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

搜了网 (51sole.com) is a leading Chinese B2B vertical commercial search engine and systematic online marketing platform. It provides enterprise users with market trends, procurement, wholesale, product information, and online promotion services, positioning itself as a preferred industry portal for e-commerce and online marketing. The platform offers a wide range of services including product search, company listings, exhibition information, and marketing tools such as short video SEO and bidding services. Technically, the website uses established JavaScript libraries like jQuery and Swiper, supports mobile optimization with a dedicated mobile site, and integrates Baidu analytics for user tracking. Security-wise, the site uses HTTPS but lacks advanced security headers and cookie consent mechanisms, which are recommended for improved compliance and protection. The WHOIS data is unavailable, which slightly reduces transparency, but the presence of official certifications and business information supports legitimacy. Overall, the website is professionally designed, content-rich, and serves a large B2B audience in China.

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. 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 business operates in the manufacturing and retail sectors, focusing on B2B e-commerce and online marketing services. It targets Chinese enterprises seeking procurement and promotional solutions. The platform's competitive advantage lies in its comprehensive industry coverage, extensive product and company listings, and integration of modern marketing tools such as short video promotion and multi-platform bidding. Revenue streams likely include advertising, premium memberships, and value-added marketing services. The company maintains a broad partnership ecosystem with multiple industry-related websites and platforms, enhancing its market reach and service offerings. Growth indicators include active new company listings and continuous promotional campaigns. Strategic observations suggest focusing on enhancing security and privacy compliance to strengthen trust and regulatory adherence.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible exposure of sensitive data. However, it lacks critical security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate common web attacks. There is no visible incident response or vulnerability disclosure policy, and no cookie consent mechanism despite the use of tracking scripts, indicating compliance gaps with privacy regulations like GDPR. The absence of WHOIS registrant data reduces transparency and trustworthiness. Overall, while no immediate vulnerabilities are apparent, improvements in security headers, privacy compliance, and public security policies are recommended to enhance the security posture and reduce business risk.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Deploy a cookie consent mechanism to comply with privacy regulations and inform users about tracking practices.
  3. Regularly update JavaScript libraries and dependencies to the latest secure versions to avoid vulnerabilities.
  4. Publish clear security and incident response policies on the website to improve transparency and preparedness.
  5. Monitor WHOIS data and consider domain privacy protection strategies aligned with business transparency requirements.

Technical notes

Notes

The website employs a traditional web technology stack with jQuery 1.9.1 and Swiper 2.7.6 for UI components, supported by custom JavaScript and CSS. It uses Baidu Analytics for user tracking and has a responsive design with a dedicated mobile site. Performance is moderate, with room for optimization in loading speed and accessibility features. The absence of a detected CMS suggests a custom or proprietary platform. Hosting provider details are not disclosed. Technical debt is indicated by the use of older JavaScript libraries. Modernization opportunities include upgrading libraries, implementing progressive web app features, and enhancing accessibility compliance to improve user experience and operational resilience.
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.
