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

The organization operates as a non-profit in the healthcare sector, focusing on cancer-related services including patient support, prevention, and research. Its business model revolves around providing free information and support services, funded likely through donations and partnerships. The website integrates payment processing via RaiseNow, indicating active fundraising efforts. The presence of multiple marketing and analytics tools suggests a mature digital marketing strategy aimed at outreach and engagement. The organization’s partnerships with reputable service providers enhance its operational capabilities. The website’s content and structure reflect a well-established entity with a clear target audience and professional presentation, supporting its strong market position in Switzerland.

Security posture

The website exhibits a mature security posture with HTTPS enforced and no visible exposure of sensitive data. The use of a detailed cookie consent banner with granular controls aligns with GDPR requirements, enhancing user privacy. Integration of reputable third-party analytics and marketing services is managed with user consent. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not explicitly detected and should be verified or implemented to strengthen defenses against common web attacks. No vulnerabilities or suspicious activities were detected in the HTML content. The absence of a published security policy or incident response contact is a minor gap. Overall, the site is secure but could benefit from formalizing security documentation and headers.

Recommendations

  1. Implement and verify explicit security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a formal security policy and incident response contact information on the website.
  3. Regularly audit third-party scripts and libraries for vulnerabilities and update them promptly.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Maintain transparency and update privacy and cookie policies regularly to reflect any changes in data processing.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust open-source content management system, enhanced with jQuery and Bootstrap for frontend interactivity and responsiveness. It uses Google Tag Manager to manage multiple analytics and marketing tags efficiently. Performance is moderate, likely influenced by multiple third-party scripts, but mobile optimization and accessibility are well addressed. The site uses Cloudflare services for CDN and security enhancements. SEO is supported by proper meta tags, Open Graph data, and JSON-LD structured data. The technical infrastructure is modern and well-maintained, with opportunities to improve security headers and streamline third-party integrations for performance gains.
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.
