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

山东云唐智能科技有限公司 is a specialized manufacturer and supplier of plant physiology and agricultural scientific instruments, including chlorophyll meters, photosynthesis measurement devices, leaf area meters, canopy analyzers, and fruit and vegetable respiration meters. The company targets agricultural research institutions, food and drug supervision agencies, and third-party testing organizations across China. Their product portfolio is comprehensive, supported by years of R&D experience, and distributed nationwide. Technically, the website employs standard web technologies such as HTML5, CSS3, JavaScript with jQuery, and integrates Baidu and CNZZ analytics, indicating a focus on the Chinese market. The site is moderately optimized for performance and mobile use but lacks advanced accessibility features. Security posture is moderate with no visible critical vulnerabilities but lacks security headers and explicit privacy or cookie policies, which are compliance gaps. WHOIS data is unavailable, which reduces domain trustworthiness, but the website content and business information appear professional and consistent. Overall, the site is safe for general audiences and provides clear contact information and product details.

NIS2 Art. 21(2)

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

8 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"

    • 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

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 holds a solid position as a manufacturer in the agricultural scientific instrument sector, offering a wide range of specialized devices. Their business model focuses on manufacturing and direct sales with a strong emphasis on research and development. The presence of multiple partner domains and customer case studies indicates an established ecosystem and market presence. The company leverages online marketing and analytics tools to reach its target audience, primarily in China. However, the absence of privacy and cookie policies may pose compliance risks in international markets. The company’s growth potential is supported by its comprehensive product line and collaboration with academic and research institutions.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS usage is implied but not explicitly confirmed. No security headers such as Content Security Policy, HSTS, or X-Frame-Options were detected, which are recommended to mitigate common web vulnerabilities. No exposed sensitive data or vulnerable libraries were found in the HTML content. The site lacks a published security policy or incident response contact information, which limits transparency and preparedness. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the security posture is adequate for informational purposes but requires enhancements to meet best practices and regulatory requirements.

Recommendations

  1. Implement and enforce HTTPS with a valid SSL certificate and verify its configuration.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and other regulations.
  3. Deploy security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  4. Publish a security policy and provide incident response contact information to improve transparency and trust.
  5. Enhance mobile responsiveness and accessibility features to improve user experience and compliance.

  4. No security headers detected in provided data; security posture can be improved.
  5. WHOIS data unavailable, limiting domain trust verification.

Technical notes

Notes

The website uses a traditional web stack with HTML5, CSS3, and JavaScript libraries including jQuery and AOS for animations. It integrates Baidu and CNZZ analytics for user tracking and marketing insights. The site structure is clear with good navigation and content organization. Performance is moderate with room for improvement in mobile optimization and accessibility. No CMS or hosting provider information was detected. The site uses custom scripts for UI interactions and navigation. There is no evidence of modern frameworks like React or Angular. Technical debt appears low but modernization opportunities exist to improve performance and security.
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.
