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

The website www.yanedu.com serves as a comprehensive information portal for in-service graduate education in China, focusing on various programs such as in-service master's, doctoral, MBA, EMBA, and advanced training courses. It provides detailed admission guides, exam information, and online registration forms targeting working professionals seeking to advance their education while employed. The platform aggregates information from multiple reputable Chinese universities and research institutes, positioning itself as a key resource in the education sector for adult learners. Technically, the site employs common web technologies including jQuery, Microsoft Clarity, Baidu Analytics, and 51.la analytics, indicating a moderate level of digital maturity. The presence of multiple tracking and chat tools suggests an emphasis on user engagement and data collection. Security posture is moderate; while HTTPS is used, no explicit security headers were detected, and client-side form validation is present but server-side protections are unknown. The absence of privacy and cookie policies is a compliance gap. WHOIS data is unavailable, raising concerns about domain registration legitimacy, though the website content and structure appear professional and trustworthy. Overall, the site is functional and content-rich but would benefit from enhanced security and privacy compliance measures.

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. 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 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';…

  4. 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 operates in the education sector, specifically targeting adult learners interested in continuing education and professional development through graduate programs. Its business model revolves around providing detailed program information, facilitating online registrations, and acting as a bridge between prospective students and educational institutions. The site features partnerships with multiple well-known Chinese universities, enhancing its credibility and reach. The target audience includes working professionals across various regions in China, as evidenced by regional links and course offerings. The site’s extensive content and structured navigation indicate a mature content strategy aimed at maximizing user engagement and conversion. However, the lack of transparent privacy policies and unclear domain registration status could impact user trust and regulatory compliance.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is enforced, ensuring encrypted communications. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks like clickjacking and cross-site scripting. Client-side form validation is implemented, but no evidence of server-side validation or anti-CSRF measures is present. The use of multiple third-party analytics and chat services introduces potential privacy and security risks if not properly managed. The missing privacy and cookie policies further highlight compliance deficiencies. The unknown domain registration status adds an element of risk regarding the legitimacy and ownership of the domain. To improve, the site should implement comprehensive security headers, conduct regular vulnerability assessments, and establish clear privacy and incident response policies.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to comply with data protection regulations.
  2. Add essential HTTP security headers such as CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance security.
  3. Verify domain registration details and ensure WHOIS information is accurate and publicly available to improve trustworthiness.
  4. Conduct server-side validation and implement anti-CSRF tokens on all forms to prevent injection and forgery attacks.
  5. Regularly update all third-party libraries and monitor analytics and chat tools for privacy compliance and security risks.

Technical notes

Notes

The website is built using traditional web technologies, primarily jQuery 1.10.1, with integration of analytics tools like Microsoft Clarity, Baidu Analytics, and 51.la. It uses asynchronous loading for scripts to improve performance. The site includes responsive design elements for mobile optimization and features multiple interactive components such as image sliders and dynamic content sections. However, the use of an older jQuery version may pose security risks. The hosting provider is not explicitly identified, and no CMS is detected. Performance is moderate, with room for improvement in accessibility and SEO through enhanced semantic markup and ARIA attributes. The site structure is clear, supporting good user navigation and content discoverability. Overall, the technical infrastructure supports the business needs but requires modernization and security hardening.
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.
