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

Willy Naessens Infra is a specialized industrial construction company focused on groundwork and infrastructure services, operating as part of the larger Willy Naessens Group. The company offers a comprehensive range of services including demolition, groundworks, concrete, foundation, leveling, driveway and parking construction, sewer works, and water features. Their market position is that of an important regional player within Belgium, supporting vertical integration strategies of their parent group. The website is professionally designed, multilingual, and provides clear contact and service information, targeting industrial clients and businesses requiring groundwork services. Technically, the website uses modern web standards with HTML5, CSS3, and JavaScript, including Google Tag Manager for analytics and a video player library. Hosting appears stable with One.com as registrar and content delivery via sitemn.gr. The site is mobile optimized and performs moderately well, though accessibility features are basic. SEO is implemented at a basic level with meta tags and structured navigation. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms compliant with GDPR. No critical vulnerabilities or exposed sensitive data were detected. However, the site lacks a dedicated security policy or incident response contact information, which could improve trust and compliance. Overall, the security posture is good but could be enhanced with additional headers and transparency. The overall risk assessment is low with no blocking or WAF detected, and the domain registration data aligns well with the business claims. Strategic recommendations include publishing a security policy, adding incident response contacts, improving accessibility, and enhancing security headers to strengthen the security posture and trustworthiness.

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"

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.

Business context

Business profile

Willy Naessens Infra operates in the industrial construction sector with a focus on groundwork and infrastructure. Their business model leverages vertical integration within the Willy Naessens Group, providing specialized groundwork services that complement the group's broader construction activities. The company targets industrial clients requiring preparatory construction services. Their competitive advantage lies in their integration within a large group, enabling comprehensive project delivery. Revenue streams likely come from industrial construction contracts and related groundwork services. Growth indicators include active recruitment and sustainability initiatives. The partnership ecosystem includes related group websites and sustainability platforms, enhancing brand coherence and market reach. The company maintains a professional digital presence with clear service offerings and contact channels, supporting business development and client engagement.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS encryption and a cookie consent mechanism aligned with GDPR requirements. No exposed sensitive data or vulnerable libraries were found in the HTML content. However, the absence of a published security policy and incident response contact limits transparency and readiness perception. The site could benefit from implementing additional security headers such as Content-Security-Policy and X-Content-Type-Options to mitigate common web threats. There is no evidence of a vulnerability disclosure program or security.txt file, which are best practices for responsible vulnerability management. Overall, the security maturity is good but can be improved to meet higher compliance and trust standards.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Add incident response contact information (e.g., security@ or abuse@ email) to improve transparency and readiness.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance website security headers to include Content-Security-Policy, X-Content-Type-Options, and others.
  5. Improve accessibility features to comply with WCAG standards and enhance user experience for all visitors.

Technical notes

Notes

The website is built with standard modern web technologies including HTML5, CSS3, and JavaScript. It uses Google Tag Manager for analytics and a third-party video player library (Plyr). The site appears to be custom-built or uses a proprietary CMS, as no common CMS signatures were detected. Hosting is likely provided by One.com or related providers, with content delivery via sitemn.gr domains. Performance is moderate with some preloading of fonts and deferred script loading. Mobile optimization is good with viewport meta tags and responsive CSS. SEO is basic with meta keywords and descriptions present but empty. Accessibility is basic with some ARIA roles and language attributes but could be improved. Overall, the technical infrastructure is solid but could benefit from modernization and enhanced SEO and accessibility practices.
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.
