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

  • Security headers: did not complete in this scan.
  • 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 platform occupies a niche in the German educational market focused on environmental and biodiversity education. Its non-profit model offers free access to learning materials, supported by affiliations with NABU and governmental environmental bodies. The presence of diverse courses and thematic categories indicates a broad content offering aimed at various species groups and habitats. The website's partnership with recognized environmental organizations and use of open licenses for images supports its authoritative position. Growth potential lies in expanding course offerings and enhancing user engagement through interactive tools.

Security posture

The website enforces HTTPS and uses SAML for authentication, indicating a secure access control approach. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers such as Content Security Policy or HSTS suggests room for improvement. The lack of a published security policy or incident response contacts limits transparency in security governance. Use of Matomo analytics reflects a privacy-conscious approach but cookie consent mechanisms are missing, which may affect GDPR compliance. Overall, the security posture is solid but could benefit from enhanced header policies and formal security documentation.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Add a visible cookie consent banner to comply with GDPR and inform users about tracking.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website leverages the ILIAS LMS platform, a mature and widely used learning management system. It integrates multiple JavaScript libraries such as jQuery, Bootstrap, MathJax, and MediaElement.js for rich content delivery and interactivity. Hosting is managed via RZONe, with domain nameservers indicating stable infrastructure. The site is mobile-optimized with responsive design elements and uses SVG and WebP images for performance.

Overall, the technical infrastructure is robust and suitable for the educational content delivered.
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.
