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 holds a dominant position in the hospitality sector, particularly in short-term vacation rentals and experiences. Its business model is a marketplace platform generating revenue through service fees from hosts and guests. The company targets global travelers and hosts, offering a wide range of accommodations and experiences. The Dutch localized site supports Airbnb's global expansion and market penetration strategy. Partnerships with mapping providers and analytics services enhance platform capabilities. The absence of direct contact emails or phone numbers on the homepage suggests a focus on digital self-service and support via help center forms. The brand is consistent and trusted, supported by extensive content and social media presence.

Security posture

The website exhibits a strong security posture with enforced HTTPS, modern security headers, and CSRF protections. Use of third-party services like Bugsnag for error reporting indicates proactive monitoring. However, there is no public disclosure of security policies, incident response plans, or vulnerability disclosure programs, which could enhance transparency and trust. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The security score is high but could be improved by publishing formal security documentation and response contacts.

Recommendations

  1. Publish a dedicated security policy and incident response plan accessible to users.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clearer company contact information for security and abuse reporting.
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance transparency on data retention and processing practices to strengthen privacy compliance.

Technical notes

Notes

The website is built on a modern React framework with extensive use of asynchronous JavaScript modules and third-party APIs such as Google Maps and Mapbox. Performance optimizations include lazy loading, intersection observers, and prefetching strategies. Accessibility features like skip links and ARIA roles are implemented, supporting inclusive design. The site is mobile-optimized with responsive layouts and touch-friendly controls. SEO is supported by comprehensive meta tags, Open Graph data, and structured JSON-LD. Hosting details are not explicit but likely involve major cloud providers. Overall, the technical infrastructure is robust, scalable, and aligned with best practices for a global enterprise 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.
