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

Airbnb is a leading global online marketplace specializing in vacation rentals, experiences, and related services. The platform connects travelers with hosts offering a wide range of accommodations worldwide, serving millions of users across more than 220 countries and regions. The website is professionally designed, mobile-optimized, and provides a seamless user experience with rich content and interactive search features. Technically, the site leverages modern web technologies including React, advanced JavaScript libraries, and performance optimization tools such as Partytown for script isolation. The hosting infrastructure appears robust, utilizing reputable CDNs and asset delivery networks. SEO and accessibility considerations are well implemented, contributing to fast load times and good user engagement. From a security perspective, the website enforces HTTPS and employs several best practices such as CSRF token usage and error reporting via Bugsnag. However, explicit security headers and public security policies are not evident in the provided data, indicating areas for improvement. Privacy compliance is basic, with no clear privacy or cookie policy links detected in the analyzed content. Overall, Airbnb.dk presents a trustworthy and professional online presence consistent with a large enterprise in the hospitality industry. The absence of WHOIS data limits domain registration verification, but the brand's global recognition and technical maturity mitigate concerns. Strategic recommendations include enhancing privacy disclosures, publishing security policies, and improving security header implementation to further strengthen trust and compliance.

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

3 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 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.

    • 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 facilitates peer-to-peer short-term lodging and experiences. Its competitive advantage lies in its extensive global reach, brand recognition, and diversified service offerings including homes, experiences, and services. Revenue streams primarily derive from booking fees and service charges. The target customer segments include leisure and business travelers seeking flexible and unique accommodation options. Growth indicators include continuous platform enhancements and expansion into new markets. The partnership ecosystem includes advertising and analytics providers such as Google and Bugsnag. Operationally, Airbnb maintains a high level of digital maturity with a focus on user experience and performance.

Security posture

The security posture of Airbnb.dk is solid with mandatory HTTPS enforcement and use of CSRF tokens to protect user sessions. The integration of error reporting tools like Bugsnag indicates proactive monitoring of client-side issues. The use of Partytown suggests an effort to isolate third-party scripts, reducing attack surface. However, the lack of visible security headers such as Content-Security-Policy and absence of publicly disclosed security or incident response policies represent gaps. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Compliance with GDPR is implied but not explicitly demonstrated through policy links or consent mechanisms. Incident response readiness and security culture indicators are not publicly visible, suggesting room for transparency improvements.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Provide publicly accessible security policy and incident response contact information to improve transparency and trust.
  4. Enhance cookie consent mechanisms to ensure explicit user consent and compliance with privacy regulations.
  5. Regularly audit WHOIS data and ensure domain registration information is accurate and publicly available where possible.

Technical notes

Notes

The website is built on a modern React framework with extensive use of JavaScript and CSS for dynamic content rendering and styling. Performance optimizations include script isolation via Partytown and preloading of critical assets. The site is mobile-optimized with responsive design and accessibility features such as skip links and ARIA attributes. SEO is supported by meta tags, Open Graph data, and structured JSON-LD for search actions. Hosting is likely via a robust CDN infrastructure (muscache.com). No CMS was explicitly detected, suggesting a custom or proprietary platform. The technical implementation reflects a mature, scalable, and user-centric architecture with minor opportunities for security header enhancements and privacy compliance improvements.
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.
