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

Crohn en Colitis NL is a Dutch non-profit association dedicated to supporting approximately 90,000 people in the Netherlands affected by Crohn's disease, colitis ulcerosa, or short bowel syndrome. The organization provides patient support, information, and community engagement, positioning itself as a leading healthcare association in its niche. The website is built on WordPress using the FoundationPress theme and integrates modern tracking and consent technologies such as Google Analytics, Google Tag Manager, and Cookiebot. The technical infrastructure is solid with HTTPS enforced and Cloudflare services providing bot protection and performance enhancements. Security posture is strong with appropriate headers and no visible vulnerabilities, although the use of an outdated jQuery version presents a minor risk. Privacy compliance is well addressed with a comprehensive privacy policy and cookie consent mechanism. However, the absence of a terms of service page and explicit security policy or incident response contact information are areas for improvement. Overall, the website is professional, trustworthy, and well-suited for its target audience.

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

5 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
    • 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

The organization operates as a non-profit healthcare association focused on inflammatory bowel diseases in the Netherlands. Its business model centers on community support and information dissemination rather than commercial activities. The website targets patients and their families, providing resources and engagement opportunities. The presence of a dedicated partner domain for form handling indicates a structured approach to data collection and privacy. The association's market position is strong within its specialized healthcare sector, with clear branding and consistent messaging. Growth potential lies in expanding digital engagement and enhancing compliance and security transparency.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, strong security headers, and bot mitigation via Cloudflare. Cookie consent is implemented with detailed disclosures, supporting GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected. The main security concern is the outdated jQuery library, which should be updated to mitigate potential risks. The lack of a published security policy and incident response contacts limits transparency and preparedness. Overall, the site is secure for its purpose but would benefit from enhanced security governance documentation.

Recommendations

  1. Update jQuery to the latest stable version to reduce security risks.
  2. Publish a dedicated security policy page outlining security practices and commitments.
  3. Add incident response contact information such as security@ or abuse@ email addresses.
  4. Consider implementing a vulnerability disclosure policy or security.txt file.
  5. Enhance website accessibility features to improve compliance and user experience.

Technical notes

Notes

The website is built on WordPress with a child theme of FoundationPress, leveraging jQuery 2.2.4 and Google services for analytics and tag management. Cookiebot is used for cookie consent management, ensuring GDPR compliance. Hosting and CDN services appear to be provided by Cloudflare, enhancing security and performance. The site uses modern SEO practices with proper meta tags and structured data (JSON-LD). Performance is moderate with lazy loading and preloading optimizations. Technical debt is minimal but updating outdated libraries is recommended. The site is mobile optimized with good navigation and content structure.
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.
