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

掌桥科研 is a Chinese one-stop academic research service platform offering access to over 300 million Chinese and foreign literature documents. It provides services such as literature search and download, document translation and conversion, citation and indexing, technology novelty search, and AI-powered writing tools including thesis writing, topic selection, and plagiarism checking. The platform targets academic researchers and students in China, positioning itself as a leading provider in the academic research support sector. Technically, the website uses standard web technologies like HTML5, CSS3, JavaScript, and Bootstrap, with moderate performance and good mobile optimization. However, the absence of WHOIS registration data and lack of visible privacy and cookie policies indicate potential compliance and trust concerns. Security posture is moderate with no advanced security headers detected and unknown SSL configuration. Overall, the platform offers valuable academic services but should improve transparency and security compliance to enhance trust and regulatory adherence.

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. 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 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';…

  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 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 operates in the education sector, focusing on academic research services in China. It leverages a business model based on membership and paid services such as document downloads, AI writing assistance, and plagiarism detection. The target customers are academic researchers, students, and institutions requiring comprehensive literature and research support. The website demonstrates consistent branding and a broad service portfolio, including AI tools and citation databases, which may provide competitive advantages. However, the lack of publicly available WHOIS data and contact information may hinder trust and limit business credibility. There is no evidence of partnerships or subsidiaries from the data provided. Growth potential exists given the increasing demand for AI-assisted academic tools in China.

Security posture

The website currently exhibits a moderate security maturity level. HTTPS is presumably enabled (based on canonical URLs using https), but no explicit security headers such as Content-Security-Policy, X-Frame-Options, or HSTS were detected in the provided data. There is no exposed sensitive data or known vulnerable libraries visible in the HTML content. The absence of privacy and cookie policies, as well as incident response contacts, indicates gaps in compliance and readiness. No vulnerability disclosure or security.txt files were found. Overall, the security posture is functional but lacks advanced protections and transparency, which could expose the platform to compliance risks and reduce user trust.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to comply with GDPR and other regulations.
  2. Add and configure security headers such as Content-Security-Policy, X-Frame-Options, and HSTS to enhance protection.
  3. Ensure WHOIS registration data is complete and publicly available to improve domain trustworthiness.
  4. Provide clear contact information including support emails and incident response channels for security and abuse reporting.
  5. Conduct regular security audits and consider publishing a vulnerability disclosure policy or security.txt file.

Technical notes

Notes

The website uses a standard technology stack with HTML5, CSS3, JavaScript, and Bootstrap for responsive design. The site is mobile optimized and has a clear navigation structure with extensive content related to academic literature and AI writing tools. Performance is moderate, with external resources loaded from a CDN subdomain. There is no detected CMS or advanced frameworks. The site lacks visible advanced accessibility features and SEO could be improved by adding more structured data and meta tags. The absence of security headers and privacy compliance features indicates technical debt in security and regulatory areas. Hosting provider details are not discernible from the provided data.
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.
