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

Alpreco is a Belgian manufacturing company specializing in the production of prefabricated concrete elements such as reinforced concrete columns, beams, and I-beams with variable and constant heights. Established in 1999 and part of the Willy Naessens Group since 2003, Alpreco holds several industry certifications including CSC and KIWA, reinforcing its reputation as a reliable and sustainable player in the prefab concrete sector. The website reflects a professional B2B focus with clear product offerings and sustainability commitments. Technically, the site uses modern web technologies including Google Tag Manager and Plyr for video content, with a moderate performance and good mobile optimization. Security posture is adequate with HTTPS assumed and cookie consent implemented, though there is room for improvement in security headers and incident response transparency. Overall, the site is trustworthy and well-aligned with the company's business 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
      • 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

Alpreco operates in the manufacturing sector focused on prefab concrete elements, targeting construction industry clients requiring standardized, industrially produced concrete components. Its integration within the Willy Naessens Group provides scale and market positioning advantages. The company emphasizes sustainability and quality certifications, which serve as competitive differentiators. The website's linkage to related group domains and recruitment portals indicates a structured partnership ecosystem and growth orientation. Revenue streams likely derive from large-scale industrial contracts and customized prefab solutions. The business model is industrial manufacturing with a focus on standardization and quality assurance.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage and cookie consent mechanisms in place, supporting GDPR compliance. However, no explicit security policy or incident response contacts are published, and no security.txt file is found, which limits transparency for vulnerability reporting. The absence of visible security headers suggests potential gaps in defense-in-depth. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The use of Google Tag Manager introduces moderate tracking but is managed with cookie consent. Overall, the security posture is functional but could be enhanced by formalizing policies and improving technical controls.

Recommendations

  1. Implement and publish a dedicated security policy and incident response contact information to improve transparency and trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen protection against common web attacks.
  3. Create and maintain a security.txt file to facilitate responsible vulnerability disclosure.
  4. Conduct regular audits of third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance accessibility compliance and SEO optimization to improve user experience and search visibility.

Technical notes

Notes

The website is built with standard HTML5, CSS3, and JavaScript, incorporating Google Tag Manager for analytics and Plyr for video playback. No specific CMS or framework is detected, suggesting a custom or lightweight platform. Hosting details are limited but the registrar is One.com A/S, a reputable provider. Performance is moderate with good mobile responsiveness. The site uses multiple external scripts and fonts loaded from third-party CDNs. There is some redundancy in script loading (multiple menu scripts repeated), which could be optimized. SEO metadata is basic with empty keywords and description tags, indicating room for improvement. Accessibility features are basic, with an IE warning script but no advanced ARIA or semantic enhancements detected.
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.
