CSL Behring · Healthcare · Sweden

Medium risk. 2 critical or high findings in Security headers and SSL/TLS.

Security score

72/100

Risk levelMedium

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

CSL Behring Sverige operates as a regional presence of the global biotechnology leader CSL Behring, specializing in the development and manufacturing of plasma-based therapies and biotherapeutics for rare and serious diseases. The website reflects a professional and consistent brand image aligned with the global entity, targeting healthcare professionals and patients in Sweden. The digital infrastructure incorporates modern technologies such as Google Tag Manager and OneTrust for privacy compliance, with a focus on user experience and content relevance. Security posture is adequate with HTTPS and cookie consent mechanisms, though lacks some advanced security headers and explicit security policies. The absence of WHOIS data for the exact domain queried suggests it may be a subdomain or alias, which slightly reduces trust but does not negate the professional presentation. Overall, the website is a credible and safe source of information for its intended 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

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

Business context

Business profile

CSL Behring holds a strong market position as a global biotechnology company focused on rare diseases and plasma therapies. The Swedish site supports this positioning by providing localized content and services. The business model centers on pharmaceutical development and plasma collection, serving healthcare providers and patients. The company benefits from a well-established parent company, CSL Limited, enhancing credibility. The website's use of professional branding, privacy compliance tools, and analytics indicates a mature digital presence. However, the lack of direct contact details and WHOIS transparency may limit some user trust. The company likely leverages partnerships and a global network, though no explicit partner domains were identified in the content.

Security posture

The website employs HTTPS and integrates cookie consent via OneTrust, demonstrating compliance with GDPR and privacy best practices. However, the absence of visible security headers such as Content-Security-Policy or X-Frame-Options suggests room for improvement in defense-in-depth. No vulnerability disclosures or incident response contacts are published, which could hinder transparency in security matters. The lack of WHOIS data for the domain is a concern for domain legitimacy verification. No signs of malware, phishing, or WAF blocking were detected, indicating a clean security status. Overall, the security posture is moderate but could be enhanced by publishing security policies, adding security headers, and improving domain registration transparency.

Recommendations

  1. Implement and publish a security.txt file or vulnerability disclosure policy to improve transparency and incident response readiness.
  2. Add and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  3. Clarify domain registration details or ensure WHOIS data is publicly available to enhance trustworthiness.
  4. Provide direct company contact emails and phone numbers on the website to improve user trust and accessibility.
  5. Regularly audit and update privacy and security compliance measures to maintain GDPR and industry standards.

Technical notes

Notes

The website uses modern web technologies including Google Tag Manager for analytics and OneTrust for cookie consent management, indicating a focus on privacy compliance and user tracking control. The presence of VideoJS and Brightcove player libraries suggests multimedia content support. The site uses the Montserrat font and custom CSS bundles for styling. Performance appears moderate with no evident blocking scripts or heavy resources. Mobile optimization is good, with responsive meta tags and layout considerations. Accessibility is basic but could be improved with more ARIA roles and semantic HTML. SEO is supported by meta tags and Open Graph data, enhancing social media sharing and search engine visibility. The lack of CMS identification suggests a custom or proprietary platform. Hosting provider details are not discernible from the 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.
