Risk levelMedium

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

深圳天泷环保科技有限公司 operates as a manufacturer and seller of kitchen and industrial oil smoke purification equipment, including UV light decomposition devices and online monitoring systems. The company targets the Chinese market, serving restaurants, industrial clients, and agents with a medium-sized business model. Their website demonstrates a professional presence with detailed product information, client case studies, and partner logos, indicating a solid market position. Technically, the site uses common JavaScript libraries and frameworks to enhance user experience and is mobile-optimized, though performance is moderate. Security posture is average, with HTTPS implied but lacking explicit security headers and privacy policies. The absence of WHOIS registration data is a significant concern, impacting trust and legitimacy. Overall, the site is safe, business-focused, and functional but requires improvements in compliance and security 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

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 leverages a manufacturing and sales business model focused on environmental protection equipment for commercial kitchens and industrial applications. Their market positioning is supported by partnerships with well-known brands and a network of service points across China. The business model includes direct sales, customized solutions, and agent recruitment. The website content and external links suggest a growing ecosystem with related brands and service providers. However, the lack of public WHOIS data and privacy policies may hinder trust among potential partners and customers. The company appears to be medium-sized with a focus on innovation in IoT-enabled purification devices and after-sales service.

Security posture

The website demonstrates basic security hygiene with HTTPS usage but lacks critical security headers such as Content Security Policy, HSTS, and X-Frame-Options. No incident response or vulnerability disclosure information is provided, and privacy compliance is weak due to missing privacy and cookie policies. Forms are present and use POST methods but lack visible CSRF protections. The use of third-party scripts from Baidu introduces moderate tracking and potential privacy concerns. Overall, the security maturity is moderate but requires enhancements to meet best practices and regulatory compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  3. Publish incident response and vulnerability disclosure policies to demonstrate security readiness.
  4. Verify and publish WHOIS registration data to improve domain legitimacy and trustworthiness.
  5. Conduct regular security audits of third-party scripts and ensure secure form handling with CSRF tokens.

Technical notes

Notes

The website uses a combination of jQuery, Bootstrap, Flexslider, Owl Carousel, Slicknav, and Lightcase libraries to deliver a responsive and interactive user experience. The HTML structure is valid and SEO-friendly with appropriate meta tags and keywords. Mobile optimization is good, and navigation is clear. However, performance is moderate, possibly due to multiple JavaScript dependencies and image sizes. No CMS is detected, suggesting a custom or static site. Hosting provider details are not available. Technical debt appears low but could benefit from modern security and privacy enhancements.
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.
