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"

    • 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 platform positions itself as a specialized e-commerce service within the foreign trade sector, focusing on real-person supplier and buyer interactions. Its business model revolves around user-generated supply and demand posts and profile showcases, likely monetized through membership or listing fees. The presence of multiple active user profiles from various countries suggests a growing user base. However, the lack of explicit contact details and limited transparency on company founding date or subsidiaries limits deeper business intelligence. The company leverages Baidu Analytics for user tracking and appears to maintain regulatory compliance with Chinese authorities.

Security posture

The website enforces HTTPS, ensuring encrypted communications. However, it lacks critical security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No explicit security or incident response policies are published, and no contact channels for security issues are provided. The absence of cookie consent mechanisms and privacy compliance indicators suggests gaps in regulatory adherence, particularly for GDPR or similar frameworks. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is moderate but could be significantly improved with standard best practices.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common attacks.
  2. Add a cookie consent banner and detailed privacy policy to improve compliance with privacy regulations such as GDPR.
  3. Publish a dedicated security policy and provide incident response contact information to build trust and readiness.
  4. Improve mobile responsiveness and accessibility features to enhance user experience and inclusivity.
  5. Investigate and resolve WHOIS data inconsistencies to improve domain legitimacy and trustworthiness.

Key observations

  1. Website is a Chinese B2B platform connecting foreign trade buyers and suppliers.
  2. Content is primarily in Chinese with an English subdomain available.
  3. No contact emails or phone numbers explicitly provided on main page or footer.
  4. No privacy or cookie consent banners detected despite presence of user agreement.
  5. No security headers detected in HTML content; HTTPS is used.
  6. Website uses Baidu Analytics for tracking.
  7. WHOIS data is missing or domain not found in public WHOIS, which is unusual for an active commercial site.
  8. Site footer includes official ICP and public security registration numbers indicating Chinese regulatory compliance.
Technical notes

Notes

The website uses a traditional tech stack including jQuery 3.2.1 and Baidu Analytics for tracking. The HTML structure is valid and includes appropriate meta tags for SEO. Static assets are served from a dedicated CDN domain (static.52wmb.com), which likely improves loading performance. The site is moderately optimized for mobile devices but lacks advanced accessibility features. No modern JavaScript frameworks or CMS platforms were detected, indicating a possibly custom or legacy implementation. Performance is moderate with room for improvement in responsiveness and accessibility compliance.
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.
