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

Tudou.com is a well-established Chinese video sharing platform, founded in 2004 and operated under Alibaba Cloud Computing (Beijing) Co., Ltd. It offers a comprehensive video service including playback, publishing, search, and sharing, targeting a broad general audience interested in short videos. The platform is closely related to Youku, a major player in the Chinese online video market, indicating a strong market position and enterprise scale. The website demonstrates a mature technical infrastructure using React and Alibaba's cloud hosting, with extensive use of proprietary analytics and tracking technologies. Security posture is moderate with domain protections in place but lacks visible security headers and explicit security policies. Privacy compliance is weak due to absence of privacy and cookie policies on the main page. Overall, Tudou.com is a credible and professional platform with room for improvement in privacy transparency and security best practices.

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 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

  3. 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.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

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

Tudou operates in the media sector as a video sharing and streaming platform, leveraging Alibaba's cloud infrastructure and analytics ecosystem. Its business model revolves around user-generated content and video distribution, monetized likely through advertising and partnerships. The platform targets a wide demographic in China, focusing on short video content consumption. Its relationship with Youku strengthens its market presence and operational capabilities. The company benefits from Alibaba's enterprise scale and technological resources, positioning it as a leading player in the Chinese digital media landscape.

Security posture

The website shows domain registration protections such as clientTransferProhibited and serverUpdateProhibited statuses, indicating good domain security hygiene. However, the absence of DNSSEC and lack of visible security headers reduce the overall security posture. No explicit security policies or incident response contacts are found, which is a gap in transparency and readiness. The site uses HTTPS (implied by modern standards and hosting) but no explicit SSL configuration details are available. Extensive tracking and analytics scripts are present, which may raise privacy concerns. No critical vulnerabilities or malware indicators were detected in the content.

Recommendations

  1. Publish clear and comprehensive privacy and cookie policies to improve privacy compliance and user trust.
  2. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Enable DNSSEC to enhance domain name system security.
  4. Provide explicit security policy and incident response contact information to improve transparency and readiness.
  5. Review and optimize tracking scripts to balance analytics needs with user privacy and compliance requirements.

Technical notes

Notes

The website uses React framework and is hosted on Alibaba Cloud, indicating a modern and scalable infrastructure. It employs advanced JavaScript tracking and analytics mechanisms including WebSocket communications and mutation observers for user interaction tracking. Performance is moderate with good mobile optimization and basic accessibility features. SEO optimization is basic but present through meta tags and Open Graph data. The site lacks CMS identification but is likely custom-built or uses proprietary Alibaba platforms. Hosting and DNS are managed by Alibaba Cloud, a reputable provider. Overall, the technical implementation supports a large-scale media platform but could benefit from enhanced security and privacy technical controls.
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.
