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

Quanmaitong.com is a professional SaaS platform focused on assisting Amazon sellers in China with comprehensive store management tools including real-time sales analytics, profit calculation, advertising management, and monitoring of unauthorized sellers. The platform is positioned as a one-stop cross-border service platform with a medium-sized company background founded in 2016. The website demonstrates a good level of digital maturity, employing modern web technologies such as Ruby on Rails, Turbo, and analytics tools from Google and Baidu. The hosting is provided by Alibaba Cloud, consistent with the company's Chinese market focus. Security posture is adequate with HTTPS and CSRF protections, but lacks advanced security headers and published security policies. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism detected. Overall, the site is professional and trustworthy with room for improvement in security and privacy transparency.

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. 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 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';…

  3. 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

The company, Shenzhen Duotang Technology Co., Ltd., operates in the e-commerce sector providing Amazon seller tools. Its business model is SaaS-based, targeting Amazon sellers who require multi-dimensional data analysis and operational assistance. The platform offers key services such as sales and profit analytics, advertising campaign management with time-based bidding, order and inventory management, automated review requests, and employee permission management. The company maintains a moderate market position with clear trust signals like ICP and public security filings. The website content and branding are consistent and tailored to the Chinese Amazon seller community. The company appears to have a stable operational history since 2016 with no evident subsidiaries or parent companies.

Security posture

The website employs HTTPS with a valid SSL certificate and uses CSRF tokens to protect forms, indicating a baseline security posture. However, it lacks implementation of common security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are recommended to mitigate common web vulnerabilities. No security or incident response policies are publicly disclosed, and no dedicated security contact channels are provided. The absence of a cookie consent mechanism also indicates partial privacy compliance. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security posture is moderate but could be enhanced by adopting best practices and transparency measures.

Recommendations

  1. Enable DNSSEC to improve domain name system security.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to harden the website against common attacks.
  3. Add a cookie consent banner/mechanism to comply with GDPR and other privacy regulations.
  4. Publish a clear security policy and incident response contact information to improve transparency and trust.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.

Technical notes

Notes

The website is built on a modern technology stack including Ruby on Rails with Turbo for frontend interactivity, Font Awesome for icons, and integrates analytics from Google and Baidu. Hosting is provided by Alibaba Cloud, which is appropriate for the target market. The site is mobile optimized with responsive design and good SEO practices including meta tags and Open Graph data. Performance is moderate, with asynchronous loading of analytics scripts. Accessibility features are basic but present. There is no detected CMS, indicating a custom or framework-based build. Overall, the technical infrastructure is solid with opportunities to improve security headers 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.
