Airbnb is a leading global online marketplace specializing in vacation rentals, experiences, and hosting services. The platform connects travelers with hosts offering diverse accommodations worldwide, with a strong presence in Germany as evidenced by the localized German website. The business model is based on facilitating peer-to-peer short-term lodging and travel experiences, positioning Airbnb as a dominant player in the hospitality industry. The website demonstrates a mature digital infrastructure leveraging modern technologies such as React, Mapbox, and Google Tag Manager, ensuring a fast, responsive, and accessible user experience. Security practices include HTTPS enforcement and CSRF protections, though explicit security headers and policies are not visible in the provided content. Privacy compliance indicators such as privacy and cookie policies are not detected in the analyzed HTML, which may impact compliance posture. Overall, the domain registration and DNS configurations align with Airbnb's enterprise-grade infrastructure, supporting the legitimacy and trustworthiness of the platform.

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 as an essential entity in the hospitality sector, targeting global travelers and hosts. Its competitive advantage lies in its extensive inventory of over seven million listings and a broad geographic footprint spanning more than 220 countries and regions. Revenue streams primarily include service fees from bookings and hosting. The platform's partnership ecosystem includes integrations with mapping services and analytics providers. The German localized site indicates a tailored approach to regional markets, enhancing user engagement and market penetration. Strategic observations highlight Airbnb's focus on user experience, technological innovation, and brand consistency to maintain market leadership.

Security posture

The website exhibits a good security maturity level with HTTPS enforced and CSRF tokens implemented. However, the absence of explicit security headers such as HSTS, X-Content-Type-Options, and X-Frame-Options in the provided content suggests room for improvement. No vulnerabilities or exposed sensitive data were detected. The lack of a visible security policy or incident response contact channels limits transparency and may affect user trust. Compliance with GDPR is implied by the regional focus but not explicitly confirmed through policy documents. Incident response readiness and security culture indicators are not discernible from the content. Overall, the security posture is solid but could benefit from enhanced transparency and additional security controls.

Recommendations

  1. Publish and prominently link comprehensive privacy and cookie policies to improve privacy compliance and user trust.
  2. Implement and advertise a formal security policy and incident response contact channels to enhance transparency and readiness.
  3. Add standard security headers (HSTS, X-Content-Type-Options, X-Frame-Options) to strengthen defense-in-depth.
  4. Provide clear contact information including verified company emails and phone numbers to improve business credibility.
  5. Regularly audit and update third-party scripts and tracking tools to minimize potential vulnerabilities and privacy risks.

Technical notes

Notes

The website is built on a modern React framework (version 18.3.1) with extensive use of asynchronous JavaScript loading and CSS variables for styling. It integrates multiple third-party services including Google Tag Manager for analytics and Mapbox for mapping functionalities. Hosting is managed via AWS infrastructure, indicated by the DNS configuration. Performance optimizations such as lazy loading, video format fallbacks, and intersection observers are employed to enhance user experience. Accessibility features like skip links and ARIA roles are present, supporting inclusive design. SEO is supported by comprehensive meta tags, Open Graph data, and JSON-LD structured data. The technical implementation reflects a high level of digital maturity suitable for an enterprise-level hospitality platform.
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.
