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

查校网 is a Chinese educational directory website specializing in providing comprehensive listings and rankings of various schools including kindergartens, primary schools, secondary schools, vocational schools, and universities across China. The platform targets parents and students seeking detailed school information such as addresses, admission contacts, and alumni reviews. It holds a moderate market position as a specialized school query and ranking service with a large database of nearly 500,000 schools. Technically, the website employs standard web technologies including jQuery and JavaScript, supports mobile redirection, and uses HTTPS for secure connections. However, it lacks advanced security headers and privacy compliance mechanisms such as cookie consent banners or detailed privacy policies. The WHOIS data for the domain is unavailable, which raises some concerns about domain legitimacy, though the presence of a valid ICP license indicates regulatory compliance within China. Overall, the site offers good content quality and user experience but has room for improvement in security and privacy compliance.

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 business model of 查校网 revolves around providing a centralized platform for school information and rankings, serving a niche audience of parents and students in China. Its competitive advantage lies in the extensive database and categorized school listings by region and type. Revenue streams are not explicitly visible but may include advertising or partnerships with educational institutions. The website maintains a consistent brand presence with clear navigation and relevant content. The lack of direct contact phone numbers and limited transparency in domain registration may impact trustworthiness. The platform appears to be a medium-sized operation focused on education sector services within China, with no evident parent or subsidiary companies. Strategic growth could involve enhancing privacy compliance and expanding contact channels.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communication. However, it lacks important security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are critical for mitigating common web vulnerabilities. No forms or inputs on the homepage reduce immediate risk of injection attacks, but the absence of incident response or vulnerability disclosure information indicates limited preparedness for security incidents. The use of third-party scripts like Baidu analytics and push services introduces potential supply chain risks if not regularly audited. Privacy compliance is weak, with no cookie consent or privacy policy, which could lead to regulatory issues. Overall, the security maturity is moderate but requires enhancements to meet best practices and compliance standards.

Recommendations

  1. Implement comprehensive privacy and cookie policies with explicit user consent mechanisms to improve compliance.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against attacks.
  3. Establish and publish an incident response plan and vulnerability disclosure policy to enhance security transparency and readiness.
  4. Introduce clear and verified contact phone numbers and expand contact channels to improve business credibility and user trust.
  5. Regularly audit and update third-party scripts and dependencies to minimize supply chain vulnerabilities.

Technical notes

Notes

The website uses a traditional web stack with jQuery and JavaScript, serving content optimized for both desktop and mobile platforms. It employs HTTPS, ensuring secure data transmission. The site structure is well-organized with clear navigation and categorized content, supporting good SEO practices. However, the absence of a detected CMS suggests a custom or lightweight platform, which may limit scalability or ease of updates. Performance is moderate with no explicit indicators of advanced optimization or CDN usage. Accessibility features are basic, and there is room for improvement in compliance with modern web standards. The technical debt appears manageable but addressing security headers and privacy compliance will reduce risks and improve overall digital maturity.
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.
