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. 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

      • 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

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's business model centers on an online marketplace facilitating peer-to-peer short-term rentals and experiences. Revenue streams include service fees from bookings and hosts. The company targets travelers seeking diverse and flexible accommodation options and hosts looking to monetize their properties. Strategic partnerships and a broad global footprint enhance its competitive advantage. The platform's extensive content and user engagement indicate strong growth and market penetration. Airbnb maintains a consistent brand identity and leverages certifications such as SOC 2 and ISO 27001 to reinforce trust. The absence of direct contact emails or phone numbers on the homepage suggests a focus on digital self-service and support channels.

Security posture

The website exhibits a mature security posture with enforced HTTPS, multiple security headers, and secure form handling practices. Use of CSRF tokens and content security policies mitigate common web vulnerabilities. Error reporting integration with Bugsnag enables proactive monitoring of client-side issues. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the lack of publicly visible incident response or security policy pages indicates an opportunity for improved transparency. Compliance with GDPR is evident through privacy and cookie policies with consent mechanisms. Overall, Airbnb demonstrates strong security controls appropriate for its business scale and regulatory environment.

Recommendations

  1. Enhance public visibility of incident response and security policies to improve transparency and user trust.
  2. Maintain continuous dependency and vulnerability management to prevent introduction of insecure libraries.
  3. Implement and publicize a formal vulnerability disclosure program with security.txt to encourage responsible reporting.
  4. Expand contact information availability for security and privacy inquiries to facilitate communication.
  5. Regularly review and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

Airbnb's website is built on a modern React-based frontend with extensive use of asynchronous JavaScript and CSS modules. The site is optimized for fast loading and mobile responsiveness, with preloading of critical scripts and assets. Integration with Google Tag Manager and Bugsnag supports analytics and error monitoring. The hosting environment is likely Amazon AWS, inferred from asset domains. Accessibility features such as skip links and screen reader support are present, contributing to a good user experience. SEO is well implemented with comprehensive meta tags, Open Graph data, and structured JSON-LD schema. The technical infrastructure supports a scalable, secure, and user-friendly platform aligned with enterprise standards.
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.
