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

河南铜创有色金属科技有限公司 operates a professional manufacturing website specializing in copper-aluminum composite materials including plates, strips, foils, heat sinks, and related products. The company emphasizes advanced production equipment, R&D capabilities, and serves industries such as energy, telecommunications, and manufacturing. The website is well-structured with detailed product descriptions and multiple trust indicators, targeting industrial clients requiring customized composite materials. Technically, the website uses modern JavaScript libraries such as jQuery, Swiper.js, and WOW.js, and integrates Baidu Analytics for user tracking. The site is mobile-optimized and provides a good user experience. However, there is a lack of explicit privacy and cookie policies, and no visible security headers, which are areas for improvement. From a security perspective, the site uses HTTPS and avoids exposing sensitive data, but lacks comprehensive security policies and incident response contacts. The WHOIS data for the domain is missing, which raises concerns about domain legitimacy and registration transparency. This discrepancy between professional website content and missing domain registration data suggests a need for verification. Overall, the website is functional and professional but would benefit from enhanced privacy compliance, security best practices, and domain registration transparency to improve trustworthiness 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

6 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  3. 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

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 positions itself as a source manufacturer with a medium-sized operation founded in 2017, focusing on copper-aluminum composite materials for various industrial applications including lithium batteries, power fittings, LED base plates, and decorative materials. Their business model centers on manufacturing and direct sales with customization options. The company highlights strong production capabilities, quality assurance, and customer service. The website content and certifications indicate a stable market presence in China’s manufacturing sector, targeting industrial clients and energy-related industries. The extensive product catalog and detailed descriptions suggest a mature product offering with potential for growth in emerging sectors like electric vehicles and telecommunications.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and no visible exposure of sensitive data. However, the absence of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security robustness. There is no published security policy or incident response contact information, which limits transparency and preparedness for security incidents. The use of third-party analytics scripts introduces potential privacy concerns without clear cookie or privacy policies. The missing WHOIS registration data is a critical concern for domain legitimacy and trust. Overall, the security maturity is moderate but requires enhancements in policy transparency, technical controls, and domain registration verification.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to comply with data protection regulations.
  2. Add HTTP security headers including Content Security Policy, HSTS, and X-Frame-Options to strengthen security posture.
  3. Provide clear security incident response contact information and establish a formal security policy.
  4. Verify and update domain WHOIS registration data to ensure transparency and legitimacy.
  5. Conduct regular security audits of third-party scripts and improve accessibility features for broader compliance.

Technical notes

Notes

The website uses a modern front-end technology stack including jQuery, Swiper.js for sliders, and WOW.js for animations, providing a dynamic and responsive user experience. Baidu Analytics is integrated for user behavior tracking. The site is mobile-optimized with responsive design and clear navigation. However, there is no detected CMS or backend technology disclosed. Performance appears moderate with no major issues detected. The lack of security headers and privacy policies indicates technical debt in security and compliance areas. Opportunities exist to enhance technical infrastructure by adopting security best practices and improving privacy compliance mechanisms.
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.
