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.

    • 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

    • 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

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 hospitality and real estate sectors, leveraging a peer-to-peer business model that facilitates short-term rentals and experiences. Its competitive advantages include a vast global network, strong brand recognition, and diversified service offerings including experiences and hosting tools. Revenue streams primarily come from service fees charged to guests and hosts. The target customer segments include leisure and business travelers seeking alternative accommodations and unique local experiences. Growth indicators are positive, with continuous expansion into new markets and service verticals. The company maintains a broad partnership ecosystem, including payment processors and technology providers, to support its platform operations. Strategic observations highlight Airbnb's focus on user trust, platform safety, and regulatory compliance as key to sustaining market leadership.

Security posture

Airbnb exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and secure handling of user inputs and forms. The presence of monitoring tools such as Bugsnag indicates active error tracking and incident management. However, the absence of publicly accessible detailed security policies, incident response contacts, or vulnerability disclosure programs suggests areas for improvement in transparency and community engagement. Compliance with GDPR is evident through privacy policies and cookie consent mechanisms. No critical vulnerabilities or exposed sensitive data were detected in the website content. The security culture appears proactive but could benefit from enhanced public communication of security frameworks and certifications.

Recommendations

  1. Publish a detailed security policy and incident response plan accessible to users and security researchers.
  2. Implement and publicize a formal vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Regularly audit and update third-party libraries and dependencies to mitigate potential vulnerabilities.
  4. Enhance transparency around data protection officer contact information and compliance certifications.
  5. Continue investing in user education and trust-building measures to maintain high security and privacy standards.

Hosting and content delivery are managed via specialized domains for static assets, indicating a scalable and robust infrastructure. The site demonstrates excellent mobile optimization and accessibility features, contributing to a high-quality user experience. Technical risks are minimal, with no visible outdated components or performance bottlenecks.
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.
