Risk levelMedium

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

CSL Plasma Deutschland operates in the healthcare sector focusing on the collection, testing, and storage of human blood plasma. The website presents a professional and consistent brand image targeted at a general audience in Germany. The business model revolves around plasma services, but detailed business information such as company founding year or parent company is not disclosed. Technically, the website employs modern tools like Google Tag Manager and OneTrust for cookie consent, hosted likely via AT&T infrastructure. The site is moderately optimized for performance and mobile use, with basic accessibility and SEO features. Security posture is adequate with HTTPS implied and cookie consent implemented, but lacks visible security headers and published security policies. Privacy compliance is partial due to the absence of a clear privacy policy and terms of service. WHOIS data is minimal, limiting trust analysis but no suspicious patterns are detected. Overall, the website is functional and professional but would benefit from enhanced transparency and security documentation.

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 Plasma Deutschland is positioned as a healthcare service provider specializing in plasma-related services. The company targets individuals and healthcare stakeholders in Germany. The business model likely includes plasma collection centers and related medical services. The website's integration with OneTrust and Google Tag Manager indicates awareness of privacy and analytics needs. However, the lack of detailed business and contact information online may limit customer trust and engagement. There is no evidence of partnerships or subsidiaries from the provided data. The company appears to maintain a moderate digital presence with room for growth in transparency and compliance disclosures.

Security posture

The website demonstrates a basic security posture with HTTPS usage and a cookie consent mechanism via OneTrust. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and others reduces the overall security robustness. No security policy, incident response contacts, or vulnerability disclosure information is published, which may hinder incident management and trust. The WHOIS data lacks registrant details, which slightly impacts domain trustworthiness. No vulnerabilities or exposed sensitive data were detected in the provided content. The security score is moderate, with recommendations to publish security policies, improve header configurations, and provide clear incident response contacts.

Recommendations

  1. Publish a comprehensive privacy policy page clearly accessible from the website.
  2. Add terms of service and security policy documents to enhance transparency.
  3. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  4. Provide clear contact information including emails and phone numbers for general and security-related inquiries.
  5. Consider publishing a security.txt file and vulnerability disclosure policy to improve security posture and trust.

Technical notes

Notes

The website uses modern web technologies including Google Tag Manager for analytics and OneTrust for cookie consent management. The presence of VideoJS player styles indicates multimedia content support. Hosting appears to be via AT&T infrastructure based on nameservers. The site is moderately optimized for performance and mobile responsiveness, with basic SEO and accessibility features. However, no CMS or specific frameworks were detected. The site could improve by enhancing accessibility compliance and adding structured data for better SEO. Technical debt appears low but transparency and security documentation are lacking.
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.
