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

No critical or high findings. These medium findings are worth fixing next.

  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.

    • Medium

      Missing Permissions-Policy header

      Controls browser features and APIs

      What to do: Implement a Permissions-Policy to restrict feature access

      • OWASP Secure Headers: OWASP Secure Headers Project recommends Permissions-Policy: accelerometer=(), autoplay=(), camera=(), cross-origin-isolated=(),…

  2. GDPR outside view

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

    • Medium

      Privacy policy may not be GDPR compliant

      Privacy policy lacks explicit GDPR compliance elements

      What to do: Update privacy policy to explicitly address GDPR requirements and user rights

  3. 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.

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

      What to do: Implement MTA-STS to prevent downgrade attacks

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Medium

      DNSSEC Not Enabled

      DNSSEC is not configured for this domain

      What to do: Enable DNSSEC to prevent DNS spoofing attacks

      • CAPEC-142
      • RFC 4033

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 operates in the healthcare sector as an essential enterprise with a focus on biopharmaceutical innovation. The company maintains a strong digital presence with dedicated investor, career, and clinical trial portals. Its business model centers on research and development of medicines, clinical trials, and corporate responsibility initiatives including STEM ecosystem support. The global reach is evident through multiple country-specific domains. The company leverages partnerships and maintains transparency through news and stories sections. The absence of explicit contact emails or phone numbers on the homepage suggests a controlled communication approach, likely directing users to specific portals. The website's content quality and branding consistency reinforce Regeneron's market leadership and credibility.

Security posture

The website demonstrates a solid security foundation with HTTPS enabled and a cookie consent mechanism via OneTrust, indicating GDPR awareness. However, no explicit security headers such as Content Security Policy, HSTS, or X-Frame-Options were detected in the provided data. There is no publicly available security policy, incident response information, or vulnerability disclosure program, which are recommended for enterprise-level organizations. No exposed sensitive data or vulnerable libraries were identified. The absence of WHOIS data is a minor concern but likely due to registry privacy or data unavailability rather than malicious intent. Overall, the security posture is good but could be enhanced by publishing security policies and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan accessible on the website.
  2. Add standard security HTTP headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Provide a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Publish a clear privacy policy and terms of service pages linked prominently from the homepage to improve privacy compliance transparency.
  5. Consider including verified company contact emails and phone numbers for improved user trust and communication.

Technical notes

Notes

The website is built on a modern technology stack including Google Tag Manager for analytics and marketing, jQuery for scripting, OneTrust for cookie consent management, and Vimeo for video hosting. The CMS appears to be Kentico, a robust enterprise content management system. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate, with asynchronous loading of scripts and multimedia content. SEO is well addressed with proper meta tags, Open Graph data, and structured JSON-LD for rich snippets. There is room for improvement in security header implementation and explicit hosting provider identification. Overall, the technical infrastructure 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.
