Risk levelMedium

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

The website tudou.com is a well-established Chinese video sharing and streaming platform, closely associated with Youku and Alibaba Cloud Computing. It offers global short video content with services including video playback, publishing, search, and sharing. The platform targets a broad audience of video consumers and creators, leveraging Alibaba's infrastructure and brand strength. Technically, the site employs modern web technologies such as React and WebSocket for real-time analytics and user interaction tracking. However, the site lacks explicit privacy and cookie policies, which is a notable compliance gap. Security-wise, while the domain registration and hosting are legitimate and consistent with the business, the absence of security headers and explicit security policies suggests room for improvement. Overall, the site demonstrates a mature business presence but should enhance its privacy compliance and security posture to align with 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.com operates as a major player in the Chinese online video market, leveraging Alibaba's cloud infrastructure and Youku's brand. Its business model centers on video content delivery and user engagement through sharing and publishing. The platform benefits from strong market positioning due to its parent company and extensive user base. The lack of visible contact information and formal policies may impact user trust and regulatory compliance. The partnership ecosystem includes Youku and Alibaba-related domains, indicating integrated services and shared resources. Growth indicators are positive given the domain age and technical sophistication, but transparency improvements are advisable.

Security posture

The website's security posture is moderate. The domain is secured with transfer prohibitions and is hosted by Alibaba Cloud, a reputable provider. However, the absence of DNSSEC and security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces defense-in-depth. The site uses extensive tracking scripts and analytics, which may raise privacy concerns. No critical vulnerabilities or malware indicators were detected in the analyzed content. Incident response and security policies are not publicly disclosed, limiting transparency. Enhancing security headers and publishing clear security and privacy policies would strengthen the security posture.

Recommendations

  1. Enable DNSSEC to protect against DNS spoofing and improve domain security.
  2. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and HSTS.
  3. Publish comprehensive privacy and cookie policies to improve GDPR and privacy compliance.
  4. Provide clear contact information including security incident response contacts.
  5. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The site uses a modern tech stack with React and advanced browser APIs like MutationObserver and IntersectionObserver for dynamic content and analytics. WebSocket is used for real-time data transmission. Hosting is on Alibaba Cloud, ensuring scalability and reliability. Performance is moderate with good mobile optimization. SEO is basic with meta tags and Open Graph data present but no structured JSON-LD detected. Accessibility features are minimal. The site integrates extensive analytics and tracking mechanisms, indicating a mature data collection infrastructure but also raising privacy considerations.
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.
