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

3D溜溜网 (3d66.com) is a Chinese online platform offering a vast collection of design materials including 3D models, CAD drawings, textures, and design case studies. It serves as a knowledge-sharing and resource hub for designers and creative professionals, positioning itself as a leading design resource platform in the Chinese market. The website provides downloadable content and inspiration for design projects, targeting a broad audience of designers. Technically, the site uses standard web technologies including JavaScript, Baidu Analytics, and service workers, with basic mobile optimization and moderate performance. Security posture is limited due to lack of visible HTTPS enforcement and missing security headers, and no privacy or cookie policies were detected, indicating compliance gaps. WHOIS data is unavailable, which reduces trustworthiness from a domain registration perspective. Overall, the site appears functional and content-rich but would benefit from improved 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

5 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
    • 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';…

  2. 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 operates as a content distribution and community knowledge base for design professionals, leveraging a large repository of design assets. Its business model likely includes freemium or paid downloads, advertising, or memberships. The site targets designers in China, offering a comprehensive range of design resources. The lack of explicit business registration or contact information online suggests a need for improved transparency. The use of Baidu Analytics aligns with its Chinese market focus. No clear partnerships or subsidiaries were identified from the data. The platform's market position is strong within its niche, but domain registration opacity and missing compliance documentation may impact credibility.

Security posture

The website currently lacks visible HTTPS enforcement confirmation and security headers such as Content-Security-Policy or X-Frame-Options. No evidence of secure forms or input validation was found. The absence of privacy and cookie policies indicates non-compliance with GDPR and related regulations. The use of third-party analytics (Baidu Analytics) without clear user consent mechanisms further reduces privacy compliance. No incident response or security contact information is provided. These factors suggest a low security maturity level and potential vulnerabilities related to data protection and user privacy. Recommendations include implementing HTTPS, adding security headers, publishing privacy and cookie policies, and establishing incident response contacts.

Recommendations

  1. Implement HTTPS with a valid SSL certificate and enforce secure connections site-wide.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Publish comprehensive privacy and cookie policies with clear user consent mechanisms to comply with GDPR.
  4. Provide clear contact information including security and incident response contacts.
  5. Conduct regular security audits to identify and remediate vulnerabilities and improve overall security posture.

Technical notes

Notes

The website uses a standard modern web stack with JavaScript, CSS, and HTML5, including service workers for offline capabilities. Baidu Analytics is integrated for user tracking. The site has moderate performance and basic mobile optimization. No CMS or hosting provider information was detected. The site structure and meta tags support good SEO. Accessibility features are basic but present. The absence of advanced frameworks or CMS suggests a custom or lightweight implementation. Technical debt appears moderate with opportunities for modernization, especially in security and privacy compliance.
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.
