Slovenská elektrizačná prenosová sústava, a.s. (SEPS) is the Slovak national electricity transmission system operator responsible for managing, operating, and developing the country's transmission grid. The company provides critical services including auctions, scheduling, support services, and technical data for partners, while also engaging in public consultations and international cooperation projects. SEPS holds a significant market position as an essential energy infrastructure entity in Slovakia, serving energy market participants, partners, and the general public. The website reflects a professional and comprehensive digital presence with clear navigation and relevant content tailored to its audience. Technically, the website is built on WordPress with modern technologies such as jQuery, Swiper.js, and Google Tag Manager. It employs Google reCAPTCHA for form security and implements GDPR-compliant cookie consent mechanisms. The site is mobile-optimized and SEO-friendly, though accessibility features could be enhanced. Performance is moderate, with room for optimization. From a security perspective, SEPS demonstrates a mature posture, evidenced by ISO 27001 certification and HTTPS enforcement. Security best practices include secure forms and cookie consent, though some security headers are not explicitly confirmed. No vulnerabilities or exposed sensitive data were detected in the analyzed content. However, explicit incident response and vulnerability disclosure policies are not publicly found, representing an area for improvement. Overall, the website is trustworthy, professionally maintained, and compliant with relevant privacy regulations. The domain registration data aligns well with the business claims, reinforcing legitimacy. Strategic recommendations include enhancing security headers, publishing incident response policies, improving accessibility, and maintaining regular security audits to sustain and improve the security posture.

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

8 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

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.

Business context

Business profile

SEPS operates as a critical national transmission system operator in Slovakia's energy sector, providing essential grid management and market services. Its business model is centered on regulated infrastructure operation, offering services such as auctions, scheduling, and technical data provision. The company targets energy market participants, partners, and public stakeholders, positioning itself as an indispensable entity in Slovakia's energy market. The website content and structure indicate a focus on transparency, regulatory compliance, and stakeholder engagement through public consultations and international projects. The presence of ISO 27001 certification and GDPR compliance signals a commitment to security and data protection, which are vital in the energy sector. SEPS maintains partnerships and related domains for document management and public procurement, reflecting a well-integrated operational ecosystem.

Security posture

SEPS exhibits a strong security posture with HTTPS enforced and ISO 27001 certification in place, indicating adherence to international information security standards. The website uses Google reCAPTCHA to protect forms from automated abuse and implements GDPR-compliant cookie consent mechanisms. While some security headers are not explicitly confirmed in the provided data, the overall configuration suggests a secure environment. No exposed sensitive data or vulnerabilities were detected. However, the absence of publicly available incident response and vulnerability disclosure policies suggests an opportunity to enhance transparency and readiness. Regular updates and audits of third-party libraries and security configurations are recommended to maintain resilience against emerging threats.

Recommendations

  1. Implement and verify comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish explicit incident response and vulnerability disclosure policies to improve transparency and stakeholder trust.
  3. Enhance website accessibility features to comply with best practices and legal requirements.
  4. Conduct regular security audits and update third-party libraries to mitigate potential vulnerabilities.
  5. Maintain and promote security certifications and compliance achievements to reinforce market confidence.

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.
