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

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"

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 holds a dominant position as the national public broadcaster in the Czech media landscape. Its business model is primarily funded through TV license fees and government support, focusing on serving the Czech-speaking population with diverse programming. The website supports this model by offering live streaming, video archives, and program information, targeting a broad audience including general viewers, sports fans, children, and educational users. The presence of multiple branded channels and official social media accounts reflects a strong partnership ecosystem and brand consistency. The site also supports career opportunities and e-commerce through affiliated domains. Growth indicators include active content updates and integration of modern marketing and analytics tools.

Security posture

The website employs HTTPS with a strong SSL configuration, uses a consent management platform to comply with GDPR, and integrates reputable analytics and tracking services with user consent. However, it lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which are recommended best practices. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site does not publish a security.txt file or provide explicit incident response contacts, which could enhance transparency and readiness. Overall, the security posture is good but could be strengthened by adopting additional security headers and formal vulnerability disclosure mechanisms.

Recommendations

  1. Implement and explicitly configure security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Provide clear incident response contact information on the website.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance documentation of data retention policies related to analytics and user data.

Technical notes

Notes

The website uses a combination of jQuery, Modernizr, and custom JavaScript for UI and functionality, supported by Google Tag Manager for analytics and marketing tags. It integrates Microsoft Clarity and Gemius Audience for user behavior tracking. The site is mobile-optimized with responsive CSS and accessible navigation. Performance is moderate, with room for optimization in loading times and script management. No CMS was explicitly detected, suggesting a custom or proprietary platform. The technical stack is modern but could benefit from further modernization and performance tuning 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.
