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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  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

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.

Business context

Business profile

DNV operates in multiple sectors including energy, transportation, maritime, and healthcare, providing certification and risk management services. Their business model is service-oriented, focusing on assurance and advisory. The company leverages a global network with regional subsidiaries, as evidenced by multiple country-specific domains. Their competitive advantage lies in their comprehensive certifications (ISO 9001, ISO 14001, ISO 27001) and strong brand reputation. Revenue streams likely include certification fees, consulting services, and risk management solutions. The target customer segments are large enterprises and organizations requiring compliance and sustainability assurance. The company uses advanced marketing and analytics tools such as Qualtrics and Optimizely to optimize customer engagement and feedback. Growth indicators include a broad international presence and continuous digital modernization.

Security posture

DNV demonstrates a high level of security maturity with enforced HTTPS, comprehensive security headers, and consent-based cookie management. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the absence of a public vulnerability disclosure policy and incident response contact information indicates a gap in transparency and readiness for security incidents. Compliance with GDPR is evident through privacy and cookie policies and consent mechanisms. The use of third-party analytics and marketing tools is managed with user consent, reducing privacy risks. Overall, the security posture is robust but could be enhanced by formalizing vulnerability disclosure and incident response processes.

Recommendations

  1. Publish a public vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  2. Provide clear incident response contact information on the website to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance privacy compliance by detailing data retention policies and user rights more explicitly.
  5. Implement continuous security awareness and training programs to maintain a strong security culture.

Notes

The website uses a modern technology stack including VideoJS for media playback, Brightcove for video hosting, Google Tag Manager for tag management, Microsoft Application Insights for telemetry, and OneTrust for consent management. The CMS appears to be custom or enterprise-grade, supporting multi-language and multi-region content delivery. Performance is moderate with good mobile optimization and accessibility features. SEO is well implemented with comprehensive meta tags, Open Graph, and JSON-LD structured data. The site employs advanced consent management and analytics tools, indicating a mature digital marketing strategy. Technical risks are minimal but include reliance on multiple third-party scripts which require ongoing security monitoring.
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.
