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

建材网 is a large-scale Chinese building materials industry portal offering comprehensive services including pricing information, market analysis, product supply, procurement, brand promotion, and franchise agency services. The website targets building materials manufacturers, suppliers, agents, and buyers primarily within China. Technically, the site uses jQuery, Baidu Analytics, and supports mobile responsiveness with a dedicated mobile site. Security posture is moderate with HTTPS usage but lacks visible security headers and explicit privacy or cookie policies. WHOIS data is unavailable, which slightly impacts trust but the active and content-rich site suggests legitimacy. Overall, the site is professionally designed and well-structured, serving as a key industry resource.

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

9 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 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';…

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 website holds a strong market position as a leading building materials industry portal in China, with over 1.2 million registered members and extensive industry content. Its business model revolves around information dissemination, product and procurement listings, brand advertising, and franchise services. The site integrates with partner domains such as 59137.com for franchise and agent services. Revenue likely derives from advertising, premium memberships, and service offerings like website construction and targeted marketing. The extensive brand and partner network indicates a mature ecosystem supporting growth and industry influence.

Security posture

The website employs HTTPS, indicating basic encryption for data in transit. However, no security headers (e.g., CSP, HSTS) were detected in the provided data, which could expose the site to certain web-based attacks. No explicit privacy, security, or incident response policies are published, which may affect compliance with regulations like GDPR or NIS2. The use of outdated jQuery 1.8.0 could pose vulnerabilities if not patched. No exposed sensitive data or obvious vulnerabilities were found in the HTML content. Overall, security posture is moderate but could be improved with enhanced headers, updated libraries, and published policies.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish comprehensive privacy and cookie policies to improve compliance and user trust.
  3. Update JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  4. Establish and publish incident response and vulnerability disclosure policies to enhance security transparency.
  5. Conduct regular security audits and penetration testing to identify and remediate potential vulnerabilities.

Technical notes

Notes

The website uses a traditional web stack with jQuery 1.8.0 and Baidu Analytics for tracking. It supports mobile devices via a dedicated mobile site and uses Layer UI components. The site is moderately performant with good SEO meta tags and structured data in JSON-LD format. However, the use of older JavaScript libraries and lack of modern frameworks or CMS indicates potential technical debt. Accessibility features are basic, and there is room for improvement in performance optimization and security hardening. Hosting provider details are not evident from the data.
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.
