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

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

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

The business operates in the media sector focusing on regional radio broadcasting with revenue streams likely from advertising and promotional contests. Its competitive advantage lies in its strong regional brand recognition and extensive FM coverage across multiple cities. The business model emphasizes community engagement through contests and local news, targeting residents of Brno and South Moravia. Partnerships with web development firms and streaming services enhance its digital presence. Growth indicators include active social media followings and regular content updates. Strategic observations suggest potential for expanding digital advertising and improving direct contact channels for enhanced customer engagement.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and a comprehensive cookie consent mechanism indicating GDPR compliance. However, the lack of visible security headers such as Content-Security-Policy and absence of a published security policy or incident response contacts reveal gaps in security best practices. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The site would benefit from implementing a security.txt file and enhancing transparency around security incident handling. Overall, the security posture is adequate for a media website but could be strengthened to mitigate risks and improve trust.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact information to improve transparency and readiness.
  3. Add a security.txt file at the root domain to facilitate responsible vulnerability disclosure.
  4. Enhance contact information visibility on the website to improve user trust and business credibility.
  5. Regularly audit and update third-party scripts and tracking tools to minimize security risks and ensure compliance.

Technical notes

Notes

The website is built using the Uikit front-end framework and jQuery, with Google Tag Manager integrated for analytics and marketing tracking. The site is mobile responsive and optimized for user experience with clear navigation and structured content. Performance is moderate, with potential improvements in loading speed through optimization of assets and scripts. The CMS or backend platform is not explicitly identified, suggesting a custom or proprietary solution. Accessibility features are basic but present. Technical risks include reliance on third-party scripts and lack of advanced security headers. Opportunities exist to modernize the tech stack and improve SEO and accessibility 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.
