JBL Synthesis is a premium brand specializing in high-end home theater audio systems, offering turnkey solutions that combine advanced electronics and loudspeakers tailored to individual room acoustics.

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 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

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

JBL Synthesis holds a strong market position in the premium home theater audio segment, leveraging Harman International's brand portfolio and dealer network. The business model focuses on B2C sales via authorized dealers and installers, emphasizing custom system design and expert calibration. The website supports this with detailed product categories, dealer locators, and brand consistency. The presence of sister brands and parent company links indicates a robust partnership ecosystem. The company targets affluent consumers and professionals seeking high-fidelity audio solutions. Growth potential is supported by digital marketing tools and analytics integration, though direct contact details are limited to forms, suggesting a controlled customer engagement approach.

Security posture

The website employs HTTPS with a good SSL configuration and integrates cookie consent management via OneTrust, reflecting compliance with GDPR and privacy best practices. Security headers are not explicitly visible in the HTML but may be implemented at the server level. No vulnerabilities or exposed sensitive data were detected in the content. However, the lack of a public security policy or incident response contact reduces transparency. The use of third-party scripts like Google Tag Manager and CQuotient introduces potential risk vectors that require ongoing monitoring. Overall, the security posture is solid but could be enhanced by publishing explicit security policies and providing direct security contact channels.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and incident response procedures.
  2. Implement and explicitly declare security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide direct contact information for security incidents, such as a security@ or abuse@ email address.
  4. Regularly audit third-party scripts and dependencies to mitigate supply chain risks.
  5. Verify and update WHOIS registration information to ensure domain legitimacy and transparency.

Technical notes

Notes

The website is built on Salesforce Commerce Cloud, leveraging modern JavaScript libraries and responsive CSS for a good user experience across devices. Performance is moderate with asynchronous loading of analytics and cookie scripts. SEO is supported by proper meta tags and structured navigation. Accessibility features are present, including ARIA labels and keyboard navigability. The technical infrastructure is robust for an e-commerce platform but could benefit from enhanced security header implementation and performance optimization. Hosting details are not explicitly identified but likely managed by Salesforce infrastructure.
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.
