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

Tudou.com is a well-established Chinese video sharing platform founded in 2004 and currently registered under Alibaba Cloud Computing (Beijing) Co., Ltd. The website offers video playback, publishing, search, and sharing services targeting a broad general audience interested in short videos. It is closely affiliated with Youku, another major Chinese video platform, as evidenced by shared infrastructure and branding. The technical infrastructure is modern, leveraging React and advanced web APIs, with hosting provided by Alibaba Cloud. The site employs extensive proprietary analytics and logging mechanisms to monitor user interactions. Security posture is solid with HTTPS enforcement and domain transfer protections, though DNSSEC is not enabled. However, the site lacks visible privacy and cookie policies, consent mechanisms, and explicit contact information, which are areas for improvement. Overall, Tudou.com presents a professional and trustworthy platform with room to enhance privacy compliance and 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

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 streaming and sharing service, competing in the Chinese market alongside Youku and other platforms. Its business model revolves around user-generated content and video distribution, monetized likely through advertising and partnerships. The company benefits from Alibaba's backing, providing strong market positioning and technological resources. The platform targets a wide demographic interested in short videos and media content. The absence of explicit business contact details on the site suggests a focus on user engagement rather than direct B2B interactions. The partnership with Youku and Alibaba enhances its ecosystem integration and market reach.

Security posture

The website demonstrates a good security posture with HTTPS enabled and domain status flags that prevent unauthorized transfers. The use of Alibaba Cloud hosting and proprietary analytics indicates a controlled environment. However, the lack of DNSSEC and absence of published security policies or incident response contacts reduce transparency. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The site does not provide a vulnerability disclosure policy or security.txt file, which are recommended best practices. Privacy compliance is weak due to missing privacy and cookie policies and lack of consent mechanisms, potentially exposing the company to regulatory risks.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing
  2. Publish comprehensive privacy and cookie policies clearly accessible on the website
  3. Implement a cookie consent mechanism to comply with GDPR and other privacy regulations
  4. Add a security.txt file and vulnerability disclosure policy to improve security transparency
  5. Provide clear contact information including security and incident response contacts to enhance trust

Technical notes

Notes

The website uses a modern tech stack including React and WebKit rendering, with advanced JavaScript features such as WebSocket logging, MutationObserver, and IntersectionObserver for analytics and user interaction tracking. Hosting is provided by Alibaba Cloud, ensuring robust infrastructure. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by appropriate meta tags and Open Graph data. The site uses extensive proprietary analytics scripts (goldlog) for user tracking. There is no detected CMS, suggesting a custom-built platform. Technical debt appears low, but improvements in accessibility and privacy compliance are advisable.
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.
