Risk levelHigh

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

江苏国消设备安装有限公司 is a specialized company focused on cleanroom and purification engineering, including turnkey projects and fire protection construction primarily serving industries such as biomedicine, electronics, food, and cosmetics in China. The company has a solid regional presence with 15 years of experience and over 200 successful projects, positioning itself as a trusted local service provider. The website reflects a professional business model with clear service offerings and client engagement channels. Technically, the site uses modern JavaScript libraries like jQuery and Swiper, and is built on the FeiChi CMS platform, showing moderate digital maturity with responsive design and good SEO practices. Security posture is moderate with HTTPS assumed but lacking explicit security headers and policies, and privacy compliance is weak due to missing privacy and cookie policies. Overall, the site is trustworthy but could improve in security and compliance transparency.

NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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';…

  4. 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 operates in the manufacturing sector, providing comprehensive cleanroom design, installation, and maintenance services. Its business model revolves around project contracting and equipment sales, targeting industrial clients requiring GMP-level clean environments. The company leverages partnerships with regional firms and maintains a portfolio of certifications and case studies to build credibility. Growth indicators include a steady client base and repeat business. The website content and navigation support clear communication of services and expertise, though privacy and security policy disclosures are lacking. The partnership ecosystem is regional and focused on complementary service providers.

Security posture

The website demonstrates a basic security maturity level with HTTPS usage but lacks critical security headers such as CSP, HSTS, and X-Frame-Options. No incident response or vulnerability disclosure information is provided, which limits transparency for security issues. Forms use POST methods but lack visible anti-CSRF tokens. No privacy or cookie policies are present, indicating compliance gaps with GDPR and related regulations. No analytics or tracking scripts beyond Baidu link submission are detected, reducing privacy risks but also limiting user behavior insights. Overall, the security posture is functional but requires enhancements to meet best practices and regulatory compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear user consent mechanisms to improve compliance.
  2. Add HTTP security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-XSS-Protection to enhance security posture.
  3. Establish a vulnerability disclosure policy and provide security contact information to improve incident response readiness.
  4. Incorporate anti-CSRF tokens or other protections in forms to prevent cross-site request forgery attacks.
  5. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities and improve performance.

Technical notes

Notes

The website is built using the FeiChi CMS platform with front-end technologies including jQuery 3.5.1 and Swiper.js for interactive elements. The HTML and CSS are valid and support responsive design, providing a good user experience on mobile devices. Performance is moderate with some lazy loading of images to optimize load times. SEO is supported by meta keywords, descriptions, and structured navigation menus. However, the absence of advanced frameworks or backend technology details limits deeper technical assessment. Hosting provider details are not disclosed. The site could benefit from enhanced accessibility features and performance optimizations.
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.
