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

7 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The company operates in the energy and transportation sectors, focusing on natural gas transmission and LNG services. It targets industry participants such as gas transport users and regulatory authorities. The business model revolves around infrastructure operation, service provision, and compliance with EU and national regulations. The website reveals a mature digital presence with detailed corporate governance, compliance policies, and service descriptions. The absence of public vulnerability disclosure and incident response contacts suggests room for improvement in transparency. The company holds ISO 27001 certification, indicating a commitment to information security management. The website's content and structure support a large enterprise profile with a strong emphasis on regulatory adherence and stakeholder communication.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and multiple security headers implemented, including HSTS and CSP. Cookie consent is managed via OneTrust, supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The use of security-related plugins such as miniorange OAuth SSO indicates attention to secure authentication. However, the lack of a public vulnerability disclosure policy and incident response contact channels limits the site's security transparency. Regular audits of third-party plugins and enhanced monitoring of form inputs are recommended to maintain security integrity. Overall, the site aligns well with best practices but could enhance its security culture by publishing incident response information.

Recommendations

  1. Publish a security.txt file or vulnerability disclosure policy to encourage responsible reporting.
  2. Provide clear incident response contact information on the website.
  3. Conduct regular security audits of third-party plugins and dependencies.
  4. Enhance form input validation and monitoring to prevent injection attacks.
  5. Maintain and publicize security certifications and compliance achievements.

Technical notes

Notes

The website is built on WordPress, leveraging popular plugins such as Yoast SEO Premium for SEO optimization, Contact Form 7 for forms, and OneTrust for cookie consent management. It uses jQuery and Google Fonts for frontend functionality and styling. The site is mobile optimized with responsive design and accessibility features such as skip links and focus outlines. Performance is moderate, with potential for improvement in loading speed. SEO is well implemented with proper meta tags, Open Graph data, and JSON-LD structured data. The technical stack is modern and appropriate for a corporate site, though hosting provider details were not identified. The site demonstrates good technical hygiene but could benefit from performance tuning and enhanced security transparency.
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.
