Rádio Krokodýl operates as a leading regional radio station serving Brno and the South Moravia region in the Czech Republic. The website offers a comprehensive range of services including live radio streaming, local news, contests, and advertising opportunities. It targets local residents and businesses seeking regional media exposure. The site is professionally designed with consistent branding and clear navigation, supporting a positive user experience. Technically, the website employs modern web technologies such as the Uikit framework, Google Tag Manager for analytics and marketing, and includes a cookie consent mechanism compliant with basic GDPR requirements. The site is mobile-optimized and performs moderately well, though some improvements in accessibility and security headers could enhance its robustness. From a security perspective, the site uses HTTPS and secure login forms with CSRF protection. However, the absence of WHOIS data and missing privacy policy page represent compliance and trust gaps. No critical vulnerabilities or malware indicators were found, but adding security headers and explicit privacy documentation is recommended. Overall, the website presents a credible and professional digital presence for Rádio Krokodýl, though it should address privacy compliance and domain registration transparency to strengthen trust and regulatory adherence.

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

7 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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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 Content-Security-Policy header

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 · found on this site
  • 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

Rádio Krokodýl holds a strong market position as the most listened-to regional radio in its area, leveraging local content and community engagement through contests and events. Its business model is primarily advertising-driven, targeting local businesses and listeners. The company maintains active social media channels to extend its reach and engagement. The website content and structure indicate a medium-sized enterprise with a focus on regional media services. The partnership with IMPnet for web development suggests a professional operational approach. Growth indicators include frequent news updates and active contest promotions, supporting audience retention and advertiser interest.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and secure login mechanisms including social login options. The presence of a cookie consent banner indicates awareness of privacy regulations. However, the lack of security headers such as Content-Security-Policy and HSTS reduces the overall security posture. The missing WHOIS data and privacy policy page are notable compliance gaps. No exposed sensitive data or vulnerable libraries were detected. Incident response and vulnerability disclosure mechanisms are not evident, suggesting areas for improvement in security governance and transparency.

Recommendations

  1. Implement and publish a comprehensive privacy policy to ensure GDPR compliance and user trust.
  2. Add essential security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and enable HSTS.
  3. Investigate and resolve the missing WHOIS data issue to improve domain registration transparency and trustworthiness.
  4. Establish a vulnerability disclosure policy and incident response contact to enhance security posture and stakeholder confidence.
  5. Regularly audit third-party scripts and tracking tools to minimize security risks and ensure privacy compliance.

Technical notes

Notes

The website uses a modern front-end framework (Uikit) and integrates Google Tag Manager for analytics and marketing. It includes a cookie consent mechanism with granular user controls. The site is mobile responsive and features multimedia content such as audio streaming and interactive elements. The CMS is not explicitly identified, suggesting a custom or proprietary solution. Performance is moderate with some scope for optimization. Accessibility features are basic but present. The site lacks some advanced SEO and security best practices such as security headers and structured data markup. Overall, the technical infrastructure supports the business needs but could benefit from modernization and enhanced security controls.
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.
