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

CSL Behring Polska is a branch of the global biotechnology leader CSL Limited, specializing in innovative therapies for rare and serious diseases such as blood clotting disorders, immune deficiencies, hereditary angioedema, and alpha-1 antitrypsin deficiency. The website presents a professional and well-structured digital presence targeting patients, healthcare professionals, and potential employees in Poland. The content emphasizes the company's commitment to research, development, and patient support. Technically, the website employs modern web technologies including JavaScript, Google Tag Manager for analytics, OneTrust for cookie consent management, and Brightcove for video content delivery. The site is mobile-optimized, accessible, and SEO-friendly, though no specific CMS or hosting provider information is evident. Performance is moderate with room for optimization. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms, but lacks visible security headers and explicit privacy or terms of service documentation. No vulnerability disclosure or incident response contacts are provided, which could be improved to enhance trust and compliance. The absence of WHOIS data limits domain legitimacy verification, but the overall professionalism and content quality suggest a legitimate enterprise. Overall, the website is a solid representation of a healthcare enterprise with good content and technical implementation but would benefit from enhanced transparency in privacy, security policies, and domain registration details.

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

CSL Behring Polska operates within the healthcare sector, focusing on biopharmaceutical products for rare diseases. The company leverages its global parent company's resources and brand to maintain a strong market position in Poland. Its business model centers on research-driven development and supply of innovative medicinal products, targeting patients with rare and serious conditions. The website supports recruitment efforts and patient education, indicating a comprehensive approach to stakeholder engagement. The lack of explicit revenue or partnership disclosures limits deeper financial or ecosystem insights, but the presence of global branding and localized content suggests a mature operation with enterprise scale.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is enforced, and cookie consent is managed via a reputable third-party solution (OneTrust). However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces defense-in-depth. No explicit privacy policy or terms of service pages were found, which are critical for GDPR compliance and user trust. The lack of a security.txt or vulnerability disclosure mechanism limits transparency and incident response readiness. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security posture is adequate but could be significantly improved with better policy documentation and security header implementation.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages prominently linked on the website.
  2. Implement essential security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  3. Provide explicit contact information for data protection officers and security incident response teams.
  4. Consider adding a security.txt file to facilitate vulnerability disclosure and improve transparency.
  5. Regularly audit and update third-party scripts and tracking technologies to minimize security risks.

Technical notes

Notes

The website uses modern JavaScript frameworks and integrates third-party services such as Google Tag Manager for analytics and OneTrust for cookie consent management. Brightcove is used for video content delivery, indicating a multimedia-rich experience. The site is mobile-optimized and accessible, with good SEO meta tags and Open Graph data for social sharing. No CMS or hosting provider details were identified, suggesting a custom or proprietary platform. Performance is moderate, with potential for optimization in loading times and script management. The site structure is clear with well-organized navigation menus and search functionality. Overall, the technical infrastructure supports a professional user experience but could benefit from enhanced performance tuning and security hardening.
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.
