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

8 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 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 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

Airbnb holds a dominant market position in the short-term rental and experiences sector, with a business model focused on peer-to-peer lodging and travel experiences. Revenue streams include service fees from bookings and hosts. The platform targets a broad audience of travelers seeking unique accommodations and hosts looking to monetize their properties. The company benefits from a vast partnership ecosystem and strong brand recognition. Growth indicators include continuous expansion of listings and geographic coverage. Strategic observations highlight the importance of maintaining regulatory compliance and enhancing transparency to sustain trust and market leadership.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of security headers, and isolation of third-party scripts via Partytown. Error reporting and monitoring are implemented through Bugsnag, indicating proactive incident detection. No vulnerabilities or exposed sensitive data were identified in the analyzed content. Compliance gaps include the absence of visible privacy and cookie policies, which are critical for GDPR and other data protection regulations. Incident response contact information is not publicly available, which could delay response to security issues. Overall, the security maturity is high but could be improved by publishing comprehensive compliance documentation and establishing clear security communication channels.

Recommendations

  1. Publish clear and accessible privacy and cookie policies linked from the homepage to improve compliance and user trust.
  2. Implement a cookie consent mechanism to align with GDPR and other privacy regulations.
  3. Provide explicit contact information for security incidents and data protection inquiries.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Regularly review and update third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using modern frontend technologies including React and Partytown, which enhances performance and security by isolating third-party scripts. The use of Google Tag Manager and Bugsnag indicates mature analytics and error monitoring capabilities. The site is well-optimized for mobile devices and accessibility, with comprehensive SEO metadata and multilingual support. Hosting appears to be managed via Airbnb's own infrastructure or CDN services. Performance is fast with preloading of critical resources. Technical risks are minimal, but continuous monitoring of third-party libraries and compliance with evolving privacy standards is recommended to maintain operational integrity.
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.
