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

6 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. 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"

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 NABU-Netz platform positions itself as a critical digital infrastructure for NABU's community engagement and operational support. Its business model is non-profit, focusing on providing value-added digital services to its members and volunteers. The ecosystem includes multiple specialized subdomains and services, indicating a mature digital strategy. The use of centralized authentication and integration with various service domains suggests a cohesive partnership ecosystem within NABU's digital offerings. The platform supports education, communication, and resource sharing, which are key to NABU's mission and member engagement.

Security posture

The website demonstrates a solid security foundation with HTTPS enforced and CSRF protection in place. The use of OpenID Connect for authentication enhances security by centralizing user management. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options is a gap that should be addressed. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact reduces transparency and preparedness perception. Overall, the security posture is good but can be improved with additional headers and formal policies.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Add a cookie consent banner or mechanism to comply fully with GDPR requirements and enhance user privacy transparency.
  3. Publish a clear security policy and incident response contact information to improve trust and readiness.
  4. Consider creating and publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit third-party libraries and dependencies to ensure no vulnerable components are in use.

Technical notes

Notes

The website is built on a modern Laravel backend with Livewire and Alpine.js for reactive frontend components. The use of Filament indicates a structured admin panel for content management. Performance is moderate with good mobile responsiveness and basic accessibility features. SEO is basic but present with proper meta tags and structured navigation. Analytics are handled via Matomo, favoring privacy. The technical stack is modern and well-maintained, though opportunities exist to enhance accessibility and SEO further. Hosting details are not explicit but DNS uses professional UI-DNS servers.
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.
