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

  2. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 10 days

      What to do: Renew domain registration before expiration

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 holds a dominant position in Ireland's energy sector as the designated gas network operator. Their business model centers on infrastructure management and facilitating the transition to a net-zero carbon gas network by 2045. Key revenue streams likely include network access and connection services for homes, businesses, and biomethane producers. The company actively promotes innovation and sustainability, positioning itself as a forward-looking utility. Partnerships and subsidiaries such as Aurora Telecom indicate diversification. The website's detailed corporate governance and investor relations sections suggest transparency and regulatory compliance. The presence of emergency contact numbers and safety information highlights operational responsibility and customer focus.

Security posture

Gas Networks Ireland exhibits a mature security posture with enforced HTTPS, use of Content Security Policy nonces, and secure form validation. However, the absence of publicly available security policies, incident response contacts, and vulnerability disclosure programs indicates room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the website content. The site uses third-party scripts like Google Tag Manager and Genesys chat, which should be regularly audited to mitigate supply chain risks. Overall, the security posture is strong but could benefit from enhanced communication of security practices and incident handling.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and customer trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide contact details for a Data Protection Officer or security contact to comply with GDPR and enhance trust.
  4. Enhance HTTP security headers by adding X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  5. Regularly review and audit third-party scripts and tracking tools to minimize security risks.

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.
