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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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';…

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

Westin's market positioning as a premium wellness-focused hospitality brand is reinforced by its extensive global footprint and integration within the Marriott Bonvoy loyalty ecosystem. The business model centers on providing luxury accommodations with wellness-centric services, including spas, fitness, and healthy dining options. The website's partnership ecosystem includes multiple Marriott sister brands and dedicated merchandise stores, indicating a broad and cohesive brand strategy. Growth indicators include recent hotel openings and continuous content updates.

Security posture

The website employs HTTPS with strong SSL configuration and implements standard security best practices such as consent management via OneTrust and use of secure forms. Multiple security headers are likely in place, although not explicitly visible in the HTML. No critical vulnerabilities or exposed sensitive data were detected. However, the site lacks explicit security policy pages, incident response contacts, and vulnerability disclosure mechanisms, which are recommended for enhanced transparency and readiness.

Recommendations

  1. Publish a dedicated security policy and incident response information page to improve transparency.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance visible security headers and provide security-related metadata for improved trust signals.
  5. Provide direct security contact channels (e.g., security@ or abuse@ email addresses) for incident reporting.

Notes

The website is built on WordPress with WPML for multilingual support, leveraging modern JavaScript libraries and frameworks such as VideoJS and Brightcove for media delivery. It integrates extensive analytics and marketing tools including Adobe Launch, Google Tag Manager, and multiple tracking pixels. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate, with potential for optimization in script loading and resource management. The technical infrastructure reflects a mature, enterprise-grade platform consistent with a global hospitality brand.
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.
