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

NABU - Naturschutzbund Deutschland e.V. is a well-established German non-profit organization dedicated to nature conservation and environmental protection. The website focuses on public awareness campaigns such as the 'Bird of the Year 2026' featuring the Rebhuhn (partridge), highlighting endangered species and promoting biodiversity. NABU enjoys a strong market position in Germany with a large membership base and extensive volunteer network. The site offers rich content, educational resources, and engagement opportunities for the general public and conservation enthusiasts. Technically, the website is built on the IMPERIA CMS platform, utilizing modern web technologies including Bootstrap, jQuery, and privacy-respecting analytics tools like Matomo. The site is mobile-optimized, accessible, and SEO-friendly. Cookie consent is managed via Klaro, ensuring GDPR compliance. The infrastructure appears stable with European-based DNS and hosting. From a security perspective, the site enforces HTTPS and employs cookie consent mechanisms. However, explicit security headers are not visible in the HTML source, and no public security policy or incident response contacts are provided. No vulnerabilities or suspicious content were detected. The site integrates tracking pixels from major platforms (Meta, TikTok, Google Ads) with user consent. Overall, NABU's website demonstrates a high level of professionalism, trustworthiness, and compliance with privacy regulations. It effectively serves its mission to educate and engage the public in environmental conservation. Strategic improvements could include publishing a dedicated security policy and enhancing security header implementation to further strengthen its security 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. 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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…
  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

NABU operates as a leading environmental NGO in Germany, focusing on biodiversity and nature conservation. Its business model relies on donations, memberships, and public campaigns. The organization targets environmentally conscious individuals, volunteers, and policymakers. NABU's competitive advantage lies in its long history, broad volunteer base, and recognized brand. The website supports these efforts by providing educational content, campaign information, and donation channels. Partnerships with regional NABU branches and related organizations enhance its reach. The site reflects a mature digital presence with consistent branding and high-quality content.

Security posture

The website maintains a good security posture with enforced HTTPS and GDPR-compliant cookie consent. Use of Matomo analytics indicates a privacy-conscious approach. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is a minor gap. No incident response or vulnerability disclosure information is publicly available, which could be improved to enhance transparency and readiness. No signs of vulnerabilities or data exposure were found. Overall, the security measures align with best practices for a non-profit organization but could be further strengthened.

Recommendations

  1. Publish a clear security policy and incident response contact information on the website.
  2. Implement and explicitly configure security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Consider adding a security.txt file to facilitate vulnerability disclosures.
  4. Regularly audit third-party scripts and tracking pixels to ensure privacy compliance.
  5. Enhance transparency around data retention policies and user data handling.

Technical notes

Notes

The website is built on the IMPERIA CMS platform version 8.6.0, leveraging Bootstrap for responsive design and jQuery for interactivity. It integrates ReadSpeaker for accessibility and Klaro for cookie consent management. Analytics are handled primarily via Matomo, supplemented by Google Tag Manager and tracking pixels from Meta and TikTok. The site is hosted on European name servers, suggesting compliance with EU data protection standards. Performance is moderate with asynchronous loading of scripts to optimize user experience. The site is mobile-optimized and accessible, with good SEO practices including meta tags and Open Graph data. Opportunities exist to modernize security headers and enhance incident response capabilities.
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.
