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

CSL Behring Österreich is a leading biotechnology company specializing in lifesaving biotherapeutics and plasma protein biotechnology. The company operates as a subsidiary of CSL Limited and maintains a strong market position worldwide. Their website reflects a professional and enterprise-grade digital presence, focusing on patient support, research and development, and healthcare professional resources. The site is well-structured with clear navigation and uses modern technologies such as Google Tag Manager and OneTrust for cookie consent, indicating a mature digital infrastructure. Security posture is solid with HTTPS enforced and cookie consent implemented, though explicit security policies and incident response contacts are absent. Privacy compliance is partially addressed through cookie consent but lacks a visible privacy policy and terms of service. Overall, the website is trustworthy and professionally maintained, suitable for its healthcare audience.

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. 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

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  2. 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';…

  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.

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 targets healthcare professionals, patients, and investors with a comprehensive range of biotherapeutic products and services. Their business model centers on research, development, production, and marketing of plasma protein biotherapeutics. The presence of investor relations and corporate annual reports links suggests transparency and a publicly accountable enterprise. The website's external links to parent and related domains reinforce the corporate structure and partnership ecosystem. Growth indicators include active patient support and expert roundtables in Austria. The company maintains a consistent brand image and clear communication channels primarily via contact forms.

Security posture

CSL Behring Österreich demonstrates a moderate to high security maturity level with HTTPS and cookie consent mechanisms in place. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure programs indicates room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The use of third-party scripts like Google Tag Manager and OneTrust is standard but requires ongoing monitoring for security risks. Compliance with GDPR is partially evident but would benefit from a published privacy policy and data protection officer contact information.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to enhance GDPR compliance and user trust.
  2. Implement and publicize a security policy and incident response contact channels to improve transparency and readiness.
  3. Consider adding a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  5. Add explicit security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen security posture.

Technical notes

Notes

The website uses a modern tech stack including Google Tag Manager for analytics and OneTrust for cookie consent management, indicating a focus on privacy and data governance. The Montserrat font and Brightcove video player are used for branding and multimedia content. The site is mobile optimized with good navigation clarity and professional design. Performance is moderate, with no critical technical debt observed in the provided content. However, no CMS or hosting provider information was detected, which could be further investigated. The site lacks some advanced SEO and accessibility features but maintains a solid foundation for enterprise healthcare digital presence.
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.
