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

Vodácká navigace is a specialized Czech website providing detailed river navigation guides, kilometrage, maps, and related services for water sports enthusiasts. It offers comprehensive information on Czech rivers, including weirs, campsites, pubs, and rental services, supported by a mobile Android app for offline use. The site targets the niche market of Czech paddlers and outdoor water sports participants, positioning itself as a trusted local guide with partnerships from rental companies and data providers. Technically, the website is built on ASP.NET WebForms with Telerik UI components and uses legacy jQuery, Google Analytics, and Facebook SDK for analytics and social integration. While the site is accessible and well-structured with good mobile optimization, it lacks modern security headers and explicit cookie consent mechanisms. The absence of WHOIS data reduces domain trustworthiness, though the content and partnerships suggest legitimacy. No direct contact emails or phone numbers are visible on the main page, with contact facilitated via a dedicated page. Overall, the site is functional and relevant but would benefit from enhanced security and privacy compliance measures.

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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 serves a focused market segment of Czech water sports enthusiasts by providing navigation and kilometrage data for over 20 rivers, enriched with thousands of points of interest and photos. Its business model revolves around offering free online content supplemented by a free Android app, and monetization likely comes from partnerships with rental companies, travel agencies, and equipment sellers. The presence of partner logos and data sharing with mapy.cz indicates a collaborative ecosystem. The site is small in scale but holds a strong niche position. Growth potential exists through expanding river coverage and enhancing mobile app features. The lack of explicit business registration or company details limits transparency but does not detract from its operational presence.

Security posture

The website uses HTTPS as indicated by meta tags and external resource URLs, but no explicit security headers were detected in the HTML content. The use of an outdated jQuery version (1.11.0) poses potential security risks. No visible vulnerabilities or exposed sensitive data were found in the source. The site lacks published security policies, incident response contacts, or vulnerability disclosure programs, which are important for mature security posture. Cookie policy exists but without a consent mechanism, indicating partial privacy compliance. Overall, the security posture is moderate but could be significantly improved by updating libraries, adding security headers, and publishing security-related policies.

Recommendations

  1. Implement modern security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to enhance protection.
  2. Upgrade jQuery and other JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  3. Add a visible cookie consent banner to comply with GDPR and improve user privacy transparency.
  4. Publish a clear security policy and incident response contact information to build trust and readiness.
  5. Enhance accessibility features and conduct regular security audits to maintain compliance and security hygiene.

Technical notes

Notes

The website is built on ASP.NET WebForms with Telerik UI controls, indicating a mature but somewhat legacy technology stack. It uses jQuery 1.11.0, which is outdated and may contain vulnerabilities. The site loads Google Fonts, Facebook SDK, and Google Analytics scripts asynchronously, which is good for performance. Mobile optimization is good, supported by a dedicated Android app. SEO is supported by meta tags and Open Graph data. The site performance is moderate, with room for improvement in modernizing the tech stack and optimizing resource loading. No CMS was detected, suggesting a custom or in-house solution. Hosting provider details are not available from the content. Overall, the technical infrastructure is functional but could benefit from 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.
