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

PaperPass.com is a mature Chinese academic service platform specializing in plagiarism detection, paper rewriting, AI-generated content detection, and related academic tools. Established in 2005, it serves a large user base including students, educators, and researchers, positioning itself as a leading provider in the Chinese academic integrity market. The platform offers a variety of services such as free plagiarism checks, intelligent rewriting, AI detection, format checking, and AI-generated presentation tools, supported by a robust technical infrastructure including Tencent Cloud storage and multiple analytics services. Technically, the website employs modern web technologies including Bootstrap, jQuery, and integrates third-party analytics and CAPTCHA services to enhance user experience and security. The platform supports multiple access methods including PC web, mobile web, and WeChat mini-programs, indicating a good level of digital maturity and mobile optimization. However, some areas such as accessibility and security headers could be improved. From a security perspective, the site enforces HTTPS and uses CAPTCHA to mitigate automated abuse. Nonetheless, it lacks visible security headers and does not provide explicit privacy or cookie consent mechanisms, which are important for regulatory compliance and user trust. No incident response or vulnerability disclosure information is publicly available, which could be a gap in transparency and security readiness. Overall, PaperPass.com presents a professional and functional academic service platform with a solid business foundation and technical implementation. To enhance trust and compliance, it should improve privacy disclosures, implement security best practices, and publish clear security policies. These steps will strengthen its security posture and regulatory alignment, supporting sustained growth and user confidence.

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

6 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

Business profile

PaperPass operates in the education sector, focusing on academic integrity services such as plagiarism detection and AI content analysis. Its business model is primarily service-based, offering online tools for paper checking and rewriting. The company targets students, educators, and academic institutions in China, leveraging a large user base and partnerships such as with Xiaomo.com for AI-generated papers. The platform's longevity since 2005 and its extensive service offerings indicate a stable market position. Revenue streams likely include paid premium services beyond free checks. The company maintains a moderate size with a regional focus in China, supported by a parent company Beijing Zhichi Shuhui Technology Co., Ltd. The partnership ecosystem and multiple service integrations suggest strategic growth and diversification within the academic technology niche.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforcement and CAPTCHA integration to protect user login. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security reduces its defense-in-depth capabilities. The lack of visible privacy and cookie consent mechanisms indicates potential compliance gaps with GDPR and similar regulations. No public incident response or vulnerability disclosure policies were found, which may impact transparency and user trust. The use of multiple third-party analytics scripts without explicit consent could raise privacy concerns. Overall, while basic security measures are in place, there is room for improvement in policy transparency, header implementation, and privacy compliance to enhance the security posture.

Recommendations

  1. Implement comprehensive privacy and cookie policies with visible consent mechanisms to ensure regulatory compliance.
  2. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen security posture.
  3. Publish a clear security policy and incident response contact information to improve transparency and user trust.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities and privacy risks.
  5. Enhance accessibility features to improve compliance and user experience across diverse user groups.

Technical notes

Notes

The website uses a modern technology stack including Bootstrap for responsive design, jQuery for scripting, and integrates multiple analytics and CAPTCHA services from Baidu, CNZZ, Bing, and Tencent. Hosting leverages Tencent Cloud services, including COS for static content delivery. The site supports multiple platforms including PC, mobile web, and WeChat mini-programs, indicating good digital maturity. Performance is moderate with no major issues detected. However, the absence of a CMS or framework identification suggests a custom or proprietary solution. Technical debt appears low but could be improved by adding security headers and privacy compliance features. Overall, the technical infrastructure supports the business needs effectively but has opportunities 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.
