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

Interton holds a solid position within the prefab concrete manufacturing industry in Belgium, supported by its parent company Willy Naessens Group. The business model focuses on producing specialized concrete elements for construction and infrastructure projects, targeting professional clients. The company benefits from a modern factory with large production capacity and strategic location. Its digital presence is integrated with partner and parent company sites, enhancing recruitment and product marketing efforts. The absence of visible analytics or advertising scripts suggests a focus on direct business communication rather than broad consumer marketing. The company’s growth potential is supported by its ESG and sustainability commitments as highlighted on the site.

Security posture

The website demonstrates a baseline security posture with HTTPS enabled and a cookie consent mechanism in place, supporting GDPR compliance. However, there is no visible security policy, incident response contact, or vulnerability disclosure information, which are important for mature security governance. No security headers were detected in the HTML content, and no known vulnerable libraries were found. The lack of published security documentation and incident response channels may limit trust for security-conscious partners or clients. Overall, the security posture is moderate but could be improved by adding explicit policies and technical security headers.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement and configure HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear incident response contact information, including security or abuse email addresses.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features and SEO optimization to improve user experience and search visibility.

Technical notes

Notes

The website is built on a custom or proprietary platform using standard web technologies including HTML5, CSS3, and JavaScript. It uses external libraries such as Font Awesome for icons and Plyr for video playback. The site is mobile responsive and includes a cookie consent modal for privacy compliance. Hosting is likely provided by One.com A/S, the domain registrar. Performance is moderate with no major issues detected, but there is room for improvement in SEO and accessibility. No CMS or major frameworks were identified, suggesting a lightweight custom implementation. The site does not use common analytics or marketing tools, indicating a focus on direct business communication rather than broad digital marketing.
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.
