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 maintains a dominant position in the vacation rental market through its platform business model, generating revenue via service fees from bookings. The company targets a broad audience of travelers and hosts, offering diverse accommodation types and experiences. Its global footprint is supported by numerous localized domains, including www.airbnb.gr for Greece. The business benefits from strong brand recognition, extensive partnerships, and a robust technological infrastructure. Growth indicators include continuous feature enhancements and expansion into new markets. The company also holds SOC 2 Type II certification, underscoring its operational security standards.

Security posture

The website demonstrates a high level of security maturity with enforced HTTPS, comprehensive security headers, and use of modern script isolation techniques. No vulnerabilities or exposed sensitive data were detected in the analysis. Privacy policies and cookie consent mechanisms align with GDPR requirements. However, the absence of a publicly visible incident response contact or security.txt file suggests room for improvement in transparency and vulnerability disclosure. Overall, Airbnb's security practices effectively mitigate common web threats and protect user data.

Recommendations

  1. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  2. Enhance visibility of incident response contacts for improved transparency.
  3. Regularly audit third-party scripts and dependencies to prevent vulnerabilities.
  4. Continue to monitor and update privacy and cookie consent mechanisms to comply with evolving regulations.
  5. Invest in user education and trust-building measures to reinforce security culture.

Technical notes

Notes

The website is built on a modern React-based frontend with advanced performance optimizations such as Partytown for third-party script management. It uses Google Tag Manager and Bugsnag for analytics and error monitoring. The site is hosted on a reliable cloud infrastructure, likely AWS, ensuring scalability and availability. SEO and accessibility best practices are implemented, including proper meta tags, language localization, and ARIA roles. The site loads quickly and is fully responsive, providing an excellent user experience across devices. Technical debt appears minimal, with a clean and maintainable codebase.
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.
