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

11 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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

Radia.cz operates in the media sector, focusing on online streaming of radio and podcasts. Its business model likely relies on advertising revenue, supported by partnerships with ad networks like Adform and Google Adsense. The platform serves a general audience interested in Czech and Slovak music and audio content, leveraging a large catalog of stations and podcasts. The company maintains partnerships with related domains for radio creation and advertising. The long domain age and consistent branding indicate a mature operation with stable market presence. Growth opportunities include expanding mobile app usage and enhancing user engagement through personalized content.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced and use of service workers. Consent management for cookies is implemented via Didomi, aligning with GDPR requirements. No exposed sensitive data or vulnerable libraries were detected in the HTML content. 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 multiple third-party scripts necessitates ongoing security audits to mitigate supply chain risks. Overall, the security posture is adequate for the business type but could be enhanced by formalizing security governance and disclosure.

Recommendations

  1. Publish explicit security and incident response policies on the website to improve transparency and trust.
  2. Implement a security.txt file or vulnerability disclosure policy to encourage responsible reporting of security issues.
  3. Audit and monitor third-party scripts regularly to reduce supply chain risks.
  4. Enhance accessibility features to comply with standards and improve user experience for all users.
  5. Consider adding direct contact information such as company emails or phone numbers for support and security reporting.

Technical notes

Notes

The website uses a modern React-based frontend with asynchronous loading of scripts for analytics, advertising, and consent management. It employs service workers to improve performance and offline capabilities. The presence of multiple ad networks and tracking pixels indicates a monetization strategy reliant on advertising. SEO is supported by proper meta tags and Open Graph descriptions. Mobile optimization is good, with responsive design and mobile app promotion. Performance is moderate, with potential improvements by optimizing third-party script loading and caching strategies. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed in the HTML content.
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.
