High risk. 8 critical or high findings in Security headers, GDPR outside view and 3 other checks.

Security score

48/100

Risk levelHigh

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

The website 'ČUS Sportuj s námi!' serves as a platform promoting sports events across the Czech Republic. It targets sports enthusiasts and participants by providing event listings, filtering options by region, sport, and date, and general project information. The site leverages WordPress CMS and integrates common technologies such as jQuery, Google Maps API, and social media plugins to enhance user engagement and navigation. While the site is accessible and well-structured with good content quality and mobile optimization, it lacks explicit privacy and terms of service policies, which are critical for compliance and user trust. Security posture is moderate with HTTPS enabled but missing security headers and limited visible security policies. The absence of WHOIS data reduces domain trustworthiness, though the site appears legitimate based on content and external integrations.

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

8 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

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 platform operates in a niche market segment focused on sports event promotion within the Czech Republic. It likely generates value through information dissemination and community engagement rather than direct sales. The presence of social media channels and Google Maps integration suggests an emphasis on user interaction and event accessibility. The business model appears to be informational and promotional, targeting a general audience interested in sports activities. Lack of detailed company information and contact data limits deeper business intelligence insights. The site maintains consistent branding and a professional appearance, supporting moderate trustworthiness in its market position.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly implemented, ensuring encrypted communications. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates room for improvement in mitigating common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected, and cookie consent mechanisms are in place, supporting privacy compliance efforts. The lack of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests limited preparedness for security incidents. Enhancing these areas would strengthen the overall security posture and compliance with regulations like GDPR.

Recommendations

  1. Implement comprehensive privacy and terms of service pages to improve compliance and user trust.
  2. Add essential security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against common attacks.
  3. Conduct regular security audits of third-party scripts and plugins to identify and mitigate vulnerabilities.
  4. Provide clear contact information including emails and phone numbers for business and security inquiries.
  5. Establish and publish a vulnerability disclosure policy and incident response plan to improve security transparency and readiness.

Technical notes

Notes

The website is built on WordPress CMS, utilizing standard web technologies including jQuery, Select2 for enhanced UI elements, Google Maps API for event location visualization, and AddThis for social sharing. The site loads external fonts from Google Fonts and integrates social media SDKs for Facebook and YouTube. Performance is moderate with no critical errors detected, and the site is mobile-optimized with responsive design elements. Accessibility is basic but could be improved with additional ARIA attributes and keyboard navigation enhancements. SEO is supported by proper meta tags and structured navigation. The absence of advanced frameworks or custom backend technologies suggests a straightforward technical infrastructure with opportunities for modernization and security hardening.
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.
