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

3 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain:

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory

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 organization positions itself as a key government service provider impacting over 1.5 million citizens. Its business model focuses on public service delivery with a strong societal responsibility. The website targets Dutch citizens requiring healthcare-related services and professionals seeking employment. The presence of structured navigation, clear content, and social media integration indicates a mature digital presence. No direct commercial partnerships or subsidiaries are evident from the data. The organization maintains a consistent brand and messaging aligned with government standards.

Security posture

The website enforces HTTPS and includes a cookie consent banner with opt-in/out options, reflecting compliance with privacy regulations. No security headers were detected in the HTML content, suggesting room for improvement in defense-in-depth. There is no published security policy or incident response contact, which could enhance transparency and trust. No vulnerabilities or exposed sensitive data were found in the analyzed content. The use of modern frameworks and absence of outdated libraries indicate a low risk of technical vulnerabilities. Overall, the security posture is good but could benefit from additional formal policies and headers.

Recommendations

  1. Implement and publish explicit security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and user trust.
  3. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance cookie consent details with explicit data retention and third-party sharing information.
  5. Regularly audit third-party scripts and tracking tools to ensure compliance with privacy regulations.

Technical notes

Notes

The website uses a modern JavaScript framework (Nuxt.js) and a CMS backend (RudderCMS) with API-driven content. It preloads fonts and scripts for performance optimization and includes accessibility features such as skip links and high contrast mode. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. External dependencies include CDN-hosted assets and Google Analytics/Tag Manager for tracking. No major technical debt or performance bottlenecks are evident from the HTML content. The site could improve by adding security headers and further optimizing third-party script loading.
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.
