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

Baidu is a leading Chinese search engine providing extensive internet search and information retrieval services. The website is designed primarily for Chinese-speaking users and offers a comprehensive database of Chinese web pages. Baidu holds a dominant market position in China’s search engine market and operates at an enterprise scale. The website demonstrates excellent content quality, professional design, and consistent branding, reflecting its status as a major technology company. Technically, the site uses modern web technologies including HTML5, CSS3, and JavaScript, and is optimized for fast performance and good mobile experience. Security-wise, the site enforces HTTPS but lacks visible security headers in the provided data, suggesting room for improvement in hardening. Privacy and compliance documentation such as privacy and cookie policies are not explicitly found in the main HTML content, which may impact privacy compliance perception. WHOIS data is unavailable due to registry restrictions, which is common for large Chinese domains but reduces transparency. Overall, Baidu’s website is professional, secure, and trustworthy, with minor gaps in privacy disclosures and security headers.

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 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

Baidu operates as a technology enterprise focused on internet search and related online services. Its business model centers on providing search engine capabilities to a broad Chinese audience, monetizing through advertising and other internet services. Baidu’s market position is strong as the leading Chinese search engine, competing primarily with other domestic and international search providers. The company targets general internet users in China and likely generates revenue from advertising and value-added services. The website’s ecosystem includes multiple trusted subdomains hosting static content and services. Baidu’s brand is well-established with consistent visual identity and high content relevance. The lack of explicit contact information and privacy policies on the homepage suggests these may be located deeper within the site or handled via separate portals. Baidu’s strategic partnerships and subsidiaries are not explicitly identified in the provided data.

Security posture

The website enforces HTTPS, ensuring encrypted communication and basic transport security. However, no explicit security headers such as Content-Security-Policy, X-Frame-Options, or Strict-Transport-Security were detected in the provided HTML snippet, which are recommended best practices to mitigate common web vulnerabilities. No exposed sensitive data or vulnerable libraries were identified. The site does not appear to have forms collecting sensitive data on the homepage, reducing immediate risk exposure. The absence of visible privacy and cookie policies may indicate compliance gaps, especially regarding GDPR or similar regulations. WHOIS data is restricted, which is typical for large domains but reduces transparency. Overall, Baidu’s security posture is solid but could be enhanced by implementing additional HTTP security headers and improving privacy disclosures.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance web security.
  2. Publish clear and comprehensive privacy and cookie policies accessible from the homepage to improve privacy compliance and user trust.
  3. Provide explicit contact information including security incident response contacts to facilitate communication and transparency.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible security reporting.
  5. Enhance WHOIS transparency if possible or provide official domain registration information on the corporate site to improve legitimacy perception.

Technical notes

Notes

The website uses a modern and performant technical stack with HTML5, CSS3, and JavaScript. It loads resources from multiple trusted subdomains under baidu.com and bdstastic.com, indicating a well-structured content delivery network. The site is optimized for fast loading and good mobile responsiveness. No CMS or third-party frameworks were explicitly detected in the provided HTML snippet. The site lacks visible structured data such as JSON-LD or Open Graph tags, which could improve SEO and social media integration. Accessibility features appear adequate based on CSS and layout, but no ARIA roles or landmarks were explicitly found. Overall, the technical implementation is robust with opportunities to enhance SEO and accessibility further.
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.
