Nederlandse Aardolie Maatschappij (NAM) is a well-established Dutch energy company specializing in the exploration, development, and production of oil and gas from the Dutch subsurface. Founded in 1947 by Shell and Esso, NAM plays a significant role in supplying energy to Dutch society and industry, with a strong focus on safety, environmental responsibility, and contributing to the energy transition. The website reflects a mature digital presence with comprehensive content, clear navigation, and consistent branding, targeting stakeholders interested in energy production and sustainability in the Netherlands. Technically, the website is built on Adobe Experience Manager, leveraging modern web technologies such as ES modules and CSS variables. It demonstrates good mobile optimization, accessibility, and SEO practices, although performance is moderate. Security posture is solid with HTTPS enforced and no visible vulnerabilities, but could be improved by adding explicit security headers and publishing formal security policies. Privacy compliance is well addressed with clear privacy and cookie policies, including consent mechanisms aligned with GDPR. Contact information is available primarily via a contact form, and social media channels are actively linked. WHOIS data confirms the domain's legitimacy and consistency with the company's identity.

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. 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

  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.

    • 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

NAM holds a strong market position as a key player in the Dutch energy sector, with a business model focused on oil and gas exploration and production, complemented by underground gas storage and sustainability initiatives. Its founding by major energy companies Shell and Esso underscores its strategic importance. The company targets Dutch society and industry stakeholders, emphasizing innovation and safety. The website content and linked social media channels indicate active engagement and transparency. The partnership with Shell is a critical element of its ecosystem. Growth indicators include ongoing energy transition efforts and divestment of offshore assets to Tenaz Energy. The business model relies on long-term energy supply and adaptation to climate challenges.

Security posture

The website exhibits a mature security posture with HTTPS enforced and no exposed sensitive data. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security or incident response policies represent gaps. No vulnerability disclosure or security.txt files were found, limiting external reporting channels. The use of Adobe Experience Manager suggests enterprise-grade infrastructure, but security best practices could be enhanced. Privacy policies and cookie consent mechanisms are well implemented, supporting GDPR compliance. Overall, the security maturity is good but can be improved by formalizing security policies and enhancing header configurations.

Recommendations

  1. Implement and publish a formal security policy and incident response plan on the website.
  2. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen browser security.
  3. Publish a security.txt file to facilitate vulnerability disclosure and improve transparency.
  4. Enhance visibility of data protection officer contact information to support GDPR compliance.
  5. Regularly review and update third-party scripts and tracking tools to minimize privacy risks and improve performance.

Technical notes

Notes

The website is built on Adobe Experience Manager, indicating a robust CMS platform suitable for enterprise needs. It uses modern JavaScript modules and CSS variables for styling, supporting responsive and accessible design. Performance is moderate, with room for optimization in image loading and script management. SEO is well addressed with proper meta tags and Open Graph data. Accessibility features such as skip links and semantic HTML are present. Hosting provider details are not explicit, but the infrastructure appears stable. Technical risks are minimal, though adding security headers and optimizing performance could reduce potential attack surface and improve user experience.
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.
