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. The company maintains and develops a high-voltage grid infrastructure spanning approximately 6,000 kilometers and collaborates with other European transmission system operators to support market development and grid stability. The website reflects a mature digital presence with professional design, clear navigation, and compliance with privacy regulations including GDPR. Technically, the site uses modern web technologies such as Bootstrap, AnyChart, and Google Analytics with user consent mechanisms in place. Security posture is solid with HTTPS enforced and basic security best practices observed, though some HTTP security headers could be improved. The absence of WHOIS data limits domain trust verification, but the overall site professionalism and content quality support legitimacy. No critical vulnerabilities or compliance gaps were detected in the accessible content.

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

5 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. 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"

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 market position as the sole transmission system operator in the Czech Republic, serving energy producers, distributors, and market participants. Its business model is focused on regulated grid operation, maintenance, and market facilitation. The website targets energy sector professionals, partners, and the general public, providing extensive information on operations, regulatory compliance, and public communication. The presence of a subsidiary (ČEPS Invest, a.s.) indicates corporate structure complexity. The company leverages partnerships and European cooperation frameworks to enhance grid integration and market transparency. Growth indicators include active communication of innovations, regulatory updates, and career opportunities. The website's comprehensive content and structured navigation support stakeholder engagement and transparency.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, cookie consent management, and no visible exposure of sensitive data. Use of deferred and asynchronous loading of scripts reduces attack surface. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement. No vulnerability disclosure policy or security.txt file was found, which could enhance incident response readiness and transparency. The site does not expose any known vulnerabilities or suspicious scripts. Compliance with GDPR is evident through privacy and cookie policies. Overall, the security posture is adequate for a public-facing corporate website but could benefit from enhanced HTTP header configurations and formalized vulnerability disclosure mechanisms.

Recommendations

  1. Implement and enforce Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options HTTP headers to strengthen security.
  2. Publish a security.txt file or dedicated vulnerability disclosure policy to facilitate responsible reporting of security issues.
  3. Enhance accessibility features to improve compliance with WCAG standards and broaden user inclusivity.
  4. Consider adding explicit contact emails and phone numbers for customer and security incident reporting to improve transparency.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.

Technical notes

Notes

The website employs a modern technology stack including Bootstrap for responsive design, AnyChart for data visualization, Video.js for media playback, and Google Tag Manager for analytics management. Hosting assets on Microsoft Azure Blob Storage indicates scalable infrastructure. Performance is moderate with deferred script loading and preconnect hints to optimize resource fetching. SEO is supported by proper meta tags and structured navigation. Mobile optimization is good, ensuring usability across devices. Accessibility is basic but could be improved. No CMS was explicitly detected, suggesting a custom or proprietary solution. Overall, the technical implementation supports a professional and functional user experience with opportunities for further optimization and security hardening.
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.
