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

TV Natura is a small Czech internet television platform focused on nature, environmental awareness, and community engagement. The website offers live streaming, archived videos, articles, and opportunities for user-generated content. The business operates as a small media entity with a non-profit or community-supported model, recently transitioning to a paid membership platform due to regulatory and financial challenges. Technically, the site uses modern web technologies including HTTPS, Bootstrap, and integrates Google Analytics and Facebook Pixel for tracking. The security posture is moderate with HTTPS enforced but lacks advanced security headers and explicit security policies. Privacy compliance is basic with a cookie consent banner and a privacy policy page, but no terms of service or incident response information is found. The absence of WHOIS data reduces domain trustworthiness, but the website content and contact information appear legitimate. Overall, the site provides a good user experience with relevant content for its target audience but would benefit from enhanced security and 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

TV Natura occupies a niche position in the Czech media market as an internet-based TV channel focused on nature and social topics. Its competitive advantage lies in community involvement and unique content. The business model relies on voluntary support and paid memberships on a new platform, indicating a shift from free licensed broadcasting. The target customers are environmentally conscious individuals and community members interested in sustainable living. Growth indicators include active content creation and community engagement. Partnerships include the Herohero platform for paid memberships. Strategic observations suggest the need to strengthen compliance and security to maintain trust and expand reach.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and cookie consent implemented. However, it lacks important security headers such as Content Security Policy, HSTS, and X-Frame-Options. No vulnerability disclosure or incident response policies are present, which could hinder timely handling of security incidents. The use of third-party tracking scripts introduces potential privacy risks. There is no evidence of exposed sensitive data or critical vulnerabilities in the HTML content. Compliance with GDPR is basic but present. Overall, the security posture is adequate for a small media site but requires improvements to meet higher standards and regulatory requirements.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Develop and publish detailed privacy and security policies, including GDPR compliance statements and data retention policies.
  3. Establish a vulnerability disclosure program and incident response contact to improve security transparency and readiness.
  4. Regularly audit and update third-party scripts to minimize privacy and security risks.
  5. Enhance accessibility and SEO features to improve user experience and search engine visibility.

Technical notes

Notes

The website uses a modern tech stack with Bootstrap for responsive design, embedded YouTube for video streaming, and integrates Google Analytics and Facebook Pixel for analytics and marketing. The site is served over HTTPS, ensuring encrypted communication. Performance is moderate with some room for optimization. Accessibility is basic but functional. The absence of a detected CMS suggests a custom or static site architecture. Hosting provider details are not available from the data. The site includes a cookie consent banner indicating awareness of privacy regulations. Technical risks include missing security headers and reliance on multiple third-party scripts which could introduce vulnerabilities.
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.
