Airbnb, Inc. · Hospitality · Netherlands

Medium risk. 9 critical or high findings in GDPR outside view, Security headers and 1 other check.

Security score

58/100

Risk levelMedium

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

The website www.airbnb.nl is currently inaccessible due to a security mechanism or Web Application Firewall (WAF) blocking access, as evidenced by the 'Access Denied' page and reference to errors.edgesuite.net. This prevents extraction of any meaningful content, metadata, or business information from the site itself. The domain WHOIS data is structured and consistent with Airbnb, Inc., a large enterprise in the hospitality sector operating globally, including the Netherlands. Due to the access block, no privacy, cookie, or terms of service policies could be verified, nor any contact or security policy information. The lack of accessible content severely limits the ability to assess technical infrastructure, security posture, or compliance status. The site appears to be protected by a generic WAF or security service, which is likely intentional to prevent unauthorized access or scraping.

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

9 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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, Inc. is a well-known global enterprise in the hospitality industry, providing an online marketplace for lodging and tourism experiences. The .nl domain indicates a localized presence in the Netherlands. The business model revolves around peer-to-peer property rental services. The WHOIS data aligns with the expected registrant information for Airbnb, supporting legitimacy. However, no direct business content or contact information was accessible on the site to further analyze market positioning, partnerships, or growth indicators. The domain age and registration details are consistent with a mature, established business.

Security posture

Due to the access denial, no direct security headers, SSL configuration, or vulnerability information could be assessed. The presence of a WAF or security block suggests a proactive security posture to protect the site from unauthorized access or attacks. However, the lack of accessible security or incident response policies limits visibility into compliance with GDPR or other frameworks. No exposed sensitive data or vulnerabilities were detected from the provided content. Overall, the security posture appears cautious but cannot be fully evaluated.

Recommendations

  1. Resolve access issues to allow legitimate users and security analysts to access the site content for comprehensive evaluation.
  2. Publish and make accessible privacy, cookie, and terms of service policies to improve transparency and compliance.
  3. Implement visible contact and incident response information to enhance trust and facilitate security communication.
  4. Ensure security headers and HTTPS configurations are properly implemented and verifiable.
  5. Consider providing a security.txt or vulnerability disclosure policy to encourage responsible reporting.
Site observations

Automated reading of the public site. Ratings are indicative.

Generic detected. Access Denied page with minimal HTML content and reference to errors.edgesuite.net indicates a WAF or security mechanism blocking access. These observations may be incomplete. For a fuller analysis, contact guard@offseq.com.

Key observations

  1. Website content is inaccessible due to a WAF or security block.
  2. No metadata, forms, scripts, or business content available for analysis.
  3. WHOIS data is structured and consistent with a legitimate enterprise.
  4. No contact or policy information is extractable from the provided content.
  5. Analysis is limited due to access denial; further investigation requires access clearance.
Technical notes

Notes

No technical details about the website's infrastructure, CMS, frameworks, or performance could be extracted due to the access denial. The minimal HTML content indicates a security block rather than a functional website page. The reference to errors.edgesuite.net suggests use of a CDN or security service that enforces access restrictions. Without access, no assessment of technical debt, modernization opportunities, or risks is possible.
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.
