Risk levelLow

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

BESIX is a well-established international construction and concessions group with a history dating back to 1909. The company offers a broad range of services across multiple sectors including buildings, infrastructure, marine works, environment, and real estate. The website reflects a mature enterprise with a strong market position and a diversified portfolio of subsidiaries. Technically, the site uses modern frameworks such as Next.js and Storyblok CMS, with good mobile optimization and accessibility. Security posture is solid with HTTPS and cookie consent mechanisms, though explicit security headers and incident response information are absent. The lack of WHOIS data introduces a minor trust concern but does not detract significantly from the overall legitimacy. Strategic recommendations include enhancing security headers, publishing security policies, and improving contact transparency.

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.

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

BESIX operates as a full-service construction and concessions enterprise targeting clients in construction, infrastructure, and real estate sectors. The company leverages a network of subsidiaries to cover diverse geographic and sectoral markets. Their business model includes contracting, real estate development, and asset management. The presence of ESG reporting and innovation focus indicates a forward-looking strategy. The company targets institutional clients, investors, and potential employees. The website content and linked domains confirm a large enterprise with a comprehensive service offering and strong brand consistency.

Security posture

The website enforces HTTPS and integrates a cookie consent mechanism compliant with GDPR. However, it lacks explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No security.txt or vulnerability disclosure policy is found, and no incident response contacts are published. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security posture is good but could be improved by adopting additional best practices and transparency measures.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options.
  2. Publish a dedicated security policy and incident response contact information.
  3. Create and maintain a vulnerability disclosure program or security.txt file.
  4. Enhance transparency by providing clear company contact emails and phone numbers on the website.
  5. Regularly audit and update third-party scripts and tracking tools to minimize privacy risks.

Technical notes

Notes

The website is built on a modern React-based framework (Next.js) and uses Storyblok as its CMS, enabling dynamic content management and good performance. It integrates third-party services such as Google Tag Manager for analytics and OneTrust for cookie consent management. The site is mobile responsive and accessible, with good SEO metadata including Open Graph and JSON-LD structured data. Performance is moderate, with room for optimization in image loading and script management. Hosting provider details are not explicitly identified from the content. Overall, the technical infrastructure supports a professional and scalable web 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.
