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

Alexion Pharmaceuticals, Inc. operates the OneSource platform to provide personalized support and education for patients undergoing treatment with Alexion therapies. The website serves as a resource hub offering treatment information, prescribing details, and access to patient education managers. It targets patients and healthcare professionals within the United States, reflecting a specialized healthcare service model. The platform is well-branded and consistent with the parent company's identity, emphasizing trust and professionalism. Technically, the website leverages a modern technology stack including Sitecore CMS, AWS hosting, Google Analytics, Facebook Pixel, and Salesforce marketing tools. It employs HTTPS with strong domain control and uses cookies responsibly with a clear consent mechanism. The site is mobile-optimized, accessible, and SEO-friendly, providing a positive user experience. From a security perspective, the site demonstrates good practices such as HTTPS enforcement, anti-CSRF tokens, and domain status protections. However, it lacks explicit security policies, vulnerability disclosure information, and some recommended security headers like Content-Security-Policy. No vulnerabilities or suspicious activities were detected. The WHOIS data aligns well with the business profile, supporting legitimacy. Overall, the website presents a low-risk profile with strong business credibility and privacy compliance. Strategic improvements include enabling DNSSEC, enhancing security headers, and publishing security and incident response policies 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

2 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. 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 Pharmaceuticals holds a strong position in the healthcare sector, focusing on rare disease treatments. The OneSource platform complements their pharmaceutical offerings by enhancing patient engagement and support, which is critical in specialty medicine markets. The business model integrates patient education and support services with pharmaceutical treatment delivery, likely improving adherence and outcomes. The company leverages partnerships with technology providers like Sitecore and Salesforce to deliver a sophisticated digital experience. The presence of multiple treatment options and prescribing information links indicates a comprehensive service portfolio. The platform's US-centric focus aligns with regulatory and market needs. Growth potential exists through expanded digital services and enhanced patient support capabilities.

Security posture

The website exhibits a mature security posture with HTTPS enforced and domain registration protections in place. Use of anti-CSRF tokens and cookie consent mechanisms indicate awareness of common web security and privacy requirements. However, the absence of a published security policy, vulnerability disclosure program, and some security headers (e.g., Content-Security-Policy) represent gaps that could be addressed. No exposed sensitive data or vulnerable libraries were detected. The site does not appear to have incident response contact information publicly available, which is a best practice for transparency and rapid response. Overall, the security posture is good but could be improved with formalized policies and enhanced header configurations.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish a comprehensive security policy and vulnerability disclosure page.
  3. Add Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options headers to strengthen browser security.
  4. Publish incident response contact information to improve transparency and readiness.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is built on a robust technical foundation using Sitecore CMS hosted on AWS infrastructure, leveraging Elastic Load Balancing for scalability and reliability. It integrates modern analytics and marketing tools such as Google Analytics, Facebook Pixel, and Salesforce, enabling data-driven insights and targeted marketing. The site is mobile-optimized and accessible, with good SEO practices evident in meta tags and structured content. Performance is moderate, likely influenced by the use of multiple third-party scripts. There is an opportunity to optimize loading times and reduce technical debt by auditing and streamlining scripts. Security headers could be enhanced to reduce attack surface. Overall, the technical implementation supports business goals effectively with room for incremental improvements.
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.
