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

The Vereniging van Waterbouwers is a well-established Dutch association representing the water construction sector. With a history spanning approximately 90 years, it serves as a key advocate and knowledge-sharing platform for its members and the broader public interested in water construction. The website reflects a professional and consistent brand presence, targeting industry professionals and stakeholders. Technically, the site is built on a legacy ASP.NET WebForms platform with modern JavaScript libraries such as jQuery and Splide.js for UI enhancements. Google Tag Manager and AddThis are used for analytics and social sharing, indicating moderate digital maturity. Security-wise, the site enforces HTTPS and implements CSRF tokens but lacks explicit security headers and cookie consent mechanisms, which are areas for improvement. Overall, the site is trustworthy, safe, and compliant with basic GDPR requirements, though it could enhance privacy and security policies to strengthen its posture.

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

4 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 association operates as a non-profit entity focused on advocacy, knowledge dissemination, and sector promotion within the Dutch water construction industry. Its market position is strong due to its long-standing history and active engagement with members through thematic content, news, and events. The business model centers on member services and sector representation rather than commercial sales. The website supports this with detailed thematic sections and member highlights. The presence of multiple social media channels and a news section indicates active communication and outreach. No direct revenue streams or commercial partnerships are evident from the site, consistent with a non-profit association model.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is properly enforced, and CSRF protection is implemented in forms, which are positive indicators. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security reduces the overall security posture. No incident response or security policy information is published, which could hinder transparency and readiness. The use of legacy ASP.NET WebForms technology may pose risks if not regularly updated. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site should improve cookie consent compliance and publish security-related policies to enhance trust and compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  2. Add a cookie consent banner and mechanism to comply with EU cookie laws and improve privacy compliance.
  3. Publish a clear security policy and incident response contact information to enhance transparency and readiness.
  4. Regularly audit and update third-party scripts and legacy platform components to mitigate vulnerabilities.
  5. Enhance accessibility features and SEO optimization to improve user experience and search visibility.

Key observations

  1. Website is a professional association site for the Dutch water construction sector.
  2. Content is in Dutch and well-structured with thematic and news sections.
  3. No signs of phishing, malware, or suspicious content.
  4. No cookie consent banner detected, which may be a compliance gap.
  5. Use of legacy ASP.NET WebForms technology indicates a mature but somewhat dated platform.
  6. Social media presence is active and linked.
  7. No explicit security or incident response policies published.
Technical notes

Notes

The website is built on a mature ASP.NET WebForms CMS platform, which is stable but dated. It uses modern JavaScript libraries like jQuery 3.6.1 and Splide.js for interactive elements such as sliders and carousels. Google Tag Manager is used for analytics, and AddThis provides social sharing capabilities. The site is mobile-optimized with responsive design elements and clear navigation. Performance is moderate, with no major issues detected. However, the lack of modern security headers and cookie consent mechanisms indicates some technical debt in security and privacy compliance. The infrastructure appears self-hosted or managed without clear hosting provider information. Overall, the technical implementation supports the business needs but could benefit from modernization and enhanced security controls.
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.
