Risk levelLow

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

Longfonds is a Dutch non-profit organization dedicated to promoting healthy lungs and clean air for everyone. The website serves as a platform for health advocacy, supporting scientific research, and raising public awareness about respiratory health. The organization targets the general public concerned with lung health and related issues. The website is built on Drupal 10 and integrates modern marketing and analytics tools such as Google Analytics, Google Tag Manager, Visual Website Optimizer, and Cookiebot for cookie consent management. The technical infrastructure reflects a moderate level of digital maturity with good mobile optimization and basic accessibility features. Security posture is adequate with HTTPS enforced and cookie consent implemented, but lacks publicly visible security policies and incident response information. Overall, the website is professional, trustworthy, and safe for general audiences, though it would benefit from publishing explicit privacy, terms of service, and security policies to enhance compliance and transparency.

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 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Longfonds operates as a health-focused non-profit in the Netherlands, positioning itself as a key advocate for lung health and clean air. Its business model revolves around advocacy, research support, and public education rather than commercial sales. The organization leverages partnerships and digital marketing tools to engage its audience and promote its mission. The website content and structure indicate a medium-sized organization with consistent branding and good content quality. The absence of direct contact details in the analyzed content suggests contact information may be located elsewhere or behind navigation. The use of advanced analytics and marketing tools indicates an investment in digital engagement and user experience.

Security posture

The website enforces HTTPS and uses cookie consent mechanisms, reflecting awareness of privacy and security best practices. However, there is no visible security policy, incident response plan, or dedicated contact channels for security issues. Security headers were not detected in the provided data, and no vulnerabilities or exposed sensitive data were found. The integration of third-party scripts such as Google Analytics and VWO introduces potential risk vectors that should be regularly audited. Overall, the security posture is moderate but could be improved by publishing security policies, implementing additional HTTP security headers, and providing incident response contacts.

Recommendations

  1. Publish a comprehensive privacy policy page clearly accessible from the website footer or main navigation.
  2. Add terms of service and security policy pages to improve transparency and compliance.
  3. Provide explicit contact information including security incident response contacts (e.g., security@longfonds.nl or abuse@longfonds.nl).
  4. Implement and verify HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  5. Regularly audit third-party scripts and tracking tools to minimize security and privacy risks.

Technical notes

Notes

The website is built on Drupal 10, a modern and widely used CMS platform, indicating a solid technical foundation. It uses Google Tag Manager to manage analytics and marketing tags, along with Visual Website Optimizer for A/B testing and optimization. Cookie consent is managed by Cookiebot, supporting GDPR compliance. The site loads asynchronously many scripts from trusted domains, which helps performance. Mobile optimization is good, but accessibility features appear basic. No hosting provider information was detected. Performance is moderate, likely influenced by multiple third-party scripts. The site would benefit from enhanced SEO and accessibility improvements to further improve user experience and reach.
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.
