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

The website www.zhzidian.com serves as an authoritative online Chinese dictionary platform providing extensive language resources including character meanings, pinyin, stroke order, radicals, and classical dictionary references. It targets Chinese language learners and users seeking comprehensive dictionary services. The site offers a broad range of language tools such as idioms, synonyms, antonyms, and English-Chinese dictionary features, positioning itself as a valuable educational resource in the Chinese language education sector. Technically, the site is built with standard web technologies including HTML, CSS, and JavaScript, and integrates Baidu Analytics for user tracking. The site is mobile-optimized with a responsive design and clear navigation structure, contributing to a good user experience. However, it lacks advanced security headers and formal privacy or cookie policies, which are important for compliance and user trust. From a security perspective, the site uses HTTPS but does not implement additional security headers, and no contact or incident response information is provided. The absence of WHOIS registration data for the domain is a notable concern, as it reduces trustworthiness and raises questions about domain legitimacy. No forms or sensitive data collection mechanisms were detected, minimizing immediate risk exposure. Overall, the website is a functional and content-rich educational platform with moderate technical maturity and security posture. Strategic improvements in privacy compliance, security headers, and transparency of business information would enhance trust and compliance. The domain registration inconsistency should be investigated to ensure legitimacy and reduce risk.

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 business operates in the education sector, focusing on providing comprehensive Chinese language dictionary and reference services online. Its competitive advantage lies in the breadth of language resources and classical dictionary integration, appealing to a niche audience of language learners and educators. The business model appears to be content-driven, likely supported by advertising or affiliate partnerships, as indicated by external links to related educational and service sites. The partnership ecosystem includes various educational and service domains, enhancing its resource network. Growth indicators are not explicit, and no direct revenue streams or monetization methods are visible. The lack of formal business contact information and certifications suggests a small-scale operation primarily focused on content provision rather than commercial transactions.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communications. However, it lacks critical security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security, which are essential for mitigating common web vulnerabilities. No forms or user input fields reduce the attack surface, but the absence of privacy and cookie policies indicates compliance gaps, particularly with GDPR and related regulations. The missing WHOIS data for the domain is a significant red flag, potentially indicating privacy protection or registration issues that affect trust. Incident response readiness is not evident due to lack of contact channels for security issues. Overall, the security maturity is moderate but requires enhancements to meet best practices and regulatory compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies to improve legal compliance and user trust.
  2. Add essential security headers such as Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  3. Provide clear contact information including security incident response channels to enhance transparency and readiness.
  4. Investigate and resolve the missing WHOIS registration data to improve domain legitimacy and trustworthiness.
  5. Enhance accessibility features and conduct regular security audits to identify and mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a straightforward technology stack with HTML, CSS, and JavaScript, including a custom script and Baidu Analytics for tracking. The site is mobile-responsive and well-structured with clear navigation menus for dictionary lookup by radicals, strokes, and pinyin. No CMS or advanced frameworks were detected, indicating a possibly custom-built or static site. Performance is moderate with no evident optimization issues but could benefit from modern frontend frameworks or CDN usage. The lack of security headers and privacy mechanisms indicates technical debt in security and compliance areas. Hosting provider details are not discernible from the content. Overall, the technical infrastructure supports the business needs but requires modernization and security enhancements.
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.
