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

Seveton is a Belgian manufacturing company specializing in prefab concrete wall elements, insulated panels, and concrete roof and floor elements. Established in 1997 and part of the Willy Naessens Group, it holds a strong market position in the Benelux and France with significant production capacity. The website is professionally designed, multilingual, and provides comprehensive information about products, sustainability efforts, certifications, and job opportunities. Technically, the site uses modern web technologies and includes a cookie consent mechanism, though no explicit CMS or advanced frameworks are detected. Security posture is solid with HTTPS and certifications like CSC, but could be improved by adding security headers and incident response contacts. Overall, the site is trustworthy and compliant with GDPR, supporting a positive business credibility profile.

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

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

Seveton operates in the manufacturing sector focused on prefab concrete construction elements, targeting construction professionals and companies. Its competitive advantage lies in its large production capacity and certifications ensuring quality and sustainability. The business model is B2B manufacturing and supply, supported by the parent company Willy Naessens Group. The company emphasizes sustainability and continuous improvement, which aligns with market trends. Partnerships with related prefab system providers and job recruitment platforms indicate a healthy ecosystem. The website content and structure support clear communication of business offerings and corporate values.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is used, and cookie consent is implemented with detailed categories, reflecting GDPR compliance. The presence of CSC certification indicates adherence to industry standards for sustainability and safety. However, no explicit security headers were detected in the provided data, and there is no published incident response or vulnerability disclosure information. No vulnerabilities or exposed sensitive data were found in the HTML content. To enhance security posture, the company should implement security headers, publish incident response contacts, and consider a vulnerability disclosure policy.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish clear incident response contact information or a dedicated security email address.
  3. Create and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance website accessibility features to improve compliance and user experience.
  5. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses standard HTML5, CSS3, and JavaScript with external libraries like Font Awesome, Ion Icons, and Plyr for media playback. The hosting registrar is One.com A/S, consistent with the WHOIS data. The site is multilingual with language switchers and uses preloading for fonts to improve performance. The design is responsive and mobile-friendly with a clear navigation structure. No CMS is explicitly detected, suggesting a custom or proprietary solution. Performance is moderate with some external dependencies. There is room for improvement in accessibility and SEO, though meta tags and Open Graph tags are present. No critical technical debt or risks were identified from the provided data.
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.
