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

4 findings rated critical or high. Fix these first.

  1. 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';…

  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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 website positions AC Sparta Praha as a leading football club in the Czech Republic, focusing on fan engagement and ticket sales. The business model revolves around sports entertainment and community building. The site integrates multiple third-party services for analytics and advertising, indicating a data-driven approach to marketing and audience targeting. While no direct contact information or terms of service were found, the presence of a comprehensive privacy and cookie policy reflects attention to regulatory compliance. The club benefits from a strong brand and long-standing market presence, with opportunities to enhance transparency by publishing security policies and contact channels for incident reporting.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, use of security headers, and a robust cookie consent mechanism. The integration of reputable third-party analytics and advertising services is managed with user consent, aligning with GDPR requirements. However, the absence of a published security policy or incident response contact limits transparency in security governance. No vulnerabilities or exposed sensitive data were detected in the analyzed content. To improve, the organization should consider publishing a security policy, incident response procedures, and a vulnerability disclosure program to enhance trust and readiness.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Add clear incident response contact information such as security@ or abuse@ email addresses.
  3. Develop and publish a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Enhance website accessibility features to meet compliance standards.
  5. Maintain regular audits of third-party scripts and update them to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using Next.js, a modern React framework, indicating a contemporary and scalable technical infrastructure. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site uses Cookiebot for cookie consent management, Google Tag Manager for analytics deployment, and Microsoft Clarity for user behavior insights. Performance is moderate with good mobile optimization and SEO practices. Accessibility is basic and could be improved. The technical stack is well-chosen for a sports club website, balancing user experience, compliance, and marketing needs. Opportunities exist to enhance accessibility and publish more detailed technical and security documentation.
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.
