Medium risk. 4 critical or high findings in GDPR outside view and SSL/TLS.

Security score

75/100

Risk levelMedium

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

Český rozhlas is the Czech Republic's public radio broadcaster, offering a comprehensive online portal with news, live radio streaming, podcasts, cultural content, and audiobooks. The website is professionally designed, mobile-optimized, and provides extensive multimedia content targeting the general public interested in news and culture. Technically, the site is built on Drupal 7 with modern web technologies and integrates Google Tag Manager and advertising services. Security posture is good with HTTPS enforced, though some security headers could be improved. Privacy compliance is basic with a cookie consent mechanism but no explicit privacy policy detected. WHOIS data is missing, which slightly impacts trust but the site’s branding and content strongly indicate legitimacy.

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

4 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, 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

The portal serves as a central hub for Český rozhlas's multiple radio stations and content platforms, including iRozhlas, mujRozhlas, and Radiotéka. It operates as a public service media entity with a large audience in the Czech Republic. The business model is primarily public broadcasting funded by public fees and government support, supplemented by advertising. The site’s ecosystem includes multiple branded subdomains and partner sites, indicating a well-established media network. The absence of explicit contact details and privacy policy on the main portal suggests areas for improvement in transparency and user trust.

Security posture

The website enforces HTTPS and uses Google Tag Manager and DoubleClick for advertising and analytics. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options is a gap. There is no visible incident response or security policy information on the site. The missing WHOIS data reduces domain trustworthiness slightly but does not indicate malicious activity. Overall, the security posture is moderate to good but could benefit from enhanced header policies and clearer security documentation.

Recommendations

  1. Publish a clear and comprehensive privacy policy page linked from the main portal.
  2. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide explicit contact information including emails and phone numbers for user support and security incident reporting.
  4. Regularly update Drupal core and modules to mitigate potential vulnerabilities.
  5. Improve transparency by publishing security policies and incident response procedures.

Technical notes

Notes

The site uses Drupal 7 CMS with multiple custom and contributed modules, including advanced aggregation and lazy loading techniques. It integrates Google Tag Manager and Google Analytics for tracking and advertising. The site is mobile-optimized and accessible with good SEO meta tags and Open Graph data. Performance is moderate, with asynchronous loading of scripts. The absence of WHOIS data and some missing security headers are technical risks. Overall, the infrastructure is stable but could be modernized with updated CMS versions and enhanced security configurations.
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.
