Risk levelMedium

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

菜鸟教程 (cainiaoplus.com) is a Chinese-language online educational platform specializing in programming tutorials and technical references. It offers a wide range of tutorials covering front-end, back-end, data analysis, mobile development, and databases, targeting software developers and learners seeking comprehensive programming knowledge. The website is well-structured with clear navigation and extensive content, positioning itself as a valuable resource in the Chinese programming education market. Technically, the site uses standard web technologies including Bootstrap, jQuery, and Baidu Analytics, with moderate performance and good mobile optimization. Security posture is basic with HTTPS enabled but lacks advanced security headers and DNSSEC. Privacy compliance is minimal with no cookie consent mechanism and only a basic privacy policy present. Overall, the site is legitimate and functional but could improve in security and privacy transparency.

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 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 cainiaoplus.com, from OffSeq Breach.

No leaked records found

Breach holds no records for cainiaoplus.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

The platform operates in the education and technology sectors, focusing on delivering programming knowledge through online tutorials and tools. Its business model is content-driven, likely monetized through advertising or partnerships, as indicated by numerous external friendly links. The target audience includes beginner to intermediate programmers primarily in China. The domain is relatively new (2023), consistent with the website's content freshness. The site maintains partnerships with related tutorial and tool domains, enhancing its ecosystem. While no direct revenue streams or certifications are evident, the site demonstrates a solid market presence in Chinese programming education.

Security posture

The website employs HTTPS, ensuring encrypted communication, but lacks DNSSEC and security headers such as Content Security Policy or HSTS, which are important for mitigating common web attacks. No incident response or security policies are published, and no contact channels for security issues are provided. The use of Baidu Analytics indicates user tracking without explicit cookie consent, which may raise privacy concerns under GDPR. No vulnerabilities or exposed sensitive data were detected in the content. The security maturity is basic, suitable for an educational site but with room for improvement to enhance trust and compliance.

Recommendations

  1. Enable DNSSEC to improve domain name system security.
  2. Implement security headers like CSP, HSTS, and X-Frame-Options to harden the website against attacks.
  3. Add a cookie consent banner to comply with privacy regulations and inform users about tracking.
  4. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  5. Enhance contact information availability to improve business credibility and user trust.

Technical notes

Notes

The website uses a classic web technology stack with Bootstrap 3.3.7 and jQuery 1.11.3, which are somewhat dated but still functional. The site loads resources from reputable CDNs and uses Baidu Analytics for user tracking. The HTML is well-structured with meta tags for SEO and mobile responsiveness. Performance is moderate, with potential improvements by updating libraries and optimizing assets. Accessibility is basic, with no explicit ARIA roles or advanced accessibility features detected. The site does not appear to use a CMS, indicating a custom or static site architecture. Hosting provider details are not explicit from the data. Overall, the technical implementation is solid but could benefit from modernization and enhanced security practices.
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.
