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

Business profile

Willy Naessens Industriebouw operates as an essential entity within the manufacturing and real estate sectors, focusing on industrial construction projects. Their business model leverages vertical integration to control the entire construction process, providing competitive advantages in quality, pricing, and scheduling. The company targets a broad customer base including SMEs, logistics companies, retailers, food industry clients, and public sector projects. Their market position as a leader in Belgium and Luxembourg is supported by a large portfolio of completed projects and a strong brand presence. The company is part of the larger Willy Naessens Group, which includes multiple subsidiaries in related sectors, enhancing their ecosystem and service offerings. Growth indicators include recent acquisitions and active participation in sustainability initiatives. The website and digital presence reflect a mature and professional operation with clear strategic focus.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and a detailed cookie consent mechanism aligned with GDPR. The absence of exposed sensitive data and use of reputable third-party analytics and marketing tools indicate good operational security. However, the lack of published security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap and potential risk in incident management. Security headers are limited, suggesting room for improvement in defense-in-depth strategies. No critical vulnerabilities or suspicious activities were detected in the analyzed content. Overall, the security maturity is good but could be enhanced by formalizing security governance and transparency measures.

Recommendations

  1. Implement additional HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to strengthen browser security.
  2. Publish a dedicated security policy page and provide clear incident response contact information to improve transparency and readiness.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance website accessibility features to meet higher compliance standards and improve user experience for all visitors.
  5. Regularly audit and update third-party scripts and tracking technologies to minimize security risks and ensure privacy compliance.

Technical notes

Notes

The website is built on a custom or proprietary CMS platform with a modern front-end stack including HTML5, CSS3, and JavaScript.

Hosting is provided by One.com A/S, a reputable registrar and hosting provider. Performance is moderate with good mobile optimization and SEO practices. Accessibility is basic and could be improved.

Opportunities exist to enhance security headers and accessibility compliance to reduce technical risks.
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.
