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

Sanofi is a globally recognized, research and development-driven biopharmaceutical company leveraging artificial intelligence to innovate in healthcare. The company focuses on developing medicines and vaccines across multiple therapeutic areas, positioning itself as a leader in the healthcare industry with a strong commitment to improving patient outcomes. The website reflects a mature enterprise with comprehensive content targeting healthcare professionals, patients, investors, and partners. Technically, the site employs modern frameworks and libraries such as Material UI and Font Awesome, with integrations for analytics and cookie consent management. However, the security posture is currently weak due to the absence of a valid SSL/TLS certificate and missing security headers, which poses significant risks for user trust and data protection. Privacy compliance is well addressed with clear policies and consent mechanisms, aligning with GDPR requirements. Overall, while the business credibility and content quality are high, urgent improvements in security infrastructure are recommended to enhance trust and protect users.

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

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

Sanofi operates as a large enterprise in the healthcare sector, specializing in pharmaceuticals and vaccines with a strong R&D and AI focus. The company maintains a robust online presence with detailed information on its pipeline, scientific collaborations, and sustainability initiatives. Its business model revolves around innovation, clinical development, and global distribution of healthcare products. The presence of a subsidiary, Opella, indicates diversification within consumer healthcare. The website's content and structure support investor relations and partner engagement, reflecting a mature and well-established market position. Strategic partnerships and a global footprint are evident, supporting growth and competitive advantage in the biopharma industry.

Security posture

The current security posture of the website is inadequate, primarily due to the lack of a valid SSL/TLS certificate, resulting in no HTTPS support. This exposes users to potential data interception and undermines trust. Additionally, the absence of security headers such as HSTS, Content-Security-Policy, and X-Frame-Options further weakens the site's defenses against common web attacks. No evidence of incident response policies or security certifications was found on the site. While privacy policies and cookie consent mechanisms are in place, the fundamental transport layer security must be addressed immediately to comply with best practices and regulatory requirements.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement security headers including HSTS, Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Enable OCSP stapling to improve certificate revocation checking performance and security.
  4. Publish a security policy and incident response contact information to enhance transparency and readiness.
  5. Conduct regular security audits and vulnerability assessments to identify and remediate risks proactively.
Technical notes

Notes

The website is built using modern web technologies including Material UI and Font Awesome for UI components and icons. Google Tag Manager is used for analytics and tracking, alongside OneTrust for cookie consent management, indicating compliance with privacy regulations. Hosting appears to be on Amazon AWS infrastructure, supported by multiple IP addresses. Performance is suboptimal with a load time of approximately 19 seconds, which may impact user experience. The site is mobile optimized and SEO friendly with proper meta tags and Open Graph data. Accessibility features are basic but present. Technical debt is indicated by the lack of SSL and security headers, which should be prioritized for remediation to avoid business risks.
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.
