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

Stena Line is a major ferry transportation company operating routes across the UK, Ireland, Holland, and Northern Europe. The website provides comprehensive information about ferry routes, onboard services, destinations, and special offers, targeting travelers and freight customers in Northern Europe. The company maintains a strong market position with a large-scale operation and a professional online presence. Technically, the website is built on Adobe Experience Manager, leveraging modern web technologies and third-party services for analytics, advertising, and personalization. Security measures include HTTPS, CAPTCHA protections, and cookie consent management, although explicit security headers could be improved. The absence of WHOIS data is a notable anomaly that slightly reduces domain trust but does not detract from the overall professionalism of the site. Privacy compliance is well addressed with GDPR-aligned policies and consent mechanisms. Overall, the site is reliable, user-friendly, and secure for its intended audience.

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

4 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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 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';…
  3. 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

Stena Line operates in the transportation sector, focusing on ferry services for passengers and freight. Its business model revolves around route-based ferry transport with online booking capabilities and loyalty programs. The company targets a broad audience including tourists, commuters, and commercial freight operators. The website reflects a mature digital strategy with integration of marketing and analytics tools, indicating a focus on customer engagement and data-driven decision making. Partnerships with API providers and booking platforms enhance service delivery. The lack of visible WHOIS data suggests either privacy protection or a recent domain registration, which is unusual for a company of this size and may warrant further verification.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and use of CAPTCHA services to mitigate automated abuse. Cookie consent is managed via OneTrust, supporting GDPR compliance. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not clearly present in the provided data, which could be improved to enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the analysis. The use of multiple third-party scripts requires ongoing monitoring to prevent supply chain risks. Incident response and security policy documentation are not publicly evident, suggesting an area for enhancement in transparency and readiness.

Recommendations

  1. Implement and verify comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish or make accessible a formal security policy and incident response plan to improve transparency and trust.
  3. Regularly audit third-party scripts and dependencies to mitigate supply chain vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Investigate and clarify WHOIS data availability to improve domain registration transparency and trust.

Technical notes

Notes

The website is built on Adobe Experience Manager, a robust enterprise CMS platform, indicating a high level of technical maturity. It uses modern JavaScript libraries and integrates multiple third-party services for analytics, advertising, and personalization. Performance is moderate with room for optimization, especially in script loading and CSS management. Mobile optimization is good, ensuring usability across devices. SEO practices are well implemented with proper meta tags and Open Graph data. Accessibility is basic and could be improved to meet higher standards. Hosting appears to leverage Cloudflare services, providing CDN and security benefits. 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.
