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

Duesenberg is a specialized manufacturer and retailer of premium musical instruments, primarily guitars, basses, lapsteels, amplifiers, and effect pedals. The company emphasizes German craftsmanship and collaborates with renowned artists to create signature instrument series. The website is professionally designed with excellent content quality, clear navigation, and mobile optimization, targeting musicians and guitar enthusiasts globally. Technically, the site uses modern frameworks such as Bootstrap and integrates Google Tag Manager for analytics, with a cookie consent mechanism ensuring privacy compliance. Security posture is good with HTTPS enforced, though some security headers are missing and no explicit security policies are published. The WHOIS data for the domain is missing or unavailable, which raises concerns about domain legitimacy despite the professional appearance of the site. Overall, the website presents a trustworthy and high-quality brand experience but would benefit from improved transparency in domain registration and contact information.

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

3 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 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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

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

Duesenberg occupies a niche market in the musical instrument retail sector, focusing on high-end guitars and related products. Their business model includes direct sales via a webstore and dealer network, supported by artist endorsements that enhance brand credibility. The company targets professional musicians and enthusiasts seeking quality and unique instrument designs. The website's content and multimedia presentations indicate a mature digital presence, though the absence of clear contact details and WHOIS transparency could impact customer trust. There is no evidence of parent or subsidiary companies, suggesting an independent operation. Marketing efforts leverage video content and Google Tag Manager analytics, with moderate user tracking balanced by GDPR-compliant privacy measures.

Security posture

The website demonstrates a solid security foundation with HTTPS enabled and a cookie consent mechanism in place, reflecting awareness of privacy regulations. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of published security policies or incident response contacts limits transparency and preparedness communication. The missing WHOIS data is a notable risk factor, potentially indicating privacy protection or registration issues. Overall, the security maturity is moderate to good but could be enhanced by implementing additional headers and publishing security documentation.

Recommendations

  1. Implement and configure security headers including CSP, HSTS, and X-Frame-Options to strengthen site security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Clarify domain registration details or ensure WHOIS data is publicly available to enhance trustworthiness.
  4. Add clear company contact information such as official emails and phone numbers on the website.
  5. Consider establishing a vulnerability disclosure program to encourage responsible reporting of security issues.

Technical notes

Notes

The website is built on a modern technology stack featuring Bootstrap 4 for responsive design, jQuery for scripting, and Google Tag Manager for analytics. It uses lazy loading for images (Lozad) and integrates multimedia content via YouTube iframes with privacy-conscious two-click consent. The site is mobile-optimized and accessible with good SEO practices including meta tags and Open Graph data. Hosting details are not explicitly identified. Performance is moderate, with potential improvements in loading speed by optimizing scripts and images further. The CMS is not clearly identified, suggesting a custom or proprietary solution. Overall, the technical infrastructure supports a professional and user-friendly experience but could benefit from enhanced security configurations and performance tuning.
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.
