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

大牛创业笔记 is a Chinese entrepreneurship and self-media education platform launched in 2023, offering a variety of tutorials, membership courses, and original content aimed at both beginners and experienced entrepreneurs. The website positions itself as a popular online training resource in China, focusing on self-media operations and entrepreneurial projects. Technically, the site is built on WordPress using the Zibll theme, leveraging common libraries such as jQuery and Bootstrap, and is hosted via DNSPod, Inc. The site demonstrates moderate performance and good mobile optimization but lacks advanced accessibility features. Security-wise, HTTPS is enabled, but additional HTTP security headers are missing, and DNSSEC is not enabled, indicating room for improvement. Privacy compliance is weak due to the absence of privacy and cookie policies. Overall, the site is functional and professional but should enhance its compliance and security posture to build greater trust.

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 targets Chinese entrepreneurs interested in self-media and online business projects, offering paid memberships and free tutorials. Its business model relies on content sharing and membership subscriptions. The site shows consistent branding and a clear market position as a niche educational resource. While the domain is newly registered in 2023, this aligns with the business age. No direct partnerships or subsidiaries are identified. The lack of explicit contact details and privacy policies may limit trust for some users. The site’s content and membership offerings suggest a focus on growth and monetization through educational services.

Security posture

The website employs HTTPS, ensuring encrypted communication, but lacks several recommended security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options. DNSSEC is not enabled, which could expose DNS queries to spoofing. No exposed sensitive data or vulnerable libraries were detected in the provided content. The absence of a security policy or incident response contact reduces transparency. Forms appear to be standard WordPress forms without advanced security features visible. Overall, the security posture is moderate but could be significantly improved by implementing best practices and compliance measures.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing attacks.
  2. Implement comprehensive privacy and cookie policies with clear consent mechanisms to comply with GDPR and other regulations.
  3. Add HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the site against common web attacks.
  4. Publish a security policy and incident response contact information to improve transparency and trust.
  5. Enhance accessibility features to meet standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Zibll theme, with standard libraries like jQuery and Bootstrap for UI components. The site loads external CSS and JS from its own domain and some Baidu domains for resources. Performance is moderate with good mobile responsiveness. SEO is supported by meta tags and canonical links. However, accessibility features are basic, and some modern security headers are missing. The hosting provider is DNSPod, Inc., a reputable registrar and DNS provider. The domain is relatively new but consistent with the business age. Overall, the technical infrastructure is solid but could benefit from security and compliance 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.
