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

15 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: Telnet

      Port 23 (Telnet) is publicly accessible - Telnet - Unencrypted remote access

      What to do: Immediately restrict access to Telnet using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: MSSQL

      Port 1433 (MSSQL) is publicly accessible - MSSQL - Database server

      What to do: Immediately restrict access to MSSQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 · found on this site
  • 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

DNV Cyber leverages its parent company DNV AS's reputation and subsidiaries like Nixu to offer comprehensive cybersecurity services tailored to critical infrastructure industries. Their business model focuses on consulting, risk assessment, compliance guidance, and incident response, addressing evolving cyber threats. The company targets large enterprises in energy, maritime, and manufacturing sectors, emphasizing regulatory compliance and operational technology security. The website content and customer stories highlight successful partnerships and projects, indicating strong market traction and growth potential. The integration of advanced analytics and consent management tools reflects a mature digital strategy aligned with privacy regulations. Strategic partnerships and a clear service portfolio position DNV Cyber as a key player in European cybersecurity services.

Security posture

The website exhibits a mature security posture with enforced HTTPS, use of secure video streaming technologies, and integration of cookie consent mechanisms compliant with GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security policy documentation and vulnerability disclosure mechanisms suggests areas for improvement. Incident response services are prominently featured, indicating operational readiness. The use of modern analytics and consent tools supports privacy and security compliance. Recommendations include publishing detailed security headers, establishing a public vulnerability disclosure policy, and providing direct security contact channels to enhance transparency and trust.

Recommendations

  1. Publish explicit security headers such as Content-Security-Policy and X-Frame-Options to strengthen browser security.
  2. Create and maintain a public vulnerability disclosure or security.txt file to facilitate responsible reporting.
  3. Add direct security contact emails (e.g., security@dnv.com) to improve incident reporting and communication.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance transparency by publishing a detailed security policy outlining frameworks and certifications.

Technical notes

Notes

The website is built using modern web technologies including React for frontend components, Brightcove for video delivery, and integrates analytics via Google Tag Manager and Azure Application Insights. The CMS appears to be Episerver, supporting structured content management. Performance is moderate with optimized images and responsive design ensuring good mobile experience. Accessibility features such as skip links and ARIA labels are present, enhancing usability. The site employs OneTrust for cookie consent management, ensuring compliance with privacy regulations. Technical risks are minimal, but opportunities exist to improve security headers and formalize vulnerability disclosure processes to reduce potential attack surface and increase stakeholder trust.
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.
