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

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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';…

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 hospitality sector as a pioneer in peer-to-peer short-term rentals and experiences. Its competitive advantages include a vast global inventory, strong brand recognition, and a user-friendly platform. Revenue streams primarily come from booking fees charged to guests and hosts. The target customer segments include leisure travelers, business travelers, and hosts seeking to monetize their properties. Growth indicators are positive, supported by continuous platform enhancements and expansion into new markets and services. The partnership ecosystem includes integrations with payment processors and marketing tools, though no direct partner domains were identified in the analyzed content. Strategic observations highlight Airbnb's focus on innovation and user experience to maintain market leadership.

Security posture

The website exhibits a mature security posture with mandatory HTTPS, CSRF token usage, and integration of error monitoring via Bugsnag. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not evident, which could enhance protection against common web attacks. There is no visible security policy or incident response information publicly available, which could improve transparency and trust. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Compliance with GDPR is implied but not explicitly demonstrated through privacy or cookie policies. Incident response readiness and security culture indicators are not publicly visible, suggesting an opportunity for Airbnb to strengthen user trust through enhanced security disclosures.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add robust security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide visible contact information and procedures for security incident reporting and vulnerability disclosure.
  4. Enhance cookie consent mechanisms to comply with privacy regulations and improve user transparency.
  5. Regularly audit third-party scripts and tracking services to minimize privacy risks and improve performance.

Technical notes

Notes

The website leverages a modern technology stack centered on React and JavaScript, with advanced browser APIs like IntersectionObserver and PerformanceObserver for performance monitoring. The use of Bugsnag indicates proactive error tracking. The site is optimized for mobile devices and accessibility, with responsive design and semantic HTML elements. SEO is supported by comprehensive meta tags, Open Graph data, and structured JSON-LD for search engines. Hosting details are not explicitly identified, but the use of muscache.com domains suggests Airbnb's own infrastructure or CDN usage. Performance is fast with preloading of critical scripts and styles. Technical risks are minimal, though the absence of some security headers and privacy disclosures represents areas for improvement to reduce potential compliance and security risks.
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.
