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

6 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. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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

Bellevue Group AG operates as a specialized asset manager with a focus on healthcare and entrepreneurial investments. Its business model emphasizes active management and scalable growth, serving a diverse investor base. The company maintains partnerships with related investment entities such as BB Biotech and Bellevue adbodmer, enhancing its market reach. The website content and structure indicate a mature digital presence with strong investor communication channels, including corporate news, insights, and detailed product information. The firm appears well-positioned in the Swiss and European financial markets, leveraging its niche expertise to differentiate from competitors.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and a cookie consent mechanism aligned with GDPR requirements. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a dedicated security policy page and incident response contact details suggests room for improvement in transparency and readiness. The use of third-party scripts like Google Tag Manager is managed with consent, but ongoing monitoring for vulnerabilities in dependencies is recommended. Overall, the security maturity is good but could be enhanced by formalizing security governance disclosures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement a vulnerability disclosure program or publish a security.txt file to encourage responsible reporting.
  4. Enhance website accessibility features to improve compliance and user experience for all users.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on the Neos CMS platform using the Flow PHP framework, indicating a modern and flexible infrastructure. It employs JavaScript libraries such as Alpine.js for interactivity and Glide.js for carousels, with LazySizes for image lazy loading to optimize performance. Google Tag Manager is used for analytics and marketing integration. The site is mobile-optimized with responsive design and includes SEO best practices such as meta tags and structured data (JSON-LD). Performance is moderate, with potential for improvement in loading speed and accessibility compliance. The technical stack supports a professional and scalable digital presence suitable for a medium-sized financial services firm.
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.
