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

ČEPS, a.s. is the exclusive operator of the Czech Republic's electricity transmission system, responsible for the safe and reliable transmission of electricity from producers to distributors and maintaining system balance. The company operates a significant infrastructure including 45 substations and approximately 6,000 kilometers of high voltage lines. It actively collaborates with European transmission system operators and contributes to the development of the electricity market. The website reflects a mature digital presence with modern technologies, responsive design, and comprehensive corporate information. Privacy and cookie consent mechanisms are well implemented, indicating compliance with GDPR requirements. Security posture is good with HTTPS enforced and no visible vulnerabilities, though some security headers and incident response information could be improved. The absence of WHOIS data limits domain registration trust analysis but does not detract from the professional presentation and transparency of the company. Overall, ČEPS demonstrates a strong market position as a critical energy infrastructure operator with a well-maintained online presence.

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

6 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

  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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

ČEPS holds a monopoly position as the national transmission system operator in the Czech energy sector, providing essential services for electricity transmission and system balancing. Its business model is focused on infrastructure operation and market facilitation, with revenue likely derived from regulated transmission tariffs. The company targets energy producers, distributors, partners, and the general public, including job seekers. The presence of a subsidiary, ČEPS Invest, indicates diversification or investment activities. The website's detailed sections on operations, regulatory compliance, and public information reflect a transparent and regulated business environment. Partnerships with European entities and participation in market coupling initiatives highlight strategic integration in the regional energy market. The company’s digital ecosystem supports stakeholder engagement and regulatory disclosures, reinforcing its credibility and operational maturity.

Security posture

The website employs HTTPS with a presumably strong SSL configuration, uses cookie consent with opt-in for analytics, and avoids exposing sensitive data in the HTML. However, no explicit security headers (e.g., CSP, HSTS) were detected in the provided data, and there is no visible security.txt or incident response contact information. The use of Google Analytics is controlled via consent, aligning with privacy best practices. The absence of WHOIS data is a minor concern but likely due to registry policies rather than malicious intent. Overall, the security posture is solid for a corporate website but could be enhanced by adding security headers, publishing a vulnerability disclosure policy, and providing incident response contacts.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve transparency.
  3. Add a dedicated incident response or security policy page with contact channels for security issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance WHOIS data availability or provide domain registration transparency to improve trust.

CookieConsent scripts manage user consent for cookies and analytics. The site is mobile-optimized with good accessibility and SEO practices evident from meta tags and structured navigation. Performance is moderate, likely influenced by external resources such as Google Fonts and video embeds. No CMS was explicitly detected, suggesting a custom or proprietary platform.

Overall, the technical infrastructure supports a professional and user-friendly experience with opportunities for performance optimization and enhanced security configurations.
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.
