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

8 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 strong position in the industrial manufacturing sector in Belgium, focusing on aluminium joinery and construction glass. Its business model is B2B, serving industrial clients with a focus on quality, sustainability, and expert service. The company has received sustainability certification, enhancing its market credibility. The website supports recruitment efforts through a linked partner domain, indicating growth and investment in human resources. The presence of multiple social media channels and a professional website indicates a mature digital presence. The company benefits from being part of the Willy Naessens Group, which provides vertical integration advantages and brand recognition.

Security posture

The website demonstrates a good security baseline with HTTPS and cookie consent mechanisms in place. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap. There is no visible incident response or security policy information, which could be improved to enhance trust and readiness. The site uses third-party scripts like Google Tag Manager, which should be regularly audited for security. Overall, the security posture is good but could be strengthened with additional headers and documented incident response processes.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Enhance accessibility features to improve compliance and user experience.
  4. Regularly review and audit third-party scripts and libraries for vulnerabilities.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations.

Technical notes

Notes

The website is built on a custom CMS platform (SiteMn) and uses standard web technologies such as HTML5, CSS3, and JavaScript. It integrates Google Tag Manager for analytics and tracking, and Plyr for video playback. Hosting is provided by One.com, a reputable provider. Performance is moderate with some optimization potential. The site is mobile responsive and has basic accessibility features. SEO is basic with meta tags present but no advanced structured data like JSON-LD detected. The technical infrastructure is stable but could benefit from modernization efforts such as improved accessibility and enhanced 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.
