears basic but can be improved with formalized policies and technical controls.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the website footer.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  3. Provide clear contact information for security incidents, including dedicated security or abuse email addresses.
  4. Regularly review and update third-party scripts and tracking tools to mitigate vulnerabilities.
  5. Develop and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website infrastructure is built on a modern tech stack including jQuery, Swiper.js, and Bootstrap, ensuring responsive design and interactive features. Hosting is provided by GRANSY, a reputable Czech hosting provider. Performance is moderate with room for optimization. SEO is supported by proper meta tags and Open Graph data. Accessibility features are basic but present. The use of Google Translate enhances multilingual support. Technical risks include reliance on multiple third-party scripts and absence of advanced security headers. Opportunities exist to improve performance and security through optimization and enhanced headers.
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.
