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

Valneva is a specialty vaccine company focused on the development, manufacturing, and commercialization of prophylactic vaccines addressing infectious diseases with unmet medical needs. The company has a strong market position with multiple commercialized vaccines and a robust pipeline targeting diseases such as chikungunya, Lyme disease, Shigella, and Zika. The website reflects a professional corporate presence with comprehensive investor relations and media resources, targeting healthcare professionals, investors, and partners globally. Technically, the website is built on WordPress with modern SEO and marketing tools, including Google Tag Manager and social media integrations. However, the security posture is weakened by an invalid SSL certificate and lack of TLS protocol support, which poses significant risks to data confidentiality and user trust. Privacy compliance is well addressed with clear privacy and cookie policies and consent mechanisms. Overall, the site is professional and credible but requires urgent remediation of SSL/TLS issues to improve security and trust.

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

4 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 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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

Valneva operates in the healthcare sector specializing in vaccines, leveraging its expertise to commercialize products and advance clinical candidates. The company targets a global audience including healthcare providers and investors, supported by regional subsidiaries in multiple countries. Its business model integrates vaccine R&D, manufacturing, marketing, and distribution. The website's content and structure support strong branding consistency and trust signals such as corporate governance and investor information. The company benefits from a broad partnership ecosystem and active social media presence, indicating a mature market position and growth orientation.

Security posture

The current security maturity level is moderate to low due to critical SSL/TLS configuration issues. While security headers such as HSTS, X-Frame-Options, and Content-Security-Policy are present, the invalid SSL certificate and disabled TLS protocols undermine secure communications. No explicit incident response or security policy pages were found, indicating potential gaps in transparency and readiness. The site uses secure forms but lacks advanced security features like OCSP stapling and session resumption. Compliance with GDPR is supported by privacy and cookie policies with consent mechanisms. Immediate remediation of SSL/TLS issues is critical to reduce business risk and protect user data.

Recommendations

  1. Immediately renew and deploy a valid SSL certificate to enable HTTPS securely.
  2. Enable and configure TLS 1.2 and TLS 1.3 protocols to ensure modern encryption standards.
  3. Implement OCSP stapling and session resumption to improve security and performance.
  4. Publish explicit security and incident response policies to enhance transparency and trust.
  5. Regularly audit and update security headers and Content Security Policy for comprehensive protection.
Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, FontAwesome, GSAP, and Google Tag Manager. SEO is enhanced by Yoast SEO plugin, and user experience is supported by responsive design and accessibility features. Performance metrics were not available, but the site uses common CDN resources for assets. The technical infrastructure is standard for corporate websites but requires security upgrades. Hosting details are not explicit but DNS and server headers indicate Apache server with a single IPv4 address. The site uses multiple plugins for forms, cookie management, and social media integration, reflecting a mature digital presence with some technical debt related to SSL/TLS configuration.
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.
