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

The website www.nationalgeographic.cz is a localized Czech version of the globally recognized National Geographic brand, offering rich content focused on science, nature, history, travel, and photography. It serves a general audience interested in educational and informative media content. The site demonstrates a mature digital presence with modern web technologies, including JavaScript frameworks, analytics, and advertising integrations. While the site uses HTTPS and includes privacy consent mechanisms, it lacks explicit privacy policy and terms of service pages in the provided content, which slightly impacts privacy compliance scores. Security headers are partially implemented but could be improved to enhance protection against common web threats. The absence of WHOIS data suggests privacy protection for the domain registration, which is typical for media websites and does not detract from its legitimacy. Overall, the site is professional, trustworthy, and well-optimized for user experience and SEO.

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

7 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

    • 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

  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 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

National Geographic Czech Republic operates as a major media publisher in the Czech market, leveraging the strong international brand to deliver high-quality editorial content. Its business model relies on content publishing supported by advertising revenue, as evidenced by multiple ad network integrations. The target audience includes science enthusiasts, travelers, and history buffs. The site’s partnership ecosystem includes major advertising and analytics providers such as Google, Facebook, Gemius, and Seznam. The lack of explicit company contact information and privacy policies suggests an opportunity to improve transparency and user trust. The site’s content quality and branding consistency position it well in the competitive media landscape.

Security posture

The website enforces HTTPS and uses several security best practices, including privacy consent SDKs and no visible exposure of sensitive data. However, it lacks some important security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security, which are recommended to mitigate risks such as clickjacking, cross-site scripting, and downgrade attacks. No vulnerabilities or malware indicators were detected in the HTML content. The absence of published security policies or incident response contacts limits the site’s readiness for security incident management. Overall, the security posture is good but can be enhanced with additional headers and transparency.

Recommendations

  1. Publish a comprehensive privacy policy page clearly linked from the homepage.
  2. Implement and enforce Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security headers.
  3. Add visible contact information for security incidents and general inquiries to improve transparency.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks.
  5. Consider publishing a security.txt file or vulnerability disclosure policy to encourage responsible reporting.

Technical notes

Notes

The website uses a modern tech stack including HTMX for dynamic content loading, Tailwind CSS for styling, and integrates multiple third-party services for analytics and advertising. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, likely influenced by multiple external scripts and ad networks. SEO is well addressed with proper meta tags, Open Graph, and JSON-LD structured data. There is no clear CMS identified from the HTML, suggesting a custom or proprietary platform. Hosting provider details are not evident from the content. Technical risks include reliance on multiple third-party scripts which could impact performance and privacy if not managed carefully.
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.
