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

Music City, operated by AudioMaster, a. s., is a Czech Republic-based e-commerce retailer specializing in musical instruments, sound and lighting technology, DJ equipment, and home recording gear. The company maintains a strong market presence with multiple physical stores in Prague, Brno, and Uherské Hradiště, complemented by a comprehensive online store. Their business model focuses on providing musicians and music enthusiasts with a wide range of products at competitive prices, supported by free shipping and a three-year warranty, enhancing customer trust and satisfaction. Technically, the website employs modern web technologies including JavaScript, Google Tag Manager, Cookiebot for cookie consent management, and analytics tools such as Google Analytics and Hotjar. The site is mobile-optimized and demonstrates good SEO and accessibility practices. However, there is room for improvement in security headers implementation and further hardening of form security. From a security perspective, the site uses HTTPS and has a robust cookie consent mechanism, indicating compliance with GDPR and privacy best practices. No critical vulnerabilities or exposed sensitive data were detected. The absence of WHOIS registration data is a notable concern, potentially impacting domain trustworthiness, but the visible business information and contact details mitigate this risk somewhat. Overall, Music City presents a professional and trustworthy online presence with a solid business foundation. Strategic improvements in domain registration transparency and enhanced security headers would further strengthen their security posture and 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

5 findings rated critical or high. Fix these first.

  1. 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

      Prevents clickjacking attacks

      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';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  3. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

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

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

Music City operates in the retail sector, targeting musicians and music instrument buyers primarily in the Czech Republic. Their competitive advantage lies in a broad product offering, physical store presence, and customer-centric policies like extended warranties and free shipping. Revenue streams are primarily from direct sales of musical instruments and related equipment. The company leverages partnerships with affiliate networks and advertising platforms such as Glami, Heureka, Adform, and Dognet to expand market reach. Growth indicators include multi-location stores and extensive digital marketing integration. The partnership ecosystem supports both marketing and analytics, enhancing operational insights and customer engagement.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and a comprehensive cookie consent mechanism aligned with GDPR requirements. The use of reputable third-party analytics and marketing tools is balanced with user privacy considerations. However, the lack of visible security headers such as Content-Security-Policy and X-Frame-Options suggests potential areas for improvement. No signs of malware, phishing, or exposed sensitive data were found. Incident response and security policy documentation are not publicly available, indicating an opportunity to enhance transparency and preparedness. Overall, the security maturity is good but could benefit from formalized policies and technical hardening.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Investigate and resolve the absence of WHOIS registration data to improve domain legitimacy and trust.
  3. Enhance form security by adding anti-CSRF tokens and validating all user inputs server-side.
  4. Publish clear security and incident response policies to increase transparency and readiness.
  5. Regularly audit third-party scripts and dependencies to identify and remediate potential vulnerabilities.

Technical notes

Notes

The website uses a modern JavaScript-based front end with integration of Google Tag Manager, Cookiebot for consent management, and analytics tools like Google Analytics and Hotjar. The site is mobile-optimized and includes responsive design elements. Performance is moderate, with potential for optimization in script loading and caching. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The technical stack supports good SEO and accessibility, but security headers are missing, which is a technical debt. The site uses multiple external domains for marketing and analytics, which requires ongoing monitoring for privacy 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.
