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

Kiwi.com s.r.o. is a Czech Republic-based online travel agency specializing in providing cheap flights, hotels, trains, and car hire services with 24/7 customer support and disruption protection. The company leverages innovative search technology and an interactive map to offer travelers convenient and affordable travel options. The website is professionally designed, mobile-optimized, and offers a comprehensive user experience with clear navigation and rich content. Technical infrastructure includes modern JavaScript frameworks such as React, integration with Google Tag Manager, and fraud prevention via Forter, indicating a mature digital presence. Security posture is strong with HTTPS enforcement, security headers, and privacy compliance including GDPR adherence. However, the absence of WHOIS domain registration data and lack of explicit incident response or vulnerability disclosure information slightly reduce transparency. Overall, Kiwi.com presents a trustworthy and professional online travel platform with room for improvement in security transparency and direct contact information.

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

4 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"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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

Kiwi.com operates in the transportation sector as a large online travel agency with a business model focused on aggregating and offering travel services including flights, hotels, trains, and car rentals. The company targets travelers seeking affordable and flexible travel solutions, supported by disruption protection guarantees. Its market position is strong with a recognized brand and extensive social media presence. Partnerships with Booking.com and related domains enhance its service offerings. The company was founded in 2010 and maintains a consistent brand image and high-quality content. Revenue streams likely include commissions from bookings and ancillary services. The absence of direct contact details on the website suggests a focus on digital self-service and automated support channels.

Security posture

Kiwi.com demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and a dedicated security policy page. The website includes cookie consent mechanisms aligned with GDPR requirements, indicating good privacy practices. No vulnerabilities or exposed sensitive data were detected in the analyzed content. However, the lack of publicly available incident response contacts and vulnerability disclosure policies represents a gap in transparency and readiness communication. The use of Forter for fraud prevention and Google Tag Manager for analytics shows integration of security and monitoring tools. Overall, the security maturity is high but could be enhanced by publishing explicit security contacts and disclosure policies.

Recommendations

  1. Publish explicit incident response and security contact information to improve transparency and trust.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Add verified company contact emails and phone numbers on the website for improved customer and security communication.
  4. Consider obtaining and displaying recognized security certifications to strengthen trust signals.
  5. Maintain regular WHOIS data updates and ensure domain registration transparency to avoid suspicion.

Technical notes

Notes

The website uses a modern technology stack centered on React for frontend rendering, supported by Google Tag Manager for analytics and Forter for fraud prevention. The site is well-optimized for performance and mobile responsiveness, with preloading of fonts and images to enhance user experience. Accessibility features are present, and SEO is supported by comprehensive meta tags and structured data in JSON-LD format. Hosting details are not explicitly identified but the use of multiple CDNs and security providers indicates a robust infrastructure. No technical debt or deprecated technologies were observed. The site’s performance is fast, and the technical implementation aligns with best practices for a high-traffic commercial travel platform.
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.
