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

九爱图纸 is a Chinese website specializing in sharing and downloading mechanical CAD drawings and engineering documents. It serves as a community and resource hub for mechanical design professionals and students, offering a large repository of over 27,000 documents. The platform supports user uploads and downloads, fostering knowledge exchange in the manufacturing and mechanical design sectors. The website operates primarily in Chinese and targets a specialized audience interested in mechanical CAD resources. Technically, the site is built on EmpireCMS and uses standard web technologies including HTML, CSS, and JavaScript, with integrations such as Baidu Share and 51.la analytics. The site shows basic mobile optimization and SEO practices but lacks advanced security headers and HTTPS enforcement, which are critical for protecting user data and maintaining trust. From a security perspective, the site lacks visible HTTPS enforcement, security headers, and anti-bot protections on login and upload forms. No privacy or cookie consent mechanisms are present despite the use of tracking scripts, indicating potential compliance gaps with privacy regulations. The absence of WHOIS registration data raises concerns about domain legitimacy, although the presence of Chinese ICP and public security filings partially mitigates this risk. Overall, the site presents moderate business credibility and content quality but requires significant improvements in security posture and privacy compliance to enhance trustworthiness and protect its user base.

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

九爱图纸 positions itself as a niche platform in the manufacturing and education sectors, focusing on mechanical CAD drawings and related engineering documents. Its business model revolves around user-generated content sharing and downloads, targeting mechanical engineers, designers, and students. The platform's competitive advantage lies in its extensive document repository and active user community with member rankings. Revenue streams are not explicitly detailed but may include advertising or premium memberships. The partnership ecosystem includes several related industrial and technical websites, enhancing its market reach. Growth indicators include a large number of documents and active user engagement, though technical and security limitations may impact scalability and user trust.

Security posture

The website's security maturity is low to moderate. Key vulnerabilities include lack of HTTPS enforcement, absence of security headers, no visible anti-CSRF or CAPTCHA protections on critical forms, and missing privacy compliance mechanisms. These gaps expose users to risks such as data interception, session hijacking, and automated abuse. The lack of incident response contacts or security policies further reduces readiness for security events. Compliance with Chinese regulatory requirements is partially evidenced by ICP and public security filings, but international privacy standards like GDPR appear unaddressed. The security culture seems minimal, with no visible certifications or advanced protections.

Recommendations

  1. Implement HTTPS site-wide with HSTS to secure user data and improve trust.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Introduce CAPTCHA or other bot mitigation on login and upload forms to prevent abuse.
  4. Deploy anti-CSRF tokens on all forms handling user input.
  5. Establish and publish clear privacy and cookie policies with consent mechanisms to comply with privacy regulations.

Technical notes

Notes

The website uses a traditional CMS (EmpireCMS) with standard web technologies. While functional, the site shows signs of technical debt such as lack of HTTPS enforcement and minimal mobile optimization. Performance is moderate but could be improved with modern front-end frameworks and optimization techniques. The use of third-party scripts like Baidu Share and 51.la analytics introduces tracking without visible user consent. The site structure and navigation are basic but adequate for the target audience. There is an opportunity to modernize the tech stack, improve accessibility, and enhance SEO for better reach and user experience.
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.
