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

CLUBSPIRE.cz is a Czech-based software solution specializing in comprehensive management systems for fitness and sports centers. The platform offers a wide range of modules including reservation systems, membership management, email marketing, access control, and point of sale functionalities. With a client base of over 200 sports centers, CLUBSPIRE positions itself as a reliable and efficient tool for business managers in the fitness industry. The website reflects a professional and consistent brand image, supported by active content updates and social media engagement. Technically, the website employs a modern technology stack including Java-based backend architecture, Google reCAPTCHA for form security, and Google Analytics for user tracking. The site is optimized for multiple platforms including Windows, Linux, and Apple, and demonstrates good mobile responsiveness and SEO practices. Security measures such as HTTPS and consent-based cookie management are implemented, though some security headers could be enhanced. From a security perspective, the site shows a solid posture with encrypted communications and protection against automated abuse via CAPTCHA. However, the absence of published security policies and incident response contacts suggests room for improvement in transparency and preparedness. The lack of WHOIS data limits the ability to fully verify domain legitimacy, though the professional presentation and active business operations mitigate some concerns. Overall, CLUBSPIRE.cz is a credible and well-maintained business website with good technical and security foundations. Strategic enhancements in security policy publication, WHOIS transparency, and accessibility would further strengthen its trustworthiness and compliance posture.

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

3 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 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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

CLUBSPIRE operates in the niche market of fitness and sports center management software, leveraging a SaaS business model. Its competitive advantage lies in its comprehensive module offering and long-term client relationships. The company targets fitness center managers and owners seeking to streamline operations and improve customer engagement. Revenue streams likely include software subscriptions, hardware sales, and support services. The active blog and social media presence indicate a focus on customer education and community building. Partnerships with technology providers and a dedicated development team support continuous product evolution. The company appears medium-sized with a stable market position in the Czech Republic and potentially neighboring regions.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA to prevent automated abuse, and cookie consent mechanisms aligned with GDPR. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap. Additionally, no public security policy or incident response contact information is provided, which could hinder transparency and user trust. The WHOIS data is unavailable, which reduces domain trust assessment confidence. Overall, the security posture is good but could benefit from enhanced header policies and published security documentation.

Recommendations

  1. Publish a comprehensive security policy and incident response contact information on the website.
  2. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Investigate and resolve the lack of WHOIS data to improve domain transparency and trust.
  4. Enhance website accessibility features to meet higher standards and improve user experience.
  5. Regularly audit third-party scripts and tracking tools to ensure no vulnerabilities or privacy issues.

Technical notes

Notes

The website is built on a Java-based backend with a modern 3-layer architecture ensuring secure and efficient data handling. Frontend technologies include HTML5, CSS3, SVG graphics, and JavaScript with asynchronous loading of scripts for performance optimization. Integration with Google services such as reCAPTCHA, Analytics, and Tag Manager is evident. The site supports multiple platforms (Windows, Linux, Apple) and offers mobile applications. Performance is moderate with good SEO and mobile optimization. The CMS or framework appears custom-built, which may require dedicated maintenance resources. Opportunities exist to improve security headers and accessibility compliance to reduce technical risks.
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.
