Changzhou E-Sound Electronics Co.,Ltd · Manufacturing · China

Medium risk. 5 critical or high findings in GDPR outside view and SSL/TLS.

Security score

70/100

Risk levelMedium

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

Changzhou E-Sound Electronics Co.,Ltd is a medium-sized manufacturing company specializing in electro-acoustic products such as speakers, buzzers, microphones, and receivers. Founded in 1989 and re-established in 1994 with Taiwanese partnership, the company targets business customers in medical equipment, automotive electronics, security, and consumer electronics sectors. The website presents a professional but basic digital presence with product catalogs and company information. Technically, the site uses common JavaScript libraries and Google Analytics but lacks advanced security headers and comprehensive privacy policies. The security posture is moderate with HTTPS implied but missing explicit security headers and incident response information. Overall, the domain WHOIS data is missing, raising concerns about domain registration legitimacy despite the active website. Strategic improvements in security, privacy compliance, and domain registration transparency are recommended.

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. GDPR outside view

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

    • 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics

      What to do: Document all third-party data sharing in your privacy policy

  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

The company operates in the manufacturing sector with a focus on electro-acoustic components. It holds a long-standing market presence with over 30 years of experience. The business model centers on manufacturing and direct sales, targeting industries such as medical, automotive, and consumer electronics. The website supports this with detailed product listings and company history. However, the lack of WHOIS data and privacy policies may impact trust with international partners. The company uses Google Analytics and AddThis for marketing but lacks visible certifications or compliance badges. No social media presence was detected, which could limit digital marketing reach.

Security posture

The website employs HTTPS but lacks critical security headers such as Content-Security-Policy, HSTS, and X-Frame-Options, which are important for mitigating common web attacks. No privacy or cookie policies are present, indicating poor GDPR compliance. No incident response or vulnerability disclosure information is available, limiting transparency in security management. The absence of WHOIS registration data is a significant red flag for domain legitimacy. Overall, the security maturity is moderate but requires enhancements to meet best practices and compliance standards.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Publish clear privacy and cookie policies to improve GDPR and global privacy compliance.
  3. Verify and update domain WHOIS registration to ensure transparency and trust.
  4. Add incident response and vulnerability disclosure information to enhance security posture.
  5. Improve mobile responsiveness and accessibility to enhance user experience and SEO.

Technical notes

Notes

The website uses jQuery and other common JavaScript libraries along with Google Analytics and AddThis for tracking and marketing. The HTML structure is basic but functional with some SEO meta tags present. Mobile optimization is basic with a redirect script for mobile devices. No modern CMS or frameworks were detected. Performance is moderate with image sliders and animations. No advanced accessibility features were identified. The hosting provider and SSL configuration details are not available from the provided data. Overall, the technical implementation is adequate but could benefit from modernization and enhanced security configurations.
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.
