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

6 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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 real estate and hospitality sectors, connecting hosts with guests seeking short-term accommodations globally. Its business model is platform-based, generating revenue through service fees on bookings. The company targets a broad audience of travelers, offering diverse lodging options and experiences. The website's extensive listings, high-quality content, and global reach underscore its market leadership. Strategic partnerships and a comprehensive technology stack support its operations. The absence of direct contact details and explicit policy documents in the content suggests reliance on user account systems and centralized support channels.

Security posture

The website employs strong security practices including HTTPS encryption, use of security headers, and integration of error monitoring tools like Bugsnag. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the lack of visible security policies or incident response contacts may limit user awareness of security measures and reporting channels. The site appears well-protected against common web threats, but could benefit from publishing clear security and incident response information to enhance transparency and trust.

Recommendations

  1. Publish comprehensive and easily accessible privacy and cookie policies on the website.
  2. Implement and publicize a vulnerability disclosure policy and security incident response contacts.
  3. Provide clear and verified contact information for business and security inquiries.
  4. Enhance accessibility features to meet higher standards and improve user experience for all users.
  5. Regularly review and update third-party scripts and dependencies to mitigate potential vulnerabilities.

Airbnb's website is built on a modern React framework with extensive use of JavaScript libraries and APIs such as Google Maps and Mapbox for geolocation services. The site is hosted on Akamai CDN, ensuring fast content delivery globally. Performance optimizations include preloading critical resources and using advanced browser APIs for user interaction metrics. The site is mobile-optimized with responsive design and accessibility considerations. Technical debt appears minimal, with ongoing feature flagging and experimentation indicating active development and modernization efforts.
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.
