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

Bandzone.cz is a well-established Czech online music community platform founded in 2005, serving as the largest hub for bands, DJs, MCs, and their fans in the Czech Republic. It offers extensive profiles, music streaming, concert listings, videos, and fan engagement features, positioning itself as a key player in the Czech music media sector. The platform monetizes primarily through advertising and promotional services, partnering with ticketing and music education providers. Technically, the site uses a custom CMS with legacy technologies such as jQuery 1.8.3, Firebase for authentication, and integrates Google Analytics and Facebook Pixel for tracking. While the site is functional and content-rich, it shows moderate performance and basic mobile optimization.

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

8 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. Security headers

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

Bandzone.cz holds a strong market position as the largest Czech music community platform, with over 46,000 registered bands and 225,000 fans. Its competitive advantage lies in its comprehensive music database, community features, and partnerships with ticketing and music education services. The business model focuses on advertising revenue and promotional services for bands and events. The target audience includes Czech and Slovak music fans and artists, with growth potential through enhanced digital services and mobile experience. The partnership ecosystem includes smsticket.cz, artmasteracademy.cz, and musicserver.cz, which complement its offerings.

Security posture

The website enforces HTTPS and uses Google reCAPTCHA to protect forms, indicating a baseline security posture. However, the use of an outdated jQuery version introduces known vulnerabilities, and the absence of security headers such as Content-Security-Policy and X-Frame-Options weakens defense-in-depth. No explicit security policies or incident response contacts are published, which limits transparency and preparedness. The site collects extensive user data via tracking pixels and analytics, but privacy compliance is basic, with only a cookie consent banner and terms of service visible. Overall, the security maturity is moderate but requires improvements to reduce risk exposure.

Recommendations

  1. Upgrade jQuery and other JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  3. Publish a dedicated security policy and provide clear incident response contact channels to improve transparency and trust.
  4. Enhance mobile optimization and accessibility to improve user experience and compliance with modern standards.
  5. Review and improve privacy compliance measures, including detailed privacy policy and data retention disclosures.

Technical notes

Notes

The website runs on a custom CMS with legacy front-end technologies including jQuery 1.8.3 and jQuery UI, combined with Firebase for authentication and Google/Facebook analytics and advertising integrations. The site loads multiple external scripts and stylesheets, some asynchronously, which helps performance but also increases third-party dependencies. The absence of modern frameworks or CMS platforms suggests technical debt and potential maintenance challenges. Performance is moderate with room for improvement in mobile responsiveness and accessibility. Security best practices are partially implemented but lack comprehensive coverage.
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.
