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

Leťánek.cz is the website of Spolek RC Leťánek z.s., a small non-profit family center based in the Czech Republic, founded in 2009. The organization focuses on providing community and recreational activities for families, parents, and children, including events like the Pohádkový les. The website serves as an informational portal with basic content about upcoming events and organizational details. Technically, the site uses legacy technologies such as jQuery 1.3.2 and Google Analytics for tracking, but lacks modern CMS or frameworks. The site is accessible over HTTPS but lacks advanced security headers and cookie consent mechanisms, which are important for GDPR compliance. The website is not mobile optimized and has basic SEO and accessibility features. No contact emails or phone numbers are directly visible on the main page, which limits direct communication channels. The domain registration data is consistent with the organization's profile and shows a long-standing presence since 2009, supporting legitimacy.

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

11 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 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 organization operates as a local non-profit entity serving families in the Czech Republic, particularly around Karlík. Its business model is community-focused, offering events and courses for children and parents. The website links to partner sites such as kudyznudy.cz, indicating collaboration within local tourism and family activity networks. Revenue streams are likely based on donations, event fees, or grants typical for non-profits. The site’s modest digital presence and basic technical infrastructure suggest limited investment in digital transformation. Growth opportunities could include enhanced online engagement and improved digital services. The partnership ecosystem appears limited but relevant to local community activities.

Security posture

The website’s security posture is basic. HTTPS is enabled, which is mandatory, but no additional security headers like Content-Security-Policy or X-Frame-Options are detected. The use of an outdated jQuery version (1.3.2) introduces potential vulnerabilities that could be exploited. No visible forms reduce attack surface but also limit user interaction. The absence of cookie consent mechanisms and detailed security policies indicates partial GDPR compliance. Incident response and vulnerability disclosure information are not present, which may impact trust and readiness. Overall, the site requires updates to libraries, implementation of security headers, and enhanced privacy controls to improve security maturity.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to current secure versions to mitigate known vulnerabilities.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  3. Add a cookie consent banner and detailed cookie policy to comply fully with GDPR and EU cookie laws.
  4. Improve mobile responsiveness and accessibility to enhance user experience across devices.
  5. Publish clear contact information and consider adding a security or abuse contact channel to improve transparency and incident response readiness.

Technical notes

Notes

The website is built with static HTML and uses an outdated jQuery 1.3.2 library, which is a significant technical debt and security risk. Google Analytics is integrated for visitor tracking. No modern CMS or frameworks are detected, indicating a simple, possibly manually maintained site. The site uses basic meta tags but lacks Open Graph or JSON-LD structured data, limiting SEO and social media integration. Hosting details are minimal but the domain uses REG-WEB4U registrar and pipni.cz nameservers. Performance is moderate but mobile optimization is poor, which may affect accessibility and user engagement. The site would benefit from modernization including responsive design, updated tech stack, and improved SEO practices.
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.
