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

The website www.linxuan123.com is a specialized educational platform operated under the Huatu Education brand, focusing on providing comprehensive information and preparatory resources for Chinese government civil servant selection exams, specifically the '遴选' exams. It offers exam announcements, position downloads, registration portals, study materials, and paid courses. The site is well-structured, content-rich, and targets exam candidates seeking authoritative guidance and training. Technically, the site uses common web technologies such as jQuery and Swiper.js, integrates Baidu analytics and a third-party chat support system, and is mobile-optimized. However, it lacks visible privacy and cookie policies, which is a compliance gap. Security-wise, HTTPS is used but no explicit security headers were detected, and the WHOIS data for the domain is missing, which is unusual and warrants caution. Overall, the site appears legitimate and professional but could improve its compliance and security posture.

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

8 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 holds a strong position in the niche market of Chinese civil servant exam preparation, leveraging the established Huatu Education brand. Its business model combines free informational content with monetized online courses and study materials. The target audience is primarily Chinese government exam candidates. The site maintains partnerships with related Huatu domains and uses multiple marketing and analytics tools to engage users. Growth indicators include frequent content updates and active course offerings. The lack of direct contact emails or phone numbers on the site may limit direct customer engagement but is supplemented by online chat support. The missing WHOIS data is a minor risk factor but does not currently impact operational credibility.

Security posture

The website demonstrates a moderate security posture. HTTPS is enforced, which protects data in transit. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. The use of third-party scripts introduces potential risks if not properly managed. No exposed sensitive data or vulnerable libraries were detected in the provided content. The site lacks visible privacy and cookie policies, indicating compliance gaps with data protection regulations such as GDPR. Incident response and security policy information are not publicly available, which limits transparency. Overall, while no critical vulnerabilities are evident, improvements in security headers and compliance documentation are recommended.

Recommendations

  1. Implement comprehensive privacy and cookie policies to enhance compliance and user trust.
  2. Add and configure HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  3. Regularly update and audit third-party libraries and scripts to mitigate vulnerabilities.
  4. Publish security policy and incident response contact information to improve transparency.
  5. Consider verifying and updating WHOIS registration information to ensure domain legitimacy.

Technical notes

Notes

The website uses a traditional web stack with jQuery 2.1.4 and Swiper.js for UI components and interactivity. It integrates Baidu Analytics and CNZZ for user tracking and uses Sobot for live chat support. The site is mobile-responsive and includes HTML5 video content. The meta tags and SEO elements are well implemented, supporting good search engine visibility. However, the site does not appear to use a modern CMS or advanced frameworks. Performance is moderate, with potential improvements in loading speed and accessibility. The absence of security headers and privacy policies indicates technical debt in security and compliance areas. Hosting provider details are not discernible from the content. Overall, the technical infrastructure is functional but could benefit from modernization and enhanced security controls.
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.
