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

1 finding rated critical or high. Fix these first.

  1. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Regeneron holds a strong market position as a biotechnology leader with multiple approved drugs and ongoing R&D pipelines. The business model focuses on internal drug discovery and commercialization, supported by advanced scientific innovation and manufacturing capabilities. The website's integration with Salesforce platforms indicates a sophisticated digital ecosystem supporting customer engagement and operational efficiency. The absence of direct contact emails or phone numbers suggests a controlled communication channel via web forms, typical for regulated healthcare entities. The company maintains compliance with privacy laws and employs trusted third-party services for payments and analytics, reflecting a mature partnership ecosystem and strategic digital marketing approach.

Security posture

The website exhibits a solid security maturity level with enforced HTTPS, comprehensive Content-Security-Policy, and client-side error reporting mechanisms. The use of Cloudflare DNS and enterprise-grade registrar MARKMONITOR further enhances domain security. However, the lack of publicly available security policies, incident response plans, or vulnerability disclosure programs indicates room for improvement in transparency and readiness. No exposed sensitive data or vulnerable libraries were detected. Privacy compliance is well addressed through OneTrust cookie consent and GDPR-aligned policies. Overall, the security posture is strong but could benefit from enhanced communication of security governance and incident handling.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Add security contact channels such as security@ or abuse@ emails for direct communication.
  4. Enhance HTTP security headers by adding HSTS, X-Frame-Options, and X-Content-Type-Options.
  5. Regularly review and audit third-party scripts and dependencies to mitigate supply chain risks.

Technical notes

Notes

The website is built on Salesforce Experience Cloud using the Lightning Web Runtime framework, indicating a modern and scalable infrastructure. Integration with multiple payment providers (Stripe, PayPal, Adyen) and analytics tools (Google Analytics, Tag Manager) shows a comprehensive digital marketing and e-commerce capability. Performance is moderate with good mobile optimization and accessibility features. The site uses strict Content-Security-Policy headers to limit resource loading to trusted domains, enhancing security. Technical debt appears low, but opportunities exist to improve security headers and incident response transparency. Overall, the technical implementation supports a professional and secure user experience aligned with enterprise standards.
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.
