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

CEA-Leti is a prominent French government research institute specializing in micro and nanotechnologies, focusing on applied research and innovation in wireless communication systems, biology and health, imaging, and micro-nano systems. The website reflects a well-established institution with a strong market position in technology research, supported by the Commissariat à l'Énergie Atomique et aux Énergies Alternatives (CEA). The site targets a broad audience including the general public, enterprises, journalists, and academic institutions. Technically, the website is built on Microsoft SharePoint, leveraging modern web technologies and analytics tools such as Matomo and Google reCAPTCHA for security. The security posture is solid with HTTPS enforced, though improvements could be made by adding security headers and cookie consent mechanisms. The absence of WHOIS data is noted but does not detract significantly from the site's legitimacy given its official nature and consistent branding. Overall, the site is professional, trustworthy, and serves as a comprehensive portal for CEA-Leti's research activities and partnerships.

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

9 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

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

CEA-Leti operates as an essential entity within the French research ecosystem, focusing on advanced technology sectors including energy and telecommunications. Its business model revolves around research, innovation partnerships, and technology transfer to industry. The institute maintains a strong partnership ecosystem with universities, startups, and public funders. The website content and structure indicate a mature organization with a large operational scale. Growth indicators include active participation in European programs and hosting of industry events. The presence of multiple linked domains and social media channels supports a broad outreach strategy. The lack of direct contact emails or phone numbers suggests controlled communication channels, likely to manage inquiries efficiently.

Security posture

The website demonstrates a good security posture with mandatory HTTPS and use of Google reCAPTCHA to protect forms from automated abuse. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site lacks a published incident response or vulnerability disclosure policy, which could enhance transparency and trust. GDPR compliance is supported by a comprehensive privacy policy, but the absence of a cookie consent banner indicates partial compliance. Overall, the security maturity is good but could benefit from enhanced headers and formalized security policies.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Add a cookie consent mechanism to comply fully with GDPR and enhance user privacy transparency.
  3. Publish an explicit vulnerability disclosure and incident response policy to improve security communication and trust.
  4. Enhance mobile optimization and accessibility features to improve user experience across devices.
  5. Investigate and resolve the missing WHOIS data issue to ensure domain registration transparency.

Technical notes

Notes

The website is hosted on a Microsoft SharePoint platform, indicating a robust enterprise-grade CMS infrastructure. It uses JavaScript extensively for UI and analytics, including Matomo for visitor tracking and Google reCAPTCHA for form security. The site loads multiple CSS and JS resources from internal and external sources, with moderate performance. SEO is supported by comprehensive meta tags and Open Graph data. Accessibility and mobile responsiveness are basic but functional. No critical technical debt or deprecated technologies were detected. Opportunities exist to modernize front-end frameworks and improve performance and accessibility compliance.
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.
