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

Alexion is a well-established pharmaceutical company specializing in rare disease therapies and research, operating as part of AstraZeneca Rare Disease. The website reflects a mature enterprise with a clear focus on delivering innovative treatments and patient support services globally. The content is professionally presented, targeting patients, caregivers, healthcare professionals, and researchers. Technically, the site uses modern web technologies, including Google Tag Manager and AWS DNS infrastructure, and is likely built on the Sitecore CMS platform. The website is mobile-optimized and accessible, with good SEO practices evident. Security posture is solid with HTTPS and domain protections, though improvements such as enabling DNSSEC and adding security headers are recommended. Privacy compliance is weak on the main page, lacking explicit privacy and cookie policies, which should be addressed to meet GDPR and other regulations. Overall, the domain registration data supports the legitimacy and trustworthiness of the business.

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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

Alexion holds a strong market position in the rare disease pharmaceutical sector, leveraging AstraZeneca's global presence. Its business model centers on research and development, patient-centric services, and innovation in diagnostics and genomics. The company targets a specialized audience, including patients with rare diseases and healthcare providers. The website's structure and content indicate a focus on transparency and engagement, with multiple regional domains supporting global operations. Partnerships and parent company affiliations are clearly indicated, enhancing credibility. The absence of direct contact emails or phone numbers suggests a controlled communication approach, likely to manage inquiries efficiently.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and domain status flags preventing unauthorized changes. However, the lack of DNSSEC and missing security headers such as Content-Security-Policy and X-Frame-Options represent areas for enhancement. No vulnerability disclosures or incident response contacts are published, which could hinder rapid response to security incidents. The use of Google Tag Manager introduces moderate tracking but no evident privacy controls or cookie consent mechanisms were found, indicating potential compliance gaps. Overall, the security maturity is adequate for an enterprise but could be improved to align with best practices and regulatory requirements.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  3. Add security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  4. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Provide clear incident response contact information to improve transparency and readiness.

Technical notes

Notes

The website is built on a modern technology stack with JavaScript, CSS, and HTML5, and uses Google Tag Manager for analytics and tracking. The hosting infrastructure is supported by AWS DNS services, indicating reliable hosting. The CMS appears to be Sitecore, a robust enterprise content management system. Performance is moderate, with good mobile optimization and accessibility features. SEO is well addressed with proper meta tags and structured data in JSON-LD format. Some technical debt is noted in the absence of security headers and DNSSEC. Overall, the technical implementation supports a professional and scalable web presence.
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.
