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

The website www.zhaodanci.com is an educational platform providing a comprehensive English dictionary and vocabulary resources primarily targeting Chinese-speaking users. It offers various specialized dictionaries including medical, chemical, and university-level English vocabulary, along with grammar and example sentences. The site is positioned as a niche educational resource with a free access business model, focusing on language learning and reference. Technically, the site uses standard web technologies including HTML5, CSS, JavaScript, and jQuery 1.10.2, with a responsive design suitable for both desktop and mobile users. SEO practices are adequately implemented with meta tags and canonical URLs. Security posture is moderate; HTTPS is implied but no advanced security headers or policies are detected. The site lacks privacy, cookie, and terms of service policies, and does not provide contact information or incident response channels, which are notable gaps. The absence of WHOIS data for the domain is suspicious and reduces trustworthiness, although the site content appears legitimate and safe for general audiences. Overall, the site is functional and useful but would benefit from improved security and 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

7 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 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

    • 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

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 serves a specialized market segment of Chinese users seeking English language learning tools and dictionary references. Its competitive advantage lies in the breadth of vocabulary and specialized dictionaries offered freely online. The business model appears to be content-driven with possible monetization through advertising or partnerships, though no explicit revenue streams are visible. The site links to several educational and related resource domains, indicating a partnership ecosystem focused on education. Growth indicators are not evident from the data, and the lack of company or registrant information limits deeper business insights. The platform is small in scale and focused on content delivery rather than commercial transactions.

Security posture

The website demonstrates a basic security posture with HTTPS usage but lacks critical security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options. No privacy or cookie policies are present, indicating non-compliance with GDPR and other privacy regulations. The absence of contact information for security incidents or data protection officers further weakens the security culture. The use of an outdated jQuery version (1.10.2) may expose the site to known vulnerabilities. No visible vulnerabilities or exposed sensitive data were detected, but the lack of security best practices and policies represents a medium risk. Incident response readiness appears minimal or non-existent.

Recommendations

  1. Implement comprehensive privacy and cookie policies to comply with GDPR and enhance user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve security posture.
  3. Upgrade JavaScript libraries, especially jQuery, to the latest secure versions to mitigate vulnerabilities.
  4. Provide clear contact information including security incident response contacts and data protection officer details.
  5. Conduct a WHOIS domain registration review and ensure domain registration information is accurate and publicly available to improve legitimacy and trust.

Technical notes

Notes

The website uses a simple technology stack with HTML5, CSS, and JavaScript, including jQuery 1.10.2. The site is mobile responsive with a toggle menu for smaller screens, indicating attention to mobile usability. SEO is supported by meta tags and canonical URLs. Performance is moderate with no explicit indicators of slow loading but no advanced optimization detected. No CMS or hosting provider information is discernible from the content. The site lacks modern security features and could benefit from technical modernization including updated libraries and enhanced 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.
