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

The website www.mujrozhlas.cz serves as the primary audio portal for Český rozhlas, the Czech public radio broadcaster. It offers a wide range of audio content including podcasts, interviews, audiobooks, fairy tales, sports coverage, radio plays, and historical recordings. The portal targets the Czech-speaking general public interested in diverse audio media. The site is well-branded and positioned as the largest audio portal on the Czech internet, reflecting a strong market presence in the media sector. Technically, the site is built on Drupal 10 CMS and utilizes modern JavaScript libraries and analytics tools such as Gemius and Google Tag Manager. The site demonstrates good mobile optimization, accessibility, and SEO practices, contributing to a positive user experience. Cookie consent mechanisms are implemented, indicating some level of privacy compliance. From a security perspective, the site enforces HTTPS and employs cookie consent but lacks explicit security headers and publicly available privacy or security policies. The absence of WHOIS data reduces trust signals, although the site's content and branding strongly suggest legitimacy. No WAF or blocking mechanisms were detected, and no vulnerabilities or adult content were found. Overall, the site presents a professional and trustworthy platform for audio content distribution but would benefit from enhanced transparency in privacy policies, security disclosures, and WHOIS information to improve compliance and trustworthiness.

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

      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

Český rozhlas operates www.mujrozhlas.cz as a public broadcasting audio portal, offering a comprehensive catalog of spoken-word content. The business model focuses on content distribution rather than direct monetization, serving a broad audience in the Czech Republic. The portal leverages its position as the largest Czech audio platform to maintain competitive advantage. Partnerships with analytics providers like Gemius and Google indicate a data-driven approach to audience measurement. The absence of explicit contact or business registration details on the site suggests a focus on content delivery over direct commercial engagement. Growth indicators include extensive content variety and modern platform adoption. Strategic observations highlight the importance of improving transparency and compliance documentation to align with evolving regulatory expectations.

Security posture

The security posture of www.mujrozhlas.cz is moderate. HTTPS is enforced, and cookie consent is implemented, which are positive indicators. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap in defense-in-depth. No vulnerability disclosure policy or security.txt file is present, limiting the ability for external parties to report security issues responsibly. The absence of contact information for incident response or data protection officers further reduces readiness for security incidents. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the site would benefit from enhanced security best practices and transparency to strengthen its security maturity and compliance posture.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Implement and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  3. Add standard security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to improve protection against common web attacks.
  4. Provide clear contact information for security incidents and data protection officer to enhance incident response capabilities.
  5. Ensure WHOIS data is complete and publicly available to improve domain registration transparency and trust.

Technical notes

Notes

The website is built on Drupal 10, a modern and widely supported CMS, indicating a solid technical foundation. The use of JavaScript libraries such as Modernizr and analytics tools like Gemius and Google Tag Manager reflects a contemporary tech stack. The site includes responsive design features and accessibility considerations, contributing to a good user experience across devices. Performance is moderate, with some external scripts potentially impacting load times. The absence of explicit security headers and incomplete WHOIS data represent technical risks. Overall, the infrastructure is robust but could be improved by addressing security headers and enhancing transparency in domain registration.
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.
