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

5 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Česká televize operates as a public broadcaster funded by the Czech government, offering multiple channels and digital services including CT24. The business model focuses on public service media, delivering news and cultural content to the Czech population. The company holds a strong market position as the primary national broadcaster with extensive reach and brand recognition. Its ecosystem includes several subsidiary domains for specialized content such as sports and children's programming. The website's content and structure reflect a focus on transparency, trust, and user engagement. Partnerships and integrations with analytics and marketing tools support audience insights and content optimization. Growth indicators include continuous content updates and multimedia offerings. Strategic observations highlight the importance of maintaining security transparency and enhancing user privacy controls.

Security posture

The website employs HTTPS with strong SSL configuration and standard security headers, indicating a solid baseline security posture. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the absence of publicly available security policies, incident response contacts, or vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. The use of third-party analytics and marketing scripts introduces moderate tracking but appears compliant with privacy regulations. Overall, the security maturity is good for a public media site, but formalizing security governance documentation and incident response channels would enhance trust and preparedness.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency.
  2. Implement and publicize a vulnerability disclosure program, including a security.txt file.
  3. Add explicit security contact channels such as security@ or abuse@ email addresses.
  4. Regularly audit and update third-party scripts to minimize potential vulnerabilities.
  5. Maintain accurate and publicly accessible WHOIS registration data to enhance legitimacy.

Technical notes

Notes

The website is built on a modern React and Next.js framework, supporting server-side rendering and optimized performance. It uses CSS for styling and integrates analytics tools like Google Tag Manager and Microsoft Clarity for user behavior tracking. The site is mobile-optimized with responsive design and accessibility features such as focus-visible states and semantic HTML. Performance is moderate, with potential improvements in loading speed and resource optimization. The absence of a detected CMS suggests a custom or proprietary content management solution. Hosting details are not explicitly identified, but the infrastructure supports a high-traffic public media portal. Technical risks are minimal, though continuous monitoring of third-party dependencies is advised to mitigate supply chain risks.
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.
