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 competitive online travel market, targeting budget-conscious travelers seeking multi-modal flight options and travel services. Its business model combines direct booking capabilities with partnerships, such as with Booking.com for hotels and Forter for fraud prevention. The company maintains a strong digital presence across multiple social media platforms and offers value-added services like disruption protection and price alerts. The market position is solid, supported by a medium-sized workforce and a decade-plus operational history. The company’s strategic partnerships and comprehensive service offerings indicate a mature and scalable business model with growth potential in the global travel sector.

Security posture

Kiwi.com demonstrates a high level of security maturity with enforced HTTPS, robust security headers, and integration of third-party fraud prevention and error monitoring tools. No exposed sensitive data or vulnerable libraries were detected in the website content. Privacy policies and cookie consent mechanisms align with GDPR requirements, though no explicit incident response or vulnerability disclosure contacts were found. The absence of public security contact points suggests an area for improvement in transparency and incident readiness. Overall, the security posture is strong, minimizing risks related to data breaches and fraud.

Recommendations

  1. Publish a public vulnerability disclosure policy and security.txt file to enhance transparency and encourage responsible reporting.
  2. Provide explicit incident response contact information, such as security@ or abuse@ email addresses, to improve trust and readiness.
  3. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  4. Enhance visibility of the Data Protection Officer contact details to strengthen GDPR compliance.
  5. Continue to monitor and optimize security headers and SSL/TLS configurations to maintain high security standards.

Use of Google Tag Manager and Forter indicates advanced marketing and fraud prevention capabilities. The site is well-structured with semantic HTML and accessibility 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.
