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

知识星球 is a Chinese technology platform focused on connecting creators with their core fans to enable knowledge monetization and high-quality community management. The platform targets creators such as artists, craftsmen, teachers, and researchers, offering tools for content creation, paid communities, and fan engagement. It holds a strong market position in China's knowledge economy sector with a mature business founded in 2005 and operated by 深圳市大成天下信息技术有限公司. Technically, the website employs standard web technologies including jQuery and QR code generation libraries, supports iOS and Android apps, and is hosted under DNSPod, Inc. The site is moderately optimized for performance and mobile devices, with good SEO practices but lacks advanced accessibility features. No CMS or major frameworks are explicitly detected. From a security perspective, the site uses HTTPS and has domain transfer protections but lacks DNSSEC and explicit security headers such as CSP or HSTS. There is a dedicated security emergency response center linked, but no direct security contact emails are found. Privacy compliance is basic with a privacy policy present but no cookie consent mechanism. No critical vulnerabilities or blocking mechanisms are detected. Overall, the website is professional, trustworthy, and well-established with minor improvements recommended in security headers, DNSSEC, and privacy compliance to enhance its security posture and user 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

3 findings rated critical or high. Fix these first.

  1. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

知识星球 operates in the technology sector as a knowledge monetization and community management platform. Its competitive advantage lies in targeting creators with a scalable model allowing paid fan communities ('付费星球'). Revenue streams likely include paid subscriptions and transaction fees. The platform serves a niche but growing market of knowledge workers and creators in China. Partnerships with Tencent app stores and payment processors are implied. The company maintains ICP and public security records, indicating regulatory compliance. Growth indicators include a mature domain and active app presence. Strategic observations suggest focusing on expanding security and privacy features to maintain trust and comply with evolving regulations.

Security posture

The security maturity of 知识星球 is moderate. HTTPS is enforced and domain transfer protections are in place, which are positive indicators. However, the absence of DNSSEC and security headers such as Content Security Policy and HSTS reduces the overall security posture. The presence of a security emergency response center is a good practice, but lack of direct security contact emails limits incident response readiness. No visible vulnerabilities or malware are detected. Privacy compliance is partial, with no cookie consent mechanism. The platform should prioritize implementing DNSSEC, security headers, and explicit privacy controls to improve compliance and reduce risk.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve DNS security.
  2. Implement security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to mitigate common web attacks.
  3. Add a cookie consent banner/mechanism to comply with privacy regulations and improve user transparency.
  4. Publish explicit security contact emails (e.g., security@domain) to facilitate vulnerability reporting and incident response.
  5. Conduct regular security audits of third-party libraries and dependencies to prevent vulnerabilities.

Technical notes

Notes

The website uses a traditional web stack with jQuery and QR code generation scripts. The presence of commented-out Swiper and retina scripts suggests ongoing development or optimization. Hosting and domain registration are stable with DNSPod, Inc. Performance is moderate with good mobile optimization. SEO is supported by meta tags and structured content. No CMS or advanced frameworks are detected, indicating a custom or lightweight implementation. Accessibility is basic and could be improved. The site lacks advanced security headers and DNSSEC, representing technical debt in security. Overall, the technical infrastructure supports the business needs but has room for modernization and enhanced security.
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.
