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

Vodáckanavigace.cz is a specialized Czech website providing detailed navigation, maps, and guides for water sports enthusiasts, particularly canoeists and kayakers navigating Czech rivers. The site offers comprehensive river kilometrage, information about rapids, campsites, rental services, and related amenities. It also supports a mobile Android application for offline use, enhancing user convenience. The business operates in a niche market with a focus on outdoor recreation and tourism within the Czech Republic. The website is well-branded and consistent, with partnerships evident through linked rental and sales companies. Technically, the site is built on ASP.NET Web Forms with Telerik UI components and uses older jQuery libraries. It integrates Google Analytics and Facebook SDK for tracking and social engagement. The site is mobile-optimized and provides a good user experience, though some technical debt is noted due to outdated libraries and lack of modern security headers. From a security perspective, the site uses HTTPS but lacks several security headers and explicit cookie consent mechanisms. No WHOIS data is available, which reduces domain trustworthiness, though the website content and partner links suggest legitimacy. No explicit security or incident response policies are published, indicating room for improvement in compliance and transparency. Overall, vodackanavigace.cz is a functional, content-rich site serving a specialized audience with good business credibility but could enhance its security posture and privacy compliance to align with best practices.

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.

Priority findings

8 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

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 targets water sports enthusiasts in the Czech Republic, offering detailed river navigation and related services. Its business model appears to be informational and service-oriented, supported by partnerships with boat rental companies and equipment sellers. The presence of a mobile app on Google Play indicates a multi-channel approach. The site is likely a small-sized operation focused on a niche market with strong local expertise. The partnership ecosystem includes rental and sales companies, enhancing service offerings. The lack of visible direct contact details on the homepage suggests a focus on online engagement and possibly centralized contact pages. The site’s market position is likely strong within its niche, with a loyal user base relying on up-to-date river data and navigation aids.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and no visible exposure of sensitive data. However, it lacks important security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options, which are critical for mitigating common web attacks. The use of an outdated jQuery version (1.11.0) poses potential vulnerabilities. No explicit privacy consent mechanisms or security policies are published, which may impact GDPR compliance. The absence of a security.txt or vulnerability disclosure page limits transparency and incident response readiness. Overall, while basic security measures are in place, there are notable gaps that should be addressed to improve resilience and compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Update third-party libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  3. Add explicit cookie consent banners and mechanisms to comply with GDPR and enhance user privacy transparency.
  4. Publish clear security and incident response policies, including a security.txt file and vulnerability disclosure guidelines.
  5. Enhance accessibility features and conduct regular security audits to maintain and improve security posture.

Technical notes

Notes

The website is built on ASP.NET Web Forms with Telerik UI components, indicating a mature but somewhat legacy technology stack. It uses jQuery 1.11.0, which is outdated and may introduce security risks. The site loads external resources from Google Fonts, Facebook SDK, and Google Analytics, integrating social and analytics capabilities. Performance is moderate, with mobile optimization rated good. SEO is supported by proper meta tags and Open Graph data. The site lacks modern CMS indications and appears custom-developed. Hosting provider details are not evident. There is opportunity to modernize the tech stack, improve performance, and enhance security configurations to reduce technical debt and improve user experience.
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.
