Risk levelLow

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

Crown is a professional audio brand specializing in power amplifiers and network audio solutions, operating under the Harman International umbrella. The website presents a comprehensive catalog of products, detailed technical information, and support resources targeting professional audio engineers and commercial audio markets. The brand is well-established with a consistent and professional online presence, supported by structured data and social media integration. Technically, the website uses a modern technology stack including jQuery, Foundation framework, and integrates analytics tools such as Google Analytics and HubSpot. The site is mobile optimized and performs moderately well, with good SEO and accessibility basics. Security measures include HTTPS enforcement and CSRF protection, though some security headers are missing. The security posture is solid with no visible vulnerabilities or exposed sensitive data. Privacy compliance is evident with a clear privacy policy, cookie consent mechanisms, and GDPR considerations. However, the absence of WHOIS data for the domain introduces some uncertainty regarding domain registration legitimacy, though the association with Harman mitigates this concern. Overall, the website is professional, secure, and trustworthy, serving a specialized B2B audience effectively. Strategic improvements in security headers and transparency around incident response could further enhance trust and compliance.

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

2 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

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

Crown holds a strong market position within the professional audio amplification industry as part of Harman International. Its business model focuses on manufacturing and selling high-quality power amplifiers and network audio solutions, supported by software, training, and technical support services. The target customers are professional audio engineers, installers, and commercial audio integrators. The company leverages a broad partnership ecosystem including Harman's other brands and service portals. The website content and structure indicate a mature digital presence with clear branding and consistent messaging, supporting growth and customer engagement.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, CSRF tokens in forms, and no visible exposure of sensitive data. Use of modern JavaScript libraries is evident, though some libraries are slightly outdated (e.g., jQuery 2.2.4). Security headers like Content-Security-Policy and X-Frame-Options are not detected and should be implemented to harden the site further. No explicit incident response or vulnerability disclosure information is found, which is a gap in transparency. Privacy policies and cookie consent mechanisms are in place, supporting GDPR compliance. Overall, the site is secure but could improve in security header implementation and incident response visibility.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Update third-party JavaScript libraries to latest stable versions to mitigate potential vulnerabilities.
  3. Publish a security.txt file or dedicated security page detailing vulnerability disclosure and incident response procedures.
  4. Enhance accessibility features to meet higher standards for users with disabilities.
  5. Monitor and resolve the missing WHOIS data issue to improve domain registration transparency and trust.

Technical notes

Notes

The website is built on a solid technical foundation using the Foundation CSS framework and jQuery libraries. It integrates Google Analytics and HubSpot for marketing and analytics purposes. The site is hosted on Harman's CDN infrastructure, ensuring reliable delivery. Performance is moderate with room for optimization. Mobile responsiveness is good, and SEO best practices are followed with proper meta tags and structured data. Some technical debt is noted in the use of older jQuery versions. Accessibility is basic but could be improved. Overall, the technical implementation supports the business goals effectively with opportunities for modernization.
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.
