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 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

    • 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

Tmall holds a dominant position in China's e-commerce sector, benefiting from Alibaba's extensive ecosystem and brand recognition. Its business model focuses on providing a marketplace for brands and merchants, emphasizing authenticity and quality. The platform integrates with Alibaba's payment and advertising services, creating a comprehensive shopping environment. The absence of explicit contact or privacy information in the analyzed content suggests these may be located on separate pages or require deeper navigation. The site targets a broad consumer base in China, with extensive product offerings and marketing campaigns.

Security posture

The website employs HTTPS and secure cookie attributes, indicating a commitment to secure communications and user data protection. Use of WebSocket with retry mechanisms and Content Security Policy nonces in scripts further enhance security. However, the lack of visible security headers such as CSP, HSTS, and X-Frame-Options in the provided HTML suggests room for improvement. No vulnerabilities or exposed sensitive data were detected. Privacy compliance indicators are minimal, with no clear privacy or cookie policies found in the analyzed content, which may impact GDPR compliance for international users.

Recommendations

  1. Publish clear and accessible privacy and cookie policies on the homepage or footer.
  2. Implement and enforce security headers like Content-Security-Policy, HSTS, and X-Frame-Options.
  3. Enhance accessibility features to meet international standards.
  4. Regularly audit third-party scripts and tracking technologies for vulnerabilities.
  5. Provide visible contact information and security incident response contacts.

Technical notes

Notes

The website uses a sophisticated tech stack including JavaScript, WebSocket, LocalStorage, and Alibaba's proprietary analytics frameworks. It loads resources from multiple Alibaba CDN domains and integrates with advertising and tracking networks such as tanx.com and mmstat.com. The site is optimized for performance and mobile use, with good SEO practices evident from meta tags and structured data. No CMS was explicitly detected, indicating a custom-built platform. Hosting details are not explicitly available but likely use Alibaba Cloud infrastructure.
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.
