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

Strukton Infraspecials is a Dutch infrastructure company specializing in sustainable and innovative civil engineering projects including tunnels, water construction, and rail-civil works. The company positions itself as a reliable partner focused on safety, sustainability, and collaboration, targeting business and government clients in the transportation and energy sectors. The website is professionally designed, well-structured, and optimized for SEO and mobile devices, reflecting a mature digital presence despite the domain's recent registration in early 2024. Technically, the site uses WordPress with modern plugins and scripts, hosted by LeaseWeb Netherlands with DNSSEC enabled and HTTPS enforced, indicating a strong security baseline. However, explicit security policies and incident response information are not published, representing an area for improvement. Privacy compliance is well addressed with clear privacy and cookie policies and a consent mechanism. Overall, the site demonstrates a solid business credibility and trustworthy online presence.

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

2 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

  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.

    • 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

The company operates in the infrastructure and civil engineering market in the Netherlands, leveraging its parent company Strukton's brand and network. Its business model is B2B, providing comprehensive infrastructure solutions with a focus on lifecycle management and innovation. The website links to partner and recruitment domains, indicating a broad ecosystem and growth orientation. The content emphasizes safety, sustainability, and innovation as competitive advantages. The recent domain registration aligns with a possible rebranding or new digital initiative. The company targets government and large enterprise clients, positioning itself as a key player in Dutch infrastructure development.

Security posture

The website enforces HTTPS with a valid SSL certificate and DNSSEC, uses cookie consent management, and integrates Google Tag Manager for analytics. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure reduces transparency and may impact trust for security-conscious stakeholders. The site could benefit from additional security headers and a security.txt file to improve its security posture and incident readiness. Overall, the security maturity is good but not comprehensive.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance.
  2. Add incident response contact information and consider a vulnerability disclosure policy or security.txt file.
  3. Implement additional HTTP security headers such as Content-Security-Policy and X-Content-Type-Options.
  4. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.
  5. Enhance transparency by publishing data protection officer contact details and data retention policies.

The technical stack is modern and well maintained, supporting a professional user experience and strong SEO performance.
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.
