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

The website cainiaoya.com is a Chinese programming tutorial platform offering a wide range of educational content covering front-end, back-end, mobile development, databases, and various programming languages and frameworks. It targets programmers and IT learners seeking comprehensive technical tutorials and documentation. The business model is centered on providing free or accessible educational resources, positioning itself as a well-known player in the Chinese programming education market. Technically, the site uses WordPress CMS with the layui framework, integrates MathJax for math rendering, and employs Baidu Analytics for user tracking. The site is mobile-optimized with good navigation and content relevance. Security posture is moderate; HTTPS is assumed but no advanced security headers or DNSSEC are enabled. Privacy compliance is weak due to the absence of explicit privacy and cookie policies or consent mechanisms. No contact or incident response information is provided, which limits trust and compliance. Overall, the site is functional and content-rich but would benefit from enhanced security and privacy practices.

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. 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.

Breach exposure

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

Leaked records that mention cainiaoya.com, from OffSeq Breach.

No leaked records found

Breach holds no records for cainiaoya.com right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Cainiaoya.com operates in the education and technology sectors, focusing on programming tutorials and developer learning resources. Its competitive advantage lies in the breadth and depth of content across multiple programming languages and technologies, catering primarily to Chinese-speaking developers. The business model likely relies on advertising and possibly affiliate links, though no explicit monetization details are found. The site is relatively new (established 2023) but shows signs of steady content development. There is no evidence of parent or subsidiary companies. The partnership ecosystem is not explicitly disclosed. The platform serves a broad developer audience, from beginners to advanced users, and maintains consistent branding and content quality.

Security posture

The website demonstrates a basic to moderate security posture. It uses HTTPS (assumed from external resources), disables certain mobile zoom features to improve UX and possibly security, and includes Baidu Analytics scripts. However, it lacks DNSSEC, security headers like CSP or X-Frame-Options, and does not provide a security policy or incident response contacts. No vulnerability disclosure or security.txt files are present. The absence of privacy and cookie policies indicates compliance gaps with GDPR and similar regulations. No exposed sensitive data or known vulnerabilities were detected in the provided content. The security score is moderate but could be improved with standard best practices.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish clear and comprehensive privacy and cookie policies with user consent mechanisms to improve compliance.
  4. Add visible and verified contact information including security incident response contacts and data protection officer details.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS with the layui UI framework, leveraging modern web technologies including HTML5, CSS3, and JavaScript. It uses MathJax for rendering mathematical notation and integrates Google Fonts, Font Awesome, and Material Icons for styling and icons. Baidu Analytics is used for traffic analysis. The site is mobile-optimized with responsive design and disables certain mobile zoom gestures for better user experience. Performance is moderate, with external CDN usage for static assets. No major technical debt or deprecated technologies were detected. Opportunities exist to improve accessibility and SEO further by adding ARIA roles and enhancing meta tags.
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.
