Security score

73/100

Risk levelMedium

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

广东银纳科技有限公司 is a specialized provider of high-end metal 3D printing solutions based in China, focusing on manufacturing and supplying various metal powders including spherical tantalum and tungsten powders, nanopowders, and refractory metal powders. The company also offers 3D printing services and education/training programs, targeting industrial sectors such as medical, military, and manufacturing. The website is professionally designed with good mobile optimization and clear navigation, supporting a moderate level of digital maturity. However, the absence of privacy and cookie policies, as well as missing WHOIS registration data, indicates gaps in compliance and domain legitimacy verification. Security posture is moderate with HTTPS usage but lacks explicit security headers and incident response information. Overall, the site presents a credible business front but requires improvements in privacy compliance and domain registration transparency.

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

4 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 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

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 and technology sectors, providing metal 3D printing powders and related services. Its business model is B2B, serving industrial clients requiring advanced metal powders and 3D printing expertise. The firm has a recognized market position with specialized technology and a comprehensive service offering including powder modification and education. The website links to multiple external domains, mostly industry-related or service providers, indicating a broad partnership ecosystem. Growth potential is supported by the expanding 3D printing market and demand for specialized metal powders. However, the lack of WHOIS data and privacy policies may affect trust and regulatory compliance.

Security posture

The website uses HTTPS and includes third-party analytics and chat services, but lacks visible security headers such as CSP, HSTS, or X-Frame-Options. No forms collecting sensitive data are present, reducing immediate risk exposure. The absence of privacy and cookie policies, incident response contacts, and vulnerability disclosure mechanisms indicates limited security governance and compliance maturity. The missing WHOIS registration data raises concerns about domain legitimacy and potential risks. Overall, the security posture is moderate but requires enhancements in policy transparency and technical security controls.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to improve compliance.
  2. Add security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  3. Publish incident response and vulnerability disclosure information to build trust and readiness.
  4. Verify and update WHOIS domain registration details to ensure legitimacy and transparency.
  5. Enhance accessibility features and SEO optimization to improve user experience and reach.

Technical notes

Notes

The website employs a mix of JavaScript libraries including jQuery, Swiper.js for sliders, LightGallery for image galleries, and Layx for web chat functionality. Analytics are provided by Baidu and hm.webcount.cn. The site is mobile optimized with responsive design and uses multiple CSS stylesheets for layout and media queries. No CMS is detected, suggesting a custom or static site architecture. Performance is moderate with some external dependencies. The absence of security headers and privacy policies indicates technical debt in security and compliance areas. The WHOIS data is missing, which is a technical and administrative risk. Overall, the technical infrastructure supports the business needs but requires modernization and security improvements.
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.
