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 operates in the healthcare sector, specializing in plasma collection and manufacturing of life-saving therapies for rare diseases. Their business model includes plasma donor centers and global distribution of biopharmaceutical products. The website serves as a regional portal linking to global CSL Behring sites, indicating a well-integrated global network. The presence of multiple subsidiary domains for plasma collection highlights a diversified operational footprint. The target audience includes patients, healthcare professionals, and plasma donors. The company demonstrates strong branding consistency and trust signals such as privacy compliance and transparent cookie management.

Security posture

CSL Behring's website demonstrates a mature security posture with enforced HTTPS, standard security headers, and no exposed sensitive data. The use of OneTrust for cookie consent indicates compliance with privacy regulations. However, the absence of a dedicated security policy page, incident response contact information, and vulnerability disclosure mechanisms suggests room for improvement in transparency and incident readiness. No known vulnerabilities or suspicious scripts were detected. Overall, the security posture is good but could be enhanced by publishing explicit security governance documents and providing direct security contact channels.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and controls.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Include Data Protection Officer contact details to enhance GDPR transparency.
  5. Regularly review and audit third-party scripts and libraries for security vulnerabilities.

Technical notes

Notes

The website uses a modern tech stack including jQuery, Hammer.js for touch gestures, and Plyr for video playback. Google Tag Manager is employed for analytics and tracking, while OneTrust manages cookie consent and privacy compliance. The site is mobile optimized with responsive design and accessibility features such as skip links and ARIA labels. Performance is moderate with deferred script loading and optimized images. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The technical implementation supports a professional user experience with good SEO and privacy compliance.
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.
