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

1 finding rated critical or high. Fix these first.

  1. 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

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

Strukton Rail holds a strong position in the Scandinavian railway infrastructure market as a large, established service provider. Their business model focuses on delivering comprehensive railway construction and maintenance services, targeting public sector clients and large infrastructure projects. The company leverages multilingual websites to serve different regional markets, indicating a broad geographic footprint. Their digital presence includes active social media channels and a dedicated job portal, supporting recruitment and brand engagement. The absence of direct contact emails or phone numbers on the main site suggests a controlled communication approach, likely funneling inquiries through contact forms. The company demonstrates commitment to sustainability and corporate responsibility, which aligns with their branding and market positioning.

Security posture

The website employs HTTPS with a valid SSL certificate, uses cookie consent management via Cookiebot, and integrates Google Tag Manager for analytics. However, no advanced security headers were detected in the HTML content, and there is no published security policy or incident response contact information. The lack of a vulnerability disclosure page or security.txt file indicates limited transparency in security practices. No exposed sensitive data or vulnerable libraries were found. Overall, the security posture is good but could be enhanced by implementing additional HTTP security headers, publishing security policies, and providing clear incident response channels.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  3. Publish a dedicated security policy page and provide incident response contact information to improve transparency and trust.
  4. Create and maintain a vulnerability disclosure or security.txt file to encourage responsible reporting of security issues.
  5. Regularly audit and update third-party plugins and scripts to minimize risks from vulnerable components.

Technical notes

Notes

The website is built on a modern WordPress platform with up-to-date plugins including Yoast SEO for search optimization and WP Rocket for caching and performance. The use of Cookiebot ensures compliance with cookie consent regulations. The site loads with moderate speed and is mobile optimized with responsive design. Accessibility features are basic but present. The hosting provider is not explicitly identified, but DNS is managed via Akamai name servers, suggesting a reliable CDN or hosting infrastructure. The site uses common JavaScript libraries such as jQuery and Slick Slider for UI components. Overall, the technical implementation is solid with opportunities for further optimization in accessibility and security headers.
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.
