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

    • 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

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

    • 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';…

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 holds a dominant position in industrial construction and food sectors in Belgium and surrounding regions. Their diversified subsidiaries cover multiple specialized domains, enhancing market reach and resilience. The business model leverages sustainability certifications as a competitive advantage and aligns with growing ESG demands. The presence of a dedicated recruitment site and regional social projects indicates a mature organizational structure with community engagement. The extensive network of related domains confirms a broad operational footprint. Growth indicators include ongoing sustainability certifications and electrification of their vehicle fleet. Strategic partnerships and social sustainability projects further strengthen their ecosystem.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and cookie consent implemented. However, no explicit security headers were detected in the provided data, and no incident response or vulnerability disclosure information is publicly available. The absence of a security.txt file or dedicated security contact reduces transparency in incident handling. No vulnerabilities or exposed sensitive data were found in the HTML content. The use of third-party scripts like Google Analytics is minimal and privacy-conscious. Overall, the security posture is adequate for a corporate website but could benefit from enhanced security headers, documented incident response, and regular security audits.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a security policy and incident response contact information to improve transparency and trust.
  3. Conduct regular security audits of third-party scripts and dependencies to mitigate vulnerabilities.
  4. Enhance accessibility features to meet WCAG standards and improve user experience for all visitors.
  5. Maintain up-to-date SSL/TLS configurations and monitor certificate validity to ensure secure communications.

Technical notes

Notes

The website uses standard HTML5, CSS3, and JavaScript with libraries such as Font Awesome and Plyr for media playback. The site is mobile responsive and includes SEO meta tags, although some meta descriptions are empty. Performance is moderate with some external font preloading. The site lacks a detected CMS, suggesting a custom or static site build. Hosting provider details are not evident from the HTML. Navigation is clear with multi-language support and structured menus. Cookie consent is implemented with granular control. Overall, the technical infrastructure is solid but could be enhanced with improved SEO metadata, 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.
