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. 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 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';…
  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

The company operates in the luxury real estate rental market, focusing on short term lets and vacation homes primarily in the UK, France, and the USA. Its business model combines direct rental bookings with a fully managed service for homeowners, indicating multiple revenue streams from both guests and property owners. The presence of an earnings calculator and partner programs suggests active homeowner acquisition and partnership strategies. The company benefits from strong brand recognition, industry awards, and a parent group affiliation, which supports its market credibility and growth potential. The target customer segment is affluent travelers and property owners seeking premium services. The website's integration with marketing and analytics tools indicates a data-driven approach to customer acquisition and retention.

Security posture

The website employs HTTPS with a valid SSL certificate and uses a consent management platform to comply with privacy regulations. Multiple third-party scripts for analytics and marketing are present, but no exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit security headers such as Content Security Policy (CSP), HSTS, or X-Frame-Options were not identified, which could enhance protection against common web attacks. There is no publicly available security policy or incident response information, and no vulnerability disclosure or security.txt file was found. Overall, the security posture is good but could be improved by implementing additional HTTP security headers and publishing formal security policies.

Recommendations

  1. Implement and verify HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures to improve transparency and trust.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerable components are included and minimize attack surface.
  5. Enhance accessibility features and provide more detailed data retention policies to improve compliance and user trust.

Technical notes

Notes

The website is built using modern web technologies including Vue.js for frontend interactivity, Stripe for payment processing, Google Maps API for location services, and HubSpot for marketing automation. Hosting is inferred to be on Amazon AWS based on DNS servers. The site includes multiple tracking and advertising scripts such as Adform, Facebook Pixel, Microsoft Clarity, and Sojern, integrated with a consent management platform (CookieFirst) to manage user privacy preferences. Performance is moderate with deferred and async script loading, and mobile optimization is good. SEO is supported by proper meta tags and structured content. There is room for improvement in accessibility and security header implementation. Overall, the technical infrastructure supports a professional and scalable online presence.
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.
