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

Radioteka.cz is a Czech e-commerce platform specializing in the sale of audiobooks, music, books, CDs, DVDs, and sheet music. The website targets Czech-speaking customers interested in digital and physical media content, offering products primarily in MP3 and FLAC formats. The business operates under the name Radioservis a.s., a recognized entity in the Czech media sector. The platform provides audio previews and a well-structured catalog, enhancing user experience and engagement. Technically, the website employs modern JavaScript libraries such as jQuery and jPlayer, integrates Google Tag Manager for analytics, and uses HTTPS to secure communications. The site is mobile-optimized and features a clear navigation structure, although some accessibility features and security headers could be improved. Privacy compliance is basic, with a consent mechanism denying tracking by default but lacking explicit privacy and cookie policy pages. From a security perspective, the site enforces HTTPS and restricts tracking by default, which is positive. However, the absence of security headers and lack of published security policies or incident response contacts indicate room for improvement. The missing WHOIS data for the domain is a concern, as it limits the ability to verify domain legitimacy and ownership, impacting overall trust. Overall, Radioteka.cz presents as a professional and trustworthy media e-commerce platform with good content quality and user experience. Strategic improvements in transparency, security headers, and domain registration verification would enhance its security posture and business credibility.

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

6 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

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

Radioteka.cz holds a solid position in the Czech media market, focusing on audiobooks and related media products. Its business model revolves around direct sales of digital and physical media, catering to a niche audience interested in spoken word content, classical and popular music, and literature. The platform's integration with Radioservis a.s. suggests established industry relationships and content sourcing. Revenue streams likely include direct product sales and possibly partnerships with content producers. The website's marketing ecosystem includes Seznam.cz and Google Tag Manager, indicating active digital marketing efforts. Growth potential exists through expanding content offerings and improving privacy and security transparency.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and default denial of tracking consent, which aligns with privacy best practices. However, the lack of security headers such as Content-Security-Policy and absence of published security policies or incident response contacts limit its security posture. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The missing WHOIS data raises concerns about domain registration legitimacy, which should be addressed to strengthen trust. Compliance with GDPR is implied but not explicitly documented. Incident response readiness and security culture indicators are not evident from the content.

Recommendations

  1. Publish comprehensive privacy and cookie policy pages to enhance transparency and GDPR compliance.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Verify and update WHOIS domain registration information to ensure legitimacy and improve trust.
  4. Provide clear contact information for security incidents and consider publishing a vulnerability disclosure policy or security.txt file.
  5. Enhance accessibility features and conduct regular security audits to maintain a strong security posture.

Technical notes

Notes

The website uses a modern JavaScript stack with jQuery and jPlayer for media playback, supported by Google Tag Manager and Seznam.cz tracking scripts. The site is responsive and optimized for mobile devices, with good SEO practices including meta tags and Open Graph data. Performance is moderate, with potential improvements in loading speed and accessibility. The absence of a detected CMS suggests a custom or proprietary platform. Hosting provider details are not evident. Technical debt appears low, but security header implementation and privacy documentation require attention to reduce risks and improve compliance.
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.
