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

Ctrip.com is a leading Chinese online travel service platform established in 1999, offering a comprehensive range of travel-related services including hotel bookings, flight and train ticket reservations, vacation packages, business travel management, car rentals, cruises, insurance, and visa services. The website targets a broad audience of travelers primarily in China, providing extensive travel options and information. The platform demonstrates a mature digital infrastructure with modern web technologies such as React, service workers, and integration with major analytics tools like Google Tag Manager and Baidu Analytics. The site is well-branded and professionally designed, offering a good user experience with clear navigation and mobile optimization. Security posture is solid with HTTPS enabled and domain management protections, though there is room for improvement in DNS security and security headers. Privacy compliance is currently weak due to the absence of explicit privacy and cookie policies and consent mechanisms. Overall, the site is trustworthy and professionally maintained but should enhance transparency and compliance to align with global privacy standards.

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

6 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 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

Ctrip holds a dominant market position in China's online travel industry, serving over 90 million members. Its business model revolves around providing a one-stop travel booking platform with diversified services including hotels, flights, trains, cruises, and travel insurance. The company leverages partnerships and extensive service offerings to maintain competitive advantages. The platform's integration of business travel management and financial services indicates a broad revenue stream and enterprise focus. The website's content and navigation reflect a customer-centric approach targeting both leisure and business travelers. The long domain age and consistent branding reinforce its market credibility. However, the lack of visible contact information and compliance documentation on the homepage suggests areas for operational transparency improvement.

Security posture

The website employs HTTPS with a valid SSL configuration and strong domain status protections to prevent unauthorized domain changes. Use of service workers and modern JavaScript frameworks indicates a contemporary security-aware development approach. However, the absence of DNSSEC and missing security headers such as Content-Security-Policy and X-Frame-Options are notable gaps. No explicit security policies or incident response contacts are published, which could hinder rapid response to security incidents. The site does not expose sensitive data in the HTML content and uses secure forms for user input. Overall, the security posture is good but could be enhanced by adopting additional DNS and HTTP security measures and publishing clear security policies.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies prominently on the website with clear consent mechanisms to improve compliance.
  3. Implement and publish a security policy and incident response contact information to enhance transparency and readiness.
  4. Add security HTTP headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web vulnerabilities.
  5. Consider adding visible and verified contact information including support emails and phone numbers to improve user trust and business credibility.

Technical notes

Notes

The website uses a modern technology stack including React for UI rendering, service workers for offline capabilities, and integrates with major analytics platforms like Google Tag Manager and Baidu Analytics. The hosting appears to be managed via MarkMonitor and Alibaba DNS services, indicating enterprise-grade infrastructure. Performance is moderate with some preloading of scripts and stylesheets. Mobile optimization is good with responsive design elements. Accessibility features are basic but present. SEO is supported by proper meta tags and canonical links. There is no detected CMS, suggesting a custom-built platform. Technical risks include lack of DNSSEC and missing security headers, which should be addressed to reduce attack surface.
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.
