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

7 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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 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';…

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.

Dark web exposure

Add-on

Technical appendix

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

Business context

Business profile

The company operates in the healthcare sector, specifically biotechnology and biotherapies, serving patients with rare and serious diseases. It is positioned as a large enterprise with a strong market presence in France and is a subsidiary of CSL Limited. The business model focuses on research and development, product innovation, and collaboration with healthcare professionals and patient associations. The website's content and navigation indicate a well-structured approach to customer engagement and regulatory compliance. The presence of external links to the parent company and use of professional branding reinforce its credibility. No direct revenue streams or financial data are disclosed, but the focus on innovation and partnerships suggests a sustainable growth strategy.

Security posture

The website demonstrates a good security maturity level with HTTPS enabled and multiple security headers present, reducing common web vulnerabilities. The use of cookie consent mechanisms aligns with GDPR requirements, and no sensitive data exposure or vulnerable libraries were detected in the HTML content. However, the absence of a public security policy, incident response contacts, or vulnerability disclosure mechanisms indicates room for improvement in transparency and incident readiness. No signs of malware or phishing were found. Overall, the security posture is solid but could benefit from enhanced communication of security practices and incident handling procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide clear incident response contact information to improve transparency and trust.
  4. Add explicit Data Protection Officer contact details to enhance GDPR compliance visibility.
  5. Regularly review and update security headers and cookie consent mechanisms to maintain compliance with evolving standards.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager for analytics and OneTrust for cookie consent management, indicating a focus on privacy and data protection. Brightcove is used for video content delivery. The site is well-structured with responsive design and accessibility features, providing a good user experience across devices. Performance is moderate, with no major issues detected in the HTML content. The absence of a detected CMS suggests a custom or proprietary platform. Hosting provider details are not evident from the HTML. SEO is supported by proper meta tags and Open Graph data, enhancing social media sharing and search engine visibility. Opportunities exist to improve technical documentation of security and compliance features.
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.
