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

Kaoyantexun.com is the official website of Chengdu Wanxue Haiwen Education Technology Co., Ltd., a recognized Chinese education company specializing in graduate exam preparation and training services. The site offers a broad range of educational products including full-time and part-time graduate exam coaching, MBA training, online courses, and consulting services. It targets students preparing for graduate exams and working professionals seeking further education. The company holds a solid market position in China’s education sector with a medium-sized operational scale and a founding date in 2018. Technically, the website employs a modern tech stack including Bootstrap, jQuery, Swiper.js, and integrates multiple third-party services such as Baidu Analytics and 53KF online chat for user engagement and tracking. The site is mobile-optimized and structured for good SEO, though accessibility features are basic. Performance is moderate with room for optimization. From a security perspective, the site uses HTTPS and has domain transfer protections but lacks explicit HTTP security headers and DNSSEC. No privacy or cookie policies are present, indicating compliance gaps with GDPR and related regulations. The WHOIS data is consistent and trustworthy, with no privacy protection, supporting legitimacy. User tracking is moderate due to analytics and marketing scripts. Overall, the website is professional and content-rich, serving its educational purpose well. However, it should improve privacy compliance, security headers, and transparency to enhance trust and regulatory adherence.

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 company operates in the education sector, focusing on graduate exam preparation and related training services. It leverages a hybrid business model combining online and offline offerings, including courses, consulting, and study materials. The presence of multiple regional subdomains indicates a broad geographic reach within China. The company benefits from media coverage and official recognitions, enhancing its brand credibility. Its partnership with service providers like 53KF for customer engagement and Baidu for analytics reflects a mature digital marketing approach. Growth indicators include active content updates and diversified service offerings. The company’s operations appear well-structured with a clear target audience of graduate students and working professionals.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and domain transfer protection. However, it lacks critical HTTP security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options, which are important for mitigating common web attacks. DNSSEC is not enabled, which could improve DNS security. No explicit security or incident response policies are published, and no dedicated security contact channels are visible. The use of multiple third-party scripts increases the attack surface and requires careful management. Overall, while basic security measures are in place, enhancements are needed to meet higher security standards and compliance requirements.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Enable DNSSEC to secure DNS queries and prevent spoofing.
  3. Publish clear privacy and cookie policies with user consent mechanisms to comply with GDPR and other privacy regulations.
  4. Establish and publicize an incident response policy and security contact channels to improve transparency and readiness.
  5. Conduct regular security audits of third-party scripts and minimize unnecessary external dependencies to reduce risk.

Technical notes

Notes

The website uses a combination of Bootstrap for responsive design, jQuery for DOM manipulation, and Swiper.js for interactive sliders. It integrates Baidu Analytics for traffic analysis and 53KF for live chat support, indicating a focus on user engagement and data-driven marketing. The site is mobile-optimized with adaptive scripts and responsive CSS. Performance is moderate, with potential improvements in loading speed and accessibility. The absence of a CMS indication suggests a custom or proprietary platform. The domain is registered with Bizcn.com, Inc., a known registrar, and the site uses HTTPS consistently. Technical debt appears low but security and privacy implementations require modernization.
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.
