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

Airbnb.dk is the Danish localized website of Airbnb, Inc., a global leader in the hospitality and vacation rental industry. The platform offers millions of vacation homes, cabins, and beach houses across more than 220 countries and regions worldwide. The website is professionally designed, highly accessible, and optimized for mobile devices, providing a seamless user experience for travelers and hosts alike. The business model centers on an online marketplace connecting hosts with guests, facilitating short-term rentals and experiences. Airbnb holds a strong market position as a trusted and innovative platform in the hospitality sector. Technically, the website leverages modern web technologies including React 18, Google Tag Manager, and Partytown for script management, alongside map services like Mapbox and Google Maps API. The infrastructure supports fast loading times, good SEO practices, and accessibility features, reflecting a mature digital presence. The site employs robust security measures such as HTTPS, Content Security Policy, and consent-based tracking mechanisms, ensuring user data protection and compliance with GDPR. Security posture is strong with no evident vulnerabilities or exposed sensitive information. However, explicit security policies and incident response contacts are not publicly detailed, representing an area for improvement. Privacy and cookie policies are comprehensive and clearly communicated, supporting regulatory compliance. Overall, Airbnb.dk demonstrates a high level of business credibility, technical sophistication, and user trustworthiness. The risk assessment is low given the brand's global reputation and secure web practices. Strategic recommendations include publishing detailed security policies, establishing a vulnerability disclosure program, and enhancing incident response transparency 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.

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 global online marketplace for lodging and tourism experiences, targeting travelers and hosts worldwide. The company benefits from a strong brand, extensive global reach, and a diversified service offering including home rentals and experiences. Revenue streams primarily come from service fees charged to guests and hosts. The platform's competitive advantage lies in its vast inventory, user-friendly interface, and community trust mechanisms. Airbnb's partnership ecosystem includes technology providers and localized domains to support regional markets. Growth indicators include continuous feature innovation and expansion into new markets. The Danish site reflects localization efforts to cater to regional users, enhancing market penetration and customer engagement.

Security posture

The website exhibits a mature security posture with enforced HTTPS, use of Content Security Policy via Partytown, and secure cookie consent mechanisms. No exposed credentials or sensitive data were detected in the HTML content. The absence of explicit security policy pages and incident response contacts suggests room for improvement in transparency and preparedness. Compliance with GDPR is evident through privacy and cookie policies. No known vulnerabilities or outdated libraries were identified. The security culture appears proactive but could benefit from formalized vulnerability disclosure and incident response documentation to align with best practices.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and user protections.
  2. Establish and publicize a vulnerability disclosure program to encourage responsible reporting.
  3. Provide clear incident response contact information to enhance transparency and trust.
  4. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  5. Enhance user education on privacy and security features through accessible resources.

Technical notes

Notes

Airbnb.dk is built on a modern React framework with extensive use of asynchronous script loading and advanced client-side technologies such as Partytown for third-party script management. The site integrates multiple map services and analytics tools, ensuring rich functionality and data-driven insights. Performance is optimized with deferred script loading and CSS management. Accessibility considerations are evident, including screen reader support and keyboard navigation aids. SEO is enhanced through structured data (JSON-LD) and comprehensive meta tags. The technical infrastructure reflects a scalable, maintainable, and user-centric design, supporting a global enterprise-level platform.
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.
