0–100, higher is better. How it is calculated

ELES, d. o. o. is the exclusive public operator of the combined transmission and distribution electricity network in Slovenia, established in 1996. The company operates the national transmission grid and provides system services, development, and maintenance of the electricity infrastructure. Their website is targeted at business users and public entities involved in the Slovenian energy sector. The site is built on the DotNetNuke CMS platform, uses Cloudflare DNS services, and integrates Google Analytics for user tracking. The content is primarily in Slovenian and includes comprehensive information about projects, network operation, and regulatory compliance. Security-wise, the site uses HTTPS and cookie consent mechanisms but lacks explicit security headers and incident response contact details. Overall, the domain's WHOIS data confirms a long-standing and legitimate registration consistent with the company's public service role.

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.

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

ELES holds a strong market position as the sole system operator of Slovenia's transmission electricity network. Their business model is focused on public service provision, infrastructure development, and international energy projects. The website reflects a mature digital presence with structured navigation and relevant content for stakeholders. Partnerships with entities like SODO (distribution network operator) are evident. The company benefits from a stable domain registration and consistent branding. Revenue streams likely derive from regulated network operation fees and system services. Growth indicators include ongoing infrastructure projects and participation in international initiatives.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and a cookie consent banner in place, indicating compliance with privacy regulations. However, the absence of visible security headers such as Content-Security-Policy and lack of published incident response or vulnerability disclosure policies suggest room for improvement. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The use of third-party scripts like Google Analytics introduces moderate tracking but is standard for such sites. Overall, the security maturity is adequate for a public utility but could be enhanced by adopting best practices and transparency measures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Conduct regular audits of third-party scripts and dependencies to identify and remediate vulnerabilities.
  4. Enhance mobile optimization and accessibility features to improve user experience across devices and for users with disabilities.
  5. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.

Technical notes

Notes

The website is built on the DotNetNuke CMS framework, utilizing Telerik UI components and jQuery libraries. Hosting is supported by Cloudflare DNS services, enhancing availability and DNS security. The site loads asynchronously Google Tag Manager and Google Analytics scripts for tracking. Performance is moderate with room for optimization, especially in mobile responsiveness and accessibility. The HTML structure is valid with appropriate meta tags for SEO. There is no evidence of outdated or vulnerable libraries in the provided content. Technical debt appears low, but modernization opportunities exist in security and mobile UX enhancements.
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.
