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

山东国康电子科技有限公司 operates a website focused on manufacturing and selling medical devices, particularly auditory integration training instruments and traditional Chinese medicine diagnostic equipment. The company targets healthcare providers, rehabilitation centers, and traditional medicine practitioners, positioning itself as a specialized manufacturer with proprietary technology and a comprehensive service model including R&D, production, sales, installation, and after-sales support. The website content is professionally presented in Chinese, with clear product categories, customer cases, and contact information, indicating a small but focused business entity primarily serving the Chinese market and exporting to Southeast Asia. Technically, the website uses standard web technologies including jQuery and Baidu Analytics, with basic mobile optimization and SEO practices. The site is accessible without any WAF or security challenges detected. However, the absence of explicit privacy, cookie, and terms of service policies indicates gaps in compliance and user transparency. The WHOIS data for the domain is missing, which raises concerns about domain registration legitimacy and trustworthiness. From a security perspective, the site enforces HTTPS and does not expose sensitive data or use vulnerable libraries, but lacks security headers and formal security policies. The tracking via Baidu Analytics suggests moderate user tracking without clear privacy compliance. Overall, the security posture is moderate but could be improved with better policy disclosures and technical hardening. The overall risk assessment highlights the need for domain registration verification and enhanced privacy compliance. Strategic recommendations include implementing comprehensive privacy and cookie policies, adding security headers, improving mobile responsiveness, and establishing incident response and vulnerability disclosure mechanisms to strengthen trust and security culture.

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

7 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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 operates in the healthcare and technology sectors, focusing on niche medical devices for auditory integration and traditional Chinese medicine diagnostics. Its business model integrates product manufacturing with direct sales and after-sales services, targeting medical institutions and rehabilitation centers. The presence of customer case studies and export activities indicates active market engagement and growth potential. The website's external links suggest partnerships within related medical and testing equipment industries. However, the lack of WHOIS transparency and privacy policies may affect credibility with international partners and customers. The company appears to be a small-sized enterprise with a consistent brand presence in its domain.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no obvious exposure of sensitive data. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No incident response or vulnerability disclosure information is provided, limiting preparedness for security incidents. Privacy compliance is weak due to missing privacy and cookie policies, which may expose the company to regulatory risks, especially under GDPR or similar frameworks. The use of Baidu Analytics indicates user tracking without clear consent mechanisms. Overall, the security posture is functional but requires improvements in policy transparency, technical defenses, and compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear user consent mechanisms.
  2. Add security headers including Content Security Policy, HSTS, and X-Frame-Options to enhance web security.
  3. Verify and update domain WHOIS registration to ensure transparency and trustworthiness.
  4. Establish incident response and vulnerability disclosure procedures accessible to users.
  5. Improve mobile optimization and accessibility to enhance user experience across devices.

Technical notes

Notes

The website is built using classic web technologies including jQuery and jBox for UI components, with Baidu Analytics for user tracking. The site supports mobile devices via redirection but has only basic mobile optimization. SEO is basic with meta tags present but no advanced structured data or Open Graph tags detected. The site lacks modern frameworks or CMS indications, suggesting a custom or legacy build. Performance is moderate with no explicit speed optimizations noted. The absence of security headers and privacy policies indicates technical debt in security and compliance areas. Overall, the infrastructure is stable but would benefit from modernization and enhanced security controls.
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.
