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

CSL Behring Schweiz operates as a significant player in the healthcare sector, specializing in the development and manufacturing of innovative bio-therapeutics derived from human blood plasma. The company serves patients, healthcare professionals, and partners, focusing on rare and serious diseases. Their Swiss operations include research and development, manufacturing, and patient support, positioning them as a trusted healthcare provider in the region. The website reflects a professional and consistent brand image aligned with their global parent company, CSL Limited. Technically, the website employs modern technologies such as Google Tag Manager for analytics, OneTrust for cookie consent management, and Brightcove for video content delivery. The site appears to be built on a CMS likely to be Sitecore, given URL patterns and typical enterprise usage. Performance and mobile optimization are adequate, though accessibility features could be improved. SEO metadata is present but basic. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms, which are positive indicators. However, the absence of explicit security headers, vulnerability disclosure information, and a published security policy limits the security maturity level. No critical vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the website is trustworthy and professionally maintained, with room for improvement in privacy policy transparency and security best practices. The domain registration data aligns well with the business claims, supporting legitimacy. Strategic enhancements in security posture and privacy compliance would further strengthen the company's digital trustworthiness.

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

2 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 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

Business profile

CSL Behring Schweiz is positioned as a large healthcare entity focused on plasma-derived therapeutics and rare disease treatments. Their business model revolves around manufacturing, research, and patient engagement. The company benefits from a strong global parent, CSL Limited, enhancing market credibility. The website targets patients, healthcare professionals, and partners, indicating a B2B and B2C hybrid approach. The presence of localized content and language options suggests a focus on the Swiss market while maintaining global integration. The partnership ecosystem includes CSL's global network, but no additional partner domains were identified in the content. Growth indicators include active R&D and patient support initiatives. The company leverages digital tools for marketing and analytics but maintains a conservative approach to direct contact information, favoring contact forms. This may reflect regulatory compliance considerations in healthcare communications.

Security posture

The website demonstrates a moderate security posture with mandatory HTTPS and cookie consent mechanisms in place. However, the lack of visible security headers such as Content-Security-Policy, X-Frame-Options, and others indicates potential areas for enhancement. No incident response or security contact information is published, which could hinder timely vulnerability reporting and response. The absence of a vulnerability disclosure policy or security.txt file further limits transparency. No signs of exposed sensitive data, malware, or phishing were detected. The use of reputable third-party services like Google Tag Manager and OneTrust suggests adherence to standard security and privacy practices. Overall, the security maturity is adequate for a corporate healthcare website but would benefit from formalized policies and technical hardening.

Recommendations

  1. Publish a comprehensive privacy policy page clearly accessible from the homepage.
  2. Implement and configure security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance accessibility features to meet recognized standards (e.g., WCAG 2.1).
  5. Improve SEO metadata completeness and structured data usage for better search engine visibility.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager for analytics, OneTrust for cookie consent, and Brightcove for video content. The probable use of Sitecore CMS indicates an enterprise-grade content management system. The site is mobile optimized with responsive design elements and includes accessibility features, though these could be improved. Performance is moderate, with no critical issues detected in the HTML content. The site uses canonical links and basic Open Graph metadata, but lacks JSON-LD structured data. External dependencies are limited to trusted domains. There is no evidence of outdated or vulnerable libraries in the provided content.
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.
