0–100, higher is better. How it is calculated

Airbnb is a leading global online marketplace specializing in vacation home rentals, experiences, and related services. The website targets travelers and hosts worldwide, offering a platform with millions of listings across over 220 countries and regions. The brand is well-established and recognized in the hospitality industry, operating at an enterprise scale with a consistent and professional online presence. Technically, the website employs modern web technologies including React, Partytown for script management, and Google Tag Manager for analytics and marketing. The site is optimized for performance and mobile responsiveness, with good accessibility and SEO practices. Hosting details are not explicitly stated but are consistent with large-scale cloud providers. Security-wise, the site enforces HTTPS and uses error reporting and script proxying to enhance security. However, explicit security headers and vulnerability disclosure mechanisms are not evident in the provided content. Privacy compliance indicators such as visible privacy and cookie policies are missing in the analyzed HTML snippet, which impacts the privacy compliance score. Overall, the website is trustworthy and professional, with strong business credibility and technical maturity. The lack of publicly available WHOIS data is likely due to privacy protection, which is justified for a business of this nature. Strategic improvements include enhancing privacy transparency, publishing security policies, and adding incident response contacts.

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

5 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.

    • 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 a dominant player in the hospitality sector, leveraging a marketplace business model that connects hosts with travelers seeking short-term accommodations and experiences. Its competitive advantage lies in its extensive global reach, brand recognition, and diversified service offerings including homes, experiences, and concierge services. Revenue streams primarily come from service fees charged to both guests and hosts. The platform targets a broad customer base ranging from leisure travelers to business travelers and hosts seeking to monetize their properties. Growth indicators include continuous expansion of listings and new service categories. The partnership ecosystem includes payment processors and marketing platforms, though specific partners are not detailed in the provided data.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and use of script proxying to mitigate third-party script risks. Error monitoring via Bugsnag indicates proactive incident detection. However, the absence of explicit security headers and lack of published security or incident response policies represent gaps in transparency and defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Compliance with GDPR and other privacy regulations is unclear due to missing policy disclosures. The security culture appears focused on operational monitoring but could benefit from enhanced user-facing security communications and formal vulnerability disclosure channels.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with clear consent mechanisms to improve GDPR compliance.
  2. Add standard security headers such as HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  3. Publish a security.txt file and incident response contact information to facilitate vulnerability reporting and improve transparency.
  4. Enhance visibility of contact information for privacy and security inquiries to build user trust.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Technical notes

Notes

The website is built on a modern React framework with advanced script management using Partytown to offload third-party scripts, improving performance and security. Google Tag Manager is used for analytics and marketing, integrated with consent management defaults. The site uses responsive design, CSS variables, and optimized media assets for fast loading and excellent mobile experience. Accessibility features such as skip links and ARIA roles are implemented. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting details are not explicit but inferred to be enterprise-grade cloud infrastructure. Technical risks include reliance on third-party scripts and lack of visible security headers.
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.
