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

CSL Behring España is a healthcare-focused biopharmaceutical company specializing in innovative therapies for rare and serious diseases. The website presents a professional and well-structured digital presence, targeting patients, healthcare professionals, and stakeholders in Spain. The company emphasizes corporate responsibility, patient community involvement, and research and development as core aspects of its business model. The site is branded consistently with the global CSL Behring identity, reflecting its position as a global leader in its sector. Technically, the website employs modern technologies including Google Tag Manager for analytics, OneTrust for cookie consent management, and Brightcove for media playback. The site is mobile-optimized and accessible, with good SEO practices evident from meta tags and structured navigation. However, explicit CMS or hosting provider details are not discernible from the provided data. From a security perspective, the site uses HTTPS and implements cookie consent mechanisms, indicating a baseline compliance with privacy regulations such as GDPR. However, no explicit security headers were detected, and no published security or incident response policies were found. The WHOIS data is restricted by the .es registry policies, which is typical and does not raise immediate concerns. Overall, the security posture is moderate but could be improved with additional headers and transparency. The overall risk assessment is low, with recommendations to enhance privacy policy visibility, security header implementation, and contact information clarity to improve trust and compliance. The website is suitable for its audience and business purpose, with no indications of malicious or suspicious activity.

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 operates in the healthcare sector with a focus on rare and serious diseases, positioning itself as a global leader. The business model centers on research, development, and provision of innovative therapies, supported by patient engagement and corporate responsibility initiatives. The website content and structure reflect a mature organization with a large operational scale in Spain, likely part of the global CSL Limited group. The absence of explicit revenue or financial data is typical for corporate websites. The company leverages digital tools for marketing and compliance but does not expose sensitive business details publicly. The partnership ecosystem is not explicitly detailed, and no subsidiary domains were identified. The site serves as a key communication channel for patients, professionals, and partners, supporting brand reputation and market presence.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and a cookie consent mechanism in place, indicating awareness of privacy and security compliance requirements. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for improvement in hardening the site against common web attacks. No exposed sensitive data or vulnerable libraries were detected in the provided content. The absence of a published security policy or incident response contact reduces transparency and may impact stakeholder trust. GDPR compliance indicators are partial, with cookie consent but no explicit privacy policy found. Overall, the security posture is adequate for a corporate informational site but should be enhanced to meet best practices and regulatory expectations fully.

Recommendations

  1. Implement and publish a comprehensive privacy policy page clearly accessible from the homepage.
  2. Add essential security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to improve site security.
  3. Provide explicit contact information for security and privacy inquiries, including a dedicated security or abuse email address.
  4. Publish a security policy and incident response plan summary to increase transparency and stakeholder confidence.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern tech stack with Google Tag Manager for analytics, OneTrust for cookie consent, and Brightcove for video content delivery. The HTML structure is well-formed with meta tags supporting SEO and social media sharing (Open Graph and Twitter cards). The site is mobile-optimized and includes accessibility features such as skip links and ARIA labels. No explicit CMS or hosting provider was identified. Performance appears moderate based on included scripts and resources. The site uses canonical URLs and consistent branding assets. Technical debt is minimal from the visible content, but the absence of security headers and explicit privacy documentation suggests areas for modernization and compliance enhancement.
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.
