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

CSL Behring Slovakia s.r.o. operates as a key player in the biopharmaceutical sector, specializing in innovative plasma-derived and recombinant therapies for rare and serious diseases. The company is part of the global CSL Limited group, maintaining a strong market position with a focus on research, development, and manufacturing of high-quality medicines. The website reflects a professional corporate presence with clear navigation and relevant content tailored to patients, healthcare professionals, and partners. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript, Google Tag Manager for analytics, and OneTrust for cookie consent management. The site is mobile-optimized and demonstrates good SEO and accessibility practices, although some accessibility features could be enhanced. Performance is moderate with no critical technical issues detected. From a security perspective, the site enforces HTTPS with appropriate security headers and implements cookie consent mechanisms aligned with GDPR requirements. However, there is no explicit security policy or incident response information publicly available, and no vulnerability disclosure or security.txt file was found. No exposed sensitive data or vulnerabilities were detected in the analyzed content. Overall, the website presents a low-risk profile with strong business credibility and compliance posture. Strategic improvements could include publishing detailed security policies, incident response contacts, and enhancing accessibility to further strengthen trust and compliance.

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

3 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

  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 Slovakia s.r.o. is positioned as a large healthcare entity within the global CSL Limited group, focusing on plasma and recombinant biopharmaceutical products. The company targets patients with rare and serious diseases, healthcare providers, and research partners. Its business model revolves around innovation, manufacturing, and distribution of specialty medicines. The website indicates a well-established brand with consistent messaging and a broad international presence through related domains. The integration of global and regional sites suggests a strong partnership ecosystem and market reach. The absence of direct contact emails or phone numbers on the main pages suggests controlled communication channels, likely to ensure compliance and data protection.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, modern security headers, and GDPR-compliant cookie consent mechanisms. The use of OneTrust for cookie management and Google Tag Manager for analytics is standard for corporate sites. However, the lack of a public security policy, incident response contacts, or vulnerability disclosure mechanisms indicates areas for improvement in transparency and readiness. No critical vulnerabilities or exposed sensitive data were found in the HTML content. The security score is good but could be enhanced by adding explicit security documentation and incident handling information.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response contact channels such as security@ or abuse@ emails.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance website accessibility features to meet higher standards.
  5. Regularly review and audit third-party scripts and tracking tools for security and privacy compliance.

Technical notes

Notes

The website is built using standard web technologies including HTML5, CSS3, and JavaScript, with integration of Google Tag Manager and OneTrust for analytics and cookie consent respectively. The site is mobile responsive and optimized for SEO with proper meta tags and Open Graph data. Performance is moderate with no major technical debt observed. The absence of a detected CMS suggests a custom or proprietary platform. Hosting provider details were not identified. The site uses Plyr for video playback, indicating multimedia support. Overall, the technical infrastructure supports a professional corporate website with room for modernization in accessibility and security transparency.
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.
