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

5 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 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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 operates as an essential entity in the transportation and hospitality sectors, leveraging an online platform business model that integrates multiple travel services. Its market position as a leading travel service provider in China is supported by a wide range of offerings and a large user base. The company benefits from a strong partnership ecosystem with multiple subsidiary domains dedicated to specific travel services. Revenue streams likely include commissions from bookings, advertising, and value-added services such as insurance and visa facilitation. The platform's growth is indicated by continuous content updates and marketing efforts. However, the lack of visible privacy and cookie policies may pose compliance risks in international markets.

Security posture

The website employs HTTPS and modern web security practices such as service workers and script integrity measures. However, the absence of explicit security headers like Content-Security-Policy and lack of published incident response or vulnerability disclosure information indicate room for improvement. No sensitive data exposure or vulnerable libraries were detected in the provided content. The extensive use of third-party marketing and analytics scripts suggests a need for ongoing security audits to mitigate supply chain risks. Overall, the security posture is good but could be enhanced with clearer privacy compliance and incident response transparency.

Recommendations

  1. Implement and publicly disclose comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR and global privacy compliance.
  2. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  3. Publish a security policy and incident response contact information to enhance transparency and trust.
  4. Conduct regular security audits of third-party scripts and dependencies to reduce supply chain vulnerabilities.
  5. Enhance accessibility features to meet international standards and improve user experience for all users.

Key observations

  1. Website is a large, enterprise-level online travel service platform targeting Chinese and international travelers.
  2. Content is rich with multiple travel-related services including hotels, flights, trains, car rentals, cruises, and insurance.
  3. Website uses modern web technologies and includes extensive tracking and marketing scripts.
  4. No explicit privacy or cookie policy found in the provided HTML content.
  5. WHOIS data is not available, which is unusual for a major brand but may be due to privacy protection or query limitations.
  6. No direct contact emails or phone numbers found in the visible content.
  7. No security.txt or vulnerability disclosure information found.
  8. Website is accessible without WAF or security challenge blocking.
  9. Content is safe for general audiences with no adult or NSFW material.
Technical notes

Notes

The website is built using modern JavaScript frameworks, likely React, and employs service workers for offline or performance enhancements. It integrates multiple external domains for content delivery, marketing, and analytics. Performance appears moderate with some optimization potential, especially for mobile responsiveness and accessibility. SEO is supported by proper meta tags and structured navigation. The absence of a detected CMS suggests a custom or proprietary platform. Hosting details are not explicit but likely involve a CDN and cloud infrastructure given the domain patterns. Technical risks include reliance on multiple third-party scripts and incomplete security header implementation.
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.
