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

NFK (Nederlandse Federatie van Kankerpatiëntenorganisaties) is a well-established Dutch non-profit organization advocating for over 900,000 people living with or after cancer, including those with hereditary predispositions. The website reflects a mature digital presence with comprehensive content focused on patient participation, advocacy, and support services. It targets patients, volunteers, and healthcare professionals, positioning itself as a leading federation in the Dutch cancer care landscape. Technically, the site uses modern web technologies, including Google Analytics with IP anonymization, and is optimized for mobile and accessibility. Security posture is good with HTTPS enforced and cookie consent mechanisms, though some security headers and DNSSEC are missing. No critical vulnerabilities or exposed sensitive data were found. Overall, the domain registration data aligns well with the organization's identity, supporting high legitimacy and trust.

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 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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.

Breach exposure

Dark web exposure

Add-on

Leaked records that mention nfk.nl, from OffSeq Breach.

No leaked records found

Breach holds no records for nfk.nl right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

NFK operates in the healthcare and non-profit sectors, focusing on cancer patient advocacy and support. Its business model centers on representing patient organizations, influencing healthcare policy, and providing resources and campaigns to improve cancer care quality and patient quality of life. The organization benefits from partnerships with recognized entities like KWF and maintains a strong presence through affiliated domains. The website content and structure indicate a professional and consistent brand with clear communication channels and engagement opportunities for patients and volunteers. Growth indicators include active campaigns, webinars, and insight publications. The partnership ecosystem is robust, enhancing credibility and outreach.

Security posture

The website demonstrates a solid security foundation with HTTPS and anonymized analytics tracking. However, it lacks explicit security policies, incident response contacts, and advanced security headers, which are recommended for enhanced protection and transparency. The absence of DNSSEC is a minor gap in DNS security. No signs of vulnerabilities or data leaks were detected in the analyzed content. The cookie consent mechanism aligns with GDPR requirements, supporting privacy compliance. Overall, the security maturity is moderate to good but could be improved with additional policies and technical controls.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  3. Publish a dedicated security policy and provide incident response contact information to improve transparency and readiness.
  4. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Regularly review and update privacy and cookie policies to maintain compliance with evolving regulations.

Technical notes

Notes

The website uses a modern tech stack with custom JavaScript, CSS, and web fonts, and integrates Google Analytics with privacy considerations. It employs Swiper.js for interactive sliders and supports progressive web app features via a manifest file. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured data (JSON-LD). Hosting provider and CMS are not explicitly identified, suggesting a custom or proprietary solution. Performance is moderate, with some images showing loading errors possibly due to lazy loading or CDN issues. Overall, the technical infrastructure supports a professional and user-friendly experience but could benefit from performance optimizations and clearer CMS identification.
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.
