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

2 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

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

DOF Group ASA operates in the energy and transportation sectors, providing offshore subsea and marine services. Their business model integrates multiple service lines to reduce project risk and improve efficiency for clients. The company maintains a large fleet and several subsidiaries, indicating a sizable operational footprint. Their investor relations and sustainability commitments suggest a mature organization with a focus on compliance and corporate responsibility. The website's content and structure support clear communication to investors, clients, and potential employees, reinforcing their market credibility and growth orientation.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, use of Google Tag Manager, Microsoft Clarity, and Facebook Pixel for analytics, and an ethics helpline for reporting concerns. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a dedicated security policy, incident response contact, or vulnerability disclosure program indicates areas for improvement. Implementing these would enhance transparency and readiness. The site also lacks a security.txt file, which is a modern best practice for vulnerability reporting.

Recommendations

  1. Publish a dedicated security policy and incident response information page to improve transparency.
  2. Implement a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  3. Enhance security headers explicitly, including X-Frame-Options and Referrer-Policy.
  4. Regularly audit third-party scripts and tracking tools for security and privacy compliance.
  5. Provide clearer data retention policies and privacy compliance details to strengthen GDPR adherence.

Technical notes

Notes

The website is built using Webflow CMS, leveraging modern web technologies including Google Fonts, Google Tag Manager, Microsoft Clarity, and Facebook Pixel for analytics and tracking. Hosting is via Amazon Cloudfront CDN, ensuring fast content delivery. The site is well-optimized for mobile devices and accessibility, with clean HTML and CSS. Performance is fast with asynchronous loading of scripts and deferred loading strategies. The technical implementation supports a professional user experience with clear navigation and rich content. Opportunities exist to improve security header implementation and provide more detailed technical documentation on security and privacy practices.
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.
