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

10 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

      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

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 an enterprise-scale business model as a marketplace connecting hosts and guests worldwide. Its competitive advantage lies in its extensive global reach, diverse accommodation offerings, and integrated experiences. Revenue streams include service fees from bookings and experiences. The platform targets a broad customer segment ranging from leisure travelers to business users. Growth indicators include continuous expansion into new markets and services. The partnership ecosystem includes regional domains and integrations with payment processors and analytics providers. Strategic observations highlight Airbnb's focus on user trust, platform security, and regulatory compliance to sustain its market leadership.

Security posture

The website exhibits a high level of security maturity with enforced HTTPS, strong content security policies, and use of modern security best practices such as script offloading and service workers. No exposed sensitive data or vulnerable libraries were identified in the analyzed content. Privacy policies and cookie consent mechanisms are comprehensive and GDPR compliant. However, no explicit public security policy or incident response information was found, which could be improved to enhance transparency. The absence of a vulnerability disclosure program or security.txt file suggests an opportunity to formalize external security communications. Overall, Airbnb maintains a secure environment suitable for handling sensitive user data and transactions.

Recommendations

  1. Implement and publicize a formal vulnerability disclosure program and security.txt file to encourage responsible reporting.
  2. Publish a detailed security policy and incident response plan accessible to users and partners.
  3. Regularly audit and update third-party scripts and dependencies to mitigate emerging vulnerabilities.
  4. Enhance contact information availability for security and privacy inquiries to improve transparency.
  5. Continue investing in privacy compliance and user data protection to maintain regulatory alignment.

Technical notes

Notes

The website is built on a modern React framework with extensive use of JavaScript and CSS optimizations. It employs Partytown for offloading third-party scripts to improve performance and reduce main thread blocking. Hosting is likely on Amazon AWS infrastructure, supported by a global CDN (muscache.com). Performance is optimized with preloading of critical scripts and responsive design for mobile devices. Accessibility features such as skip links and ARIA labels are present, contributing to a good user experience. SEO is supported by comprehensive meta tags, Open Graph data, and structured JSON-LD markup. Technical risks are minimal but include the need for continuous monitoring of third-party scripts and dependencies.
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.
