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

The website www.gk100.com is an educational platform focused on providing comprehensive information and services related to the Chinese college entrance examination (Gaokao). Operated by 成都圆梦时刻科技有限公司, it offers university rankings, major rankings, admission scores, volunteer application guidance, exam question banks, and employment reports. The site targets high school seniors and Gaokao candidates, positioning itself as a specialized resource in the education sector within China. The content is rich, well-structured, and professionally presented, with good mobile optimization and clear navigation. Technically, the site employs a modern tech stack including jQuery, Baidu Analytics, Baidu and ByteDance push services, and a third-party chat agent. It uses HTTPS exclusively, ensuring encrypted communication. However, it lacks explicit security headers and privacy/cookie policies, which are important for compliance and security hardening. The WHOIS data is unavailable or unregistered, which raises concerns about domain legitimacy despite the professional appearance and trust indicators on the site. Security posture is moderate with no visible vulnerabilities or exposed sensitive data, but improvements are needed in security headers and privacy compliance. The absence of contact emails and phone numbers reduces direct communication transparency. Overall, the site is safe, trustworthy, and content-appropriate for its audience, but domain registration opacity and privacy policy gaps present moderate risks.

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

6 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 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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 education sector, focusing on Gaokao-related content and services. Its market position is that of a specialized information platform catering to Chinese high school students preparing for university entrance. The business model revolves around content provision, likely monetized through advertising and partnerships. The presence of multiple partner domains and certifications suggests a well-established ecosystem. The company is medium-sized, with consistent branding and professional content quality. Growth indicators include frequent content updates and diversified service offerings such as employment reports and volunteer application guidance. The lack of explicit company contact details and WHOIS transparency may impact credibility but does not detract from its operational presence in the education market.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced, ensuring secure data transmission. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No privacy or cookie policies are present, indicating compliance gaps with GDPR and similar regulations. Incident response and vulnerability disclosure information are absent, limiting transparency in security management. Third-party scripts are used extensively, which could introduce risks if not regularly audited. No exposed credentials or sensitive data were detected. Overall, the site is secure for general use but requires enhancements in policy transparency and security controls to improve resilience and compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to ensure regulatory compliance.
  2. Add essential security headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options) to strengthen web security.
  3. Publish incident response and vulnerability disclosure information to improve transparency and trust.
  4. Provide clear company contact information including verified emails and phone numbers to enhance communication.
  5. Regularly audit and update third-party scripts to mitigate potential security vulnerabilities.

Technical notes

Notes

The website uses a combination of jQuery and several third-party JavaScript libraries for analytics, push notifications, and chat functionality. The HTML is well-structured with appropriate meta tags for SEO and mobile responsiveness. The site loads resources from multiple subdomains under gk100.com and trusted external domains. Performance is moderate with no obvious blocking or errors. Mobile optimization is good, supported by an alternate mobile site link. Accessibility features are basic but could be improved. No CMS was detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the content. Overall, the technical implementation supports a stable and user-friendly experience but could benefit from enhanced accessibility and security configurations.
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.
