Airbnb is a leading global online marketplace specializing in vacation rentals, experiences, and related services. The platform connects travelers with hosts offering a wide range of accommodations worldwide, supporting over 7 million listings across more than 220 countries and regions. The website is professionally designed, multilingual, and optimized for mobile devices, reflecting a mature digital infrastructure. Technically, Airbnb employs modern web technologies including React and advanced performance monitoring tools such as Bugsnag. The security posture is strong with HTTPS enforced and CSRF protections indicated, though explicit security headers could be improved. Privacy compliance indicators such as privacy and cookie policies were not found in the provided HTML snippet, suggesting room for enhancement in transparency and GDPR adherence. Overall, Airbnb's website demonstrates high business credibility and user trust, with extensive content and clear navigation. The absence of WHOIS data limits domain legitimacy verification, but the brand presence and content quality strongly support its authenticity.

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.

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 operates in the hospitality sector as an essential enterprise-level business with a robust global market position. Its business model is based on an online marketplace facilitating peer-to-peer vacation rentals and experiences. The platform targets travelers and hosts worldwide, leveraging a large inventory and traveler recommendations as trust signals. Revenue streams likely include booking fees and service charges. The company maintains a consistent brand identity and offers services in multiple languages, indicating a broad international reach. While no direct contact or corporate registration details were found, the website's professional quality and extensive service offerings reflect a mature and well-established operation.

Security posture

The website enforces HTTPS and uses security best practices such as CSRF token meta tags and error monitoring via Bugsnag. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not evident in the provided data, which could enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy policies and incident response contacts were not found, indicating potential compliance gaps with GDPR and other regulations. The security score is good but could be improved with more comprehensive security headers and clearer privacy disclosures.

Recommendations

  1. Implement and enforce comprehensive security headers including Content-Security-Policy and X-Frame-Options.
  2. Publish clear and accessible privacy and cookie policies with explicit GDPR compliance statements.
  3. Provide visible contact information for security incidents and data protection officer details.
  4. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance transparency around data collection, retention policies, and user consent mechanisms.

Technical notes

Notes

Airbnb's website uses a modern React-based frontend with extensive use of JavaScript and CSS optimizations. It leverages performance monitoring tools such as Bugsnag and Google Tag Manager for analytics and error tracking. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured data (JSON-LD). Hosting details and CMS are not explicitly identified, but the use of muscache.com domains suggests proprietary infrastructure. Performance is moderate with preloading of critical scripts and styles. Opportunities exist to improve technical SEO and security header implementation to reduce technical 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.
