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

NVL B.V. & Co. KG is a well-established, independent group of northern German shipyards specializing in naval and coastguard vessel construction and related maritime services. With over 145 years of experience, NVL serves a global clientele including the German Navy and fleets in more than 50 countries. Their comprehensive service portfolio spans new builds, maintenance, repair, upgrades, and digital transformation, supported by a network of four shipyards and multiple international subsidiaries. The company emphasizes quality, innovation, and customer-centric solutions, positioning itself as a leader in the naval shipbuilding industry. Technically, the NVL website is built on Drupal 10, leveraging modern web technologies including jQuery and FontAwesome, and is hosted on AWS infrastructure. The site is mobile-optimized, accessible, and employs privacy-conscious analytics via Matomo alongside a robust cookie consent mechanism. The digital presence reflects a mature and professional infrastructure with good SEO and user experience. From a security perspective, the site enforces HTTPS and uses cookie consent tools to comply with GDPR. However, explicit security policies and incident response contacts are not prominently published, and security headers are not visibly configured. No vulnerabilities or exposed sensitive data were detected. The WHOIS data aligns with the business claims, showing consistent domain registration and DNS setup. Overall, NVL demonstrates a strong business credibility and digital maturity with a secure and privacy-aware web presence. Strategic improvements in publishing security policies and enhancing security headers would further strengthen their security posture.

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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

NVL holds a strong market position as a legacy shipbuilding group with a diversified service offering and international subsidiaries. Their business model focuses on manufacturing, maintenance, and lifecycle services for naval and coastguard vessels, targeting government and defense sectors globally. The company leverages its heritage and innovation to maintain competitive advantages. The website indicates a well-established partnership ecosystem and a clear growth strategy through international operations. Revenue streams likely include new builds, service contracts, and technology transfer arrangements. The professional digital presence supports their market credibility and customer engagement.

Security posture

NVL's security posture is solid with mandatory HTTPS and GDPR-compliant cookie consent mechanisms. The use of Matomo analytics reflects a privacy-conscious approach. However, the absence of published security policies, incident response contacts, and security headers suggests room for improvement in transparency and defense-in-depth. No critical vulnerabilities or data exposures were found, indicating a low immediate risk. Enhancing security documentation and technical controls would improve incident readiness and trust.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide explicit incident response contact emails (e.g., security@ or abuse@) on the website.
  4. Implement and publish a vulnerability disclosure policy or security.txt file.
  5. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern Drupal 10 CMS with a clean and responsive design optimized for mobile devices. Hosting on AWS DNS infrastructure ensures reliability and scalability. The tech stack includes jQuery, FontAwesome, and Matomo analytics, indicating a balance between modern features and privacy. Performance is moderate with room for optimization. Accessibility and SEO are well addressed. The site uses external consent management scripts for GDPR compliance. No technical debt or major risks were identified, but adding security headers and improving incident response visibility would enhance the technical robustness.
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.
