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

K2商务网 is a Chinese B2B platform providing free business registration, product listings, and enterprise directories primarily targeting Chinese manufacturers, suppliers, and buyers. The platform offers a wide range of industry categories including agriculture, manufacturing, logistics, and retail, positioning itself as a comprehensive free B2B marketplace in China. Technically, the website uses standard web technologies including JavaScript and jQuery, with analytics integrations from Baidu and 51.la. The site is moderately optimized for mobile and SEO but lacks advanced security headers and cookie consent mechanisms. Security posture is basic with HTTPS implied but missing explicit security headers. WHOIS data is unavailable, which reduces trust but the presence of ICP license and active content suggests legitimate operation. Overall, the site is functional and business-focused but could improve security and privacy compliance.

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

6 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 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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 operates on a free-to-use B2B model, attracting a broad range of Chinese enterprises across multiple sectors. Its competitive advantage lies in offering free registration and extensive product and supply information, appealing to SMEs and manufacturers seeking exposure. The site maintains a large inventory of categorized listings and active supplier information, indicating a healthy ecosystem. Partnerships with related industry sites are evident through friendly links. However, lack of transparent company contact details and WHOIS data may impact credibility for international users. The business appears medium-sized with a focus on the Chinese domestic market.

Security posture

The website demonstrates a basic security posture with HTTPS usage but lacks critical security headers such as Content-Security-Policy, X-Frame-Options, and HSTS. No explicit privacy or incident response policies are found, and cookie consent mechanisms are absent, indicating potential compliance gaps with GDPR and other privacy regulations. The use of multiple third-party tracking scripts increases the attack surface and privacy risks. No vulnerabilities or malware indicators were detected in the HTML content. Overall, security maturity is low to moderate, with room for significant improvements in headers, privacy, and incident response readiness.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Add a clear cookie consent banner and cookie policy to comply with privacy regulations.
  3. Publish detailed privacy and incident response policies with contact channels for security issues.
  4. Enhance transparency by providing verified company contact emails and phone numbers.
  5. Regularly audit and minimize third-party scripts to reduce privacy and security risks.

Technical notes

Notes

The website uses traditional web technologies with JavaScript and jQuery, supported by Baidu and 51.la analytics. The HTML is well-structured with meta tags for SEO and mobile redirection. Performance is moderate with some lazy loading of images. Mobile optimization is basic but functional. No modern frameworks or CMS are explicitly detected. The site lacks advanced accessibility features and security configurations. Hosting provider details are not discernible from the HTML. Overall, the technical infrastructure is stable but could benefit from modernization and enhanced security practices.
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.
