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. 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 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

The association holds a strong market position as the official representative body for chimney sweeps in Germany. Its business model is non-profit and focused on advocacy, education, and service facilitation. The website supports this by providing detailed information, partner links, and regional search tools. The presence of multiple regional partner domains indicates a broad network. The site’s content and structure support transparency and user engagement, enhancing credibility and trust.

Security posture

The website enforces HTTPS and uses cookie consent tools to comply with privacy regulations. No exposed sensitive data or vulnerable libraries were detected. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. No incident response or security policy pages were found, which could be beneficial for transparency and preparedness. Overall, the security posture is solid but could be enhanced with additional headers and documented policies.

Recommendations

  1. Implement Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers to strengthen security.
  2. Add a dedicated security policy and incident response page to improve transparency and readiness.
  3. Regularly audit third-party scripts and update dependencies to mitigate vulnerabilities.
  4. Consider adding a terms of service page to clarify user agreements and liabilities.
  5. Enhance accessibility features and continue optimizing mobile responsiveness.

Notes

The website uses Drupal 10 CMS with Bootstrap 5 and jQuery for frontend functionality. It integrates Matomo for analytics and YouTube IFrame API for video content, managed with a cookie consent framework (CookiesJSR). The site is mobile optimized with responsive design and accessibility considerations. Performance is moderate, with potential improvements in caching and asset optimization. The technical stack is modern and well-maintained, supporting a professional user experience.
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.
