Risk levelLow

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

Silversea Cruises operates as a premium luxury cruise line offering all-inclusive travel experiences to discerning travelers worldwide. The company markets itself as a provider of extraordinary voyages to over 900 destinations on 12 luxury ships, emphasizing discovery and exclusivity. The website reflects a strong market position in the luxury hospitality and transportation sectors, targeting affluent customers seeking high-end cruise vacations. Technically, the website is built on modern frameworks such as Gatsby and React, ensuring fast performance, mobile responsiveness, and good SEO practices. The site employs HTTPS with strong security headers, indicating a mature digital infrastructure. Privacy and cookie policies are comprehensive and GDPR compliant, supporting good privacy practices. From a security perspective, the site demonstrates solid best practices with no visible vulnerabilities or exposed sensitive data. However, the absence of WHOIS domain registration data raises concerns about domain transparency and ownership verification. No explicit security policy or incident response information is published, which could be improved to enhance trust. Overall, Silversea's website is professional, secure, and user-friendly, supporting its luxury brand image. The main risk lies in the lack of publicly available domain registration details, which should be addressed to improve legitimacy and trustworthiness. Strategic recommendations include publishing a security policy, incident response contacts, and verifying domain registration information.

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 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • 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

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

Silversea Cruises holds a strong position in the luxury cruise market, offering all-inclusive voyages to a global clientele. Their business model focuses on premium experiences with a fleet of 12 ships covering over 900 destinations, appealing to affluent travelers. The company likely generates revenue through direct bookings, partnerships, and travel agencies. The website's comprehensive content and branding consistency support a high level of professionalism and market credibility. Social media presence across major platforms enhances customer engagement and brand visibility. The lack of detailed corporate data such as founding year or parent company limits deeper business intelligence but does not detract from the evident market stature.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented, including HSTS, CSP, and X-Frame-Options. No sensitive information is exposed in the HTML content, and forms appear to be securely implemented. However, the absence of a publicly available security policy or incident response contact reduces transparency and preparedness perception. The missing WHOIS data is a notable gap in domain trustworthiness. There are no signs of malware, phishing, or vulnerabilities in the scanned content. Compliance with GDPR is indicated by privacy and cookie policies. Overall, the security posture is strong but could benefit from enhanced transparency and published security governance documents.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact information to improve transparency and readiness.
  3. Verify and update WHOIS domain registration details to ensure domain ownership transparency.
  4. Consider implementing and publishing a vulnerability disclosure policy or security.txt file.
  5. Enhance trust signals by adding certifications or third-party security attestations on the website.

Technical notes

Notes

The website leverages a modern technology stack centered on Gatsby and React, enabling fast loading times and excellent mobile responsiveness. The use of CSS modules and structured components indicates good front-end engineering practices. SEO is supported by comprehensive meta tags and Open Graph data. Accessibility features are present but could be further enhanced with ARIA roles and landmarks. Hosting details are not explicitly identified but performance metrics suggest a reliable hosting environment. No legacy or vulnerable libraries were detected. The site architecture supports scalability and maintainability, positioning the company well for future digital growth.
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.
