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

The website supports Alexion's business model focused on rare disease pharmaceuticals, providing patient-centric services including education, support programs, and regulatory compliance information. Market positioning is strong in the niche of rare diseases with FDA-approved treatments. The site integrates with related domains for healthcare professionals and REMS programs, indicating a comprehensive ecosystem. Revenue streams likely include pharmaceutical sales supported by patient adherence programs. The partnership ecosystem includes specialized marketing and analytics providers. Growth indicators include ongoing updates and a pregnancy registry study. Strategic observations highlight the importance of maintaining regulatory compliance and patient trust through transparent communication and support.

Security posture

The security maturity level is moderate to high, with HTTPS enforced and domain status protections in place. The absence of DNSSEC and some security headers suggests room for improvement. No vulnerabilities or exposed sensitive data were detected. Compliance with REMS program requirements and patient safety warnings indicates strong regulatory adherence. However, the lack of a public security policy or incident response contact limits transparency. Data protection practices appear adequate with cookie consent and privacy policies aligned with GDPR. Incident response readiness cannot be fully assessed due to missing information. Overall, the security posture supports business continuity but would benefit from enhanced transparency and technical controls.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures.
  3. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve browser security.
  4. Provide explicit contact channels for security incidents, such as security@ or abuse@ email addresses.
  5. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern technology stack including Bootstrap 5, jQuery 3.6, Google Tag Manager, and Sitecore CMS, hosted on AWS infrastructure. Performance is moderate with good mobile optimization and accessibility features. SEO is supported by proper meta tags and Open Graph data. Cookie management is handled via Digital Control Room, ensuring compliance with privacy regulations. The site integrates multiple third-party advertising and analytics services with user consent. Technical debt appears low, but enabling DNSSEC and adding security headers would reduce risk. The infrastructure supports a professional and scalable digital presence suitable for healthcare industry requirements.
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.
