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 d.o.o. holds a niche position in the maritime transportation sector, leveraging its parent company NVL B.V. & Co. KG's heritage and network. The company targets government and defense maritime clients, focusing on naval and coast guard vessels. Their competitive advantage lies in combining innovation with traditional shipbuilding expertise and a strong commitment to sustainability and corporate social responsibility. Revenue streams likely include design, consulting, and program management services. The company maintains a supplier network and uses portals for partner engagement, indicating a mature partnership ecosystem. Growth indicators include recent domain registration aligned with company founding and active recruitment efforts. Strategic observations highlight a focus on technological progress and international collaboration.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, anti-bot JavaScript, and a cookie consent mechanism compliant with GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy and Strict-Transport-Security suggests room for improvement. There is no published security policy or incident response contact information, which could enhance transparency and readiness. The site lacks a security.txt file for vulnerability disclosure. Overall, the security maturity is good but could be elevated by adopting additional best practices and formalizing incident response channels.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures.
  3. Add a security.txt file at the root domain to facilitate vulnerability reporting.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance transparency by providing clear contact channels for security incidents and abuse reports.

Technical notes

Notes

The website is built on Drupal 10 CMS, leveraging modern JavaScript libraries such as jQuery and Slick Carousel for UI components. Analytics are handled via Matomo, a privacy-focused platform, integrated with a Cookiefirst consent banner ensuring GDPR compliance. The site is mobile-optimized with responsive images and accessible navigation. Hosting appears to be managed under Croatian registrar CARNET, consistent with the company's location. Performance is moderate, with potential improvements in caching and resource optimization. The technical stack is modern and well-maintained, though security headers and formal vulnerability disclosure mechanisms are absent, representing technical debt and risk areas.
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.
