Medium risk. 3 critical or high findings in Security headers and GDPR outside view.

Security score

Risk levelMedium

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

Naval Group is a leading European naval defence company serving over 50 navies worldwide. The company specializes in the design, construction, integration, and support of submarines and surface ships, positioning itself as an international player in the naval defence sector. The website reflects a mature business with comprehensive content targeting customers, candidates, journalists, suppliers, and employees. Technically, the site is built on Drupal 10 with modern JavaScript libraries and includes a cookie consent mechanism and Matomo analytics for user tracking. However, the absence of a valid SSL certificate and lack of modern TLS protocols significantly weaken the security posture. No advanced security headers or session management features are implemented, exposing the site to potential risks. Privacy compliance is well addressed with GDPR-aligned policies and consent management. Overall, the site demonstrates strong business credibility and content quality but requires urgent security improvements to protect user data and enhance 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

3 findings rated critical or high. Fix these first.

  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.

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

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

    • 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

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

Naval Group operates in the transportation and government sectors, focusing on naval defence products and services. Its business model revolves around being an industrial contractor and integrator for warships and combat systems. The company maintains a strong international presence with a wide customer base. The website supports recruitment, supplier engagement, and media relations, indicating a comprehensive ecosystem. The presence of a CERT page and whistleblowing system suggests a commitment to security and compliance. The company leverages social media extensively for brand presence and communication. Performance issues and missing SSL certificates may impact user trust and operational efficiency.

Security posture

The website currently lacks a valid SSL certificate and does not support any TLS protocols, resulting in an insecure connection. No HTTP security headers such as HSTS or Content-Security-Policy are present. Cookie consent is implemented, and no known vulnerabilities like subdomain takeover or SSL vulnerabilities were detected. The absence of OCSP stapling and session resumption reduces security and performance. Incident response information is available via a CERT page, but no security.txt or vulnerability disclosure page was found. Overall, the security posture is weak and requires immediate remediation to meet industry standards and protect sensitive data.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS and secure user connections.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable insecure protocols to improve encryption.
  3. Implement HTTP security headers including HSTS, Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Enable OCSP stapling and session resumption to enhance SSL performance and security.
  5. Develop and publish a security.txt file and a vulnerability disclosure policy to improve transparency and security culture.
Technical notes

Notes

The website is built on Drupal 10 CMS with a modern JavaScript stack and uses Matomo for analytics and Orejime for cookie consent management. Hosting is managed via EuroDNS name servers. The site has a large page size and slow load time, indicating potential optimization opportunities. Accessibility is basic, with some ARIA roles and language attributes present. SEO is well addressed with meta tags and Open Graph data. However, the lack of SSL and security headers is a critical technical deficiency. The site includes multiple forms for search, candidate login, and supplier applications, indicating active data collection. Overall, the technical infrastructure is modern but requires security and performance improvements.
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.
