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

维库电子市场网 (www.dzsc.com) is a well-established Chinese electronic components procurement platform with over 16 years of industry presence. It serves a large user base including electronic engineers and manufacturing factories, providing extensive product listings, technical datasheets, and e-commerce services. The platform targets electronic product manufacturers, sellers, and consumers, positioning itself as a leading marketplace and information hub in the electronics sector. Technically, the website employs standard web technologies including jQuery and Baidu Analytics, with a mobile-optimized version accessible via redirection. Security posture is strong with HTTPS enforcement and basic security headers, though privacy compliance could be improved with explicit cookie consent and detailed privacy policies. No WAF or blocking mechanisms were detected, allowing full content access. Overall, the site demonstrates a mature digital infrastructure and professional business model, though it lacks some modern privacy and security disclosures.

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 business operates primarily in the technology and e-commerce sectors, focusing on electronic components procurement and information services. It leverages a large registered user base and offers multiple services including product listings, procurement posting, certification services, and free sample distribution. The platform integrates several subdomains for specialized services such as video content, job recruitment, and datasheet repositories, indicating a diversified ecosystem. Market positioning is strong domestically with a recognized brand and extensive product catalog. Revenue streams likely include advertising, membership services, and transaction facilitation. The company appears to maintain partnerships within its domain ecosystem but does not publicly disclose parent or subsidiary companies. Growth indicators include active procurement listings and a broad product classification system.

Security posture

The website maintains a good security posture with HTTPS enabled and several security headers present. There is no evidence of exposed sensitive data or vulnerable libraries in the provided content. However, the absence of explicit privacy policies, cookie consent mechanisms, and incident response contacts indicates gaps in compliance and transparency. The use of Baidu Analytics introduces moderate user tracking, which should be disclosed more clearly to comply with privacy regulations. No vulnerability disclosure or security.txt files were found, limiting external security engagement. Overall, the security maturity is moderate to good but can be enhanced by adopting comprehensive privacy and incident response frameworks.

Recommendations

  1. Implement a clear and accessible cookie consent banner to comply with GDPR and other privacy regulations.
  2. Publish detailed privacy and security policies including data protection and incident response procedures.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve security transparency.
  4. Enhance accessibility features to meet modern standards and improve user experience for all users.
  5. Regularly update and audit third-party libraries and analytics tools to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a traditional web stack with jQuery 1.11.1 and Baidu Analytics for tracking. It employs standard HTML5 and CSS3 with some JavaScript for UI interactions and search autocomplete. Mobile optimization is handled via redirection to a dedicated mobile subdomain. Performance appears moderate with multiple external resources loaded from subdomains. The site lacks modern JavaScript frameworks or CMS indicators, suggesting a custom or legacy platform. SEO is supported by meta tags and structured navigation. Technical debt may exist due to older library versions and limited accessibility features. Opportunities exist to modernize the tech stack, improve performance, and enhance compliance with privacy and security standards.
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.
