SJ.se is the official website of SJ, the leading Swedish rail operator offering train ticket booking and travel information services primarily for travel within Sweden and to nearby international destinations such as Copenhagen and Oslo. The website targets both domestic and international travelers seeking convenient rail travel options. The business model centers on ticket sales and travel-related services, positioning SJ as a key player in Sweden's transportation sector. Technically, the website employs a modern React-based frontend with integrations including Adobe Launch for tag management, Microsoft AppInsights for monitoring, and Queue-Fair for traffic management. The site demonstrates good mobile optimization, accessibility, and SEO practices, providing a smooth user experience. External resources are loaded from trusted domains, and the site uses HTTPS with a good SSL configuration. From a security perspective, SJ.se enforces HTTPS and employs cookie consent mechanisms aligned with GDPR requirements. While explicit security headers and incident response policies are not directly visible in the HTML, the site shows no signs of exposed sensitive data or vulnerable libraries. Tracking technologies include Adobe Analytics and Facebook Pixel, with moderate user tracking levels balanced by privacy compliance measures. Overall, SJ.se presents a professional, trustworthy, and well-maintained digital presence consistent with a large transportation enterprise. Recommendations include publishing explicit security policies, incident response contacts, and vulnerability disclosure information to further enhance transparency and security posture.

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

7 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

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

SJ operates as Sweden's primary rail transport provider, leveraging a strong brand and extensive network coverage. The company benefits from a large customer base including daily commuters and leisure travelers. Revenue streams are primarily from ticket sales, supplemented by loyalty programs (SJ Prio) and partnerships with hospitality providers. The website reflects a mature digital ecosystem with integrations for marketing, analytics, and customer engagement. SJ's market position is reinforced by consistent branding and comprehensive travel offerings. The absence of direct contact information on the homepage suggests a focus on digital self-service. Strategic growth may involve expanding digital services and enhancing customer support channels.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS and cookie consent aligned with GDPR. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of visible security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. The use of modern frameworks and absence of outdated libraries reduce risk exposure. Tracking technologies are present but balanced with user privacy controls. Overall, SJ.se maintains a good security posture appropriate for a large public-facing transportation service but should enhance policy disclosures and incident management visibility.

Recommendations

  1. Publish a dedicated security policy page detailing security frameworks and practices.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file.
  4. Enhance transparency around data protection officer contact information and GDPR compliance.
  5. Regularly audit and publish security headers and SSL/TLS configurations to maintain best practices.

Technical notes

Notes

SJ.se uses a modern React-based frontend with module preloading and integration of multiple third-party services including Adobe Launch for tag management and Microsoft AppInsights for telemetry. The site is optimized for mobile devices and accessibility, with responsive images and ARIA attributes. Performance is moderate, with some reliance on external CDNs and queue management services to handle traffic spikes. The absence of a detected CMS suggests a custom or proprietary platform. Technical risks are low, but continuous monitoring of third-party dependencies and security headers is recommended to mitigate emerging threats.
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.
