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

ELEKTROTRANS a.s. is a well-established Czech company specializing in electricity transmission and distribution services, including design, construction, diagnostics, and maintenance of high voltage lines. As a member of the VINCI Energies Group under the Omexom brand, it leverages international expertise and resources, positioning itself as a market leader in the Czech Republic's energy sector. The website reflects a professional digital presence with good content quality, clear navigation, and GDPR-compliant privacy and cookie policies. Technically, the site uses WordPress with modern plugins like Yoast SEO and Matomo analytics, indicating a moderate to good digital maturity. Security posture is strong with HTTPS enforced and privacy-friendly analytics, though additional security headers and explicit incident response information could enhance trust. The absence of WHOIS data limits domain trust assessment, but overall, the site appears legitimate and professionally managed.

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

4 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: Facebook, LinkedIn, Google APIs

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

  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.

    • 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

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 targets energy sector clients requiring comprehensive electricity transmission and distribution solutions. Its business model is B2B, focusing on engineering, construction, and maintenance services. Affiliation with VINCI Energies Group provides competitive advantages through shared knowledge and resources. The website's content and social media presence support brand credibility and market positioning. Growth indicators include recent news updates and active engagement in industry events. The partnership ecosystem is centered around VINCI Energies and related energy companies in the Czech Republic.

Security posture

ELEKTROTRANS demonstrates a mature security posture with HTTPS enforced and GDPR-compliant cookie consent mechanisms. Use of Matomo analytics reflects privacy-conscious data collection. However, the site lacks visible security headers such as Content-Security-Policy and does not publish incident response or vulnerability disclosure information. No contact channels for security incidents are provided. These gaps suggest room for improvement in transparency and proactive security communication. No vulnerabilities or exposed sensitive data were detected in the analyzed content.

Recommendations

  1. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a security policy and incident response contact information on the website to improve transparency and readiness.
  3. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Regularly audit third-party scripts and plugins to ensure no vulnerable libraries are in use.

Technical notes

Notes

The website is built on WordPress CMS using modern plugins such as Yoast SEO for search optimization and Matomo for analytics, indicating a focus on privacy and SEO. The site uses jQuery and W3 Total Cache for performance optimization. The presence of lazy loading for images improves load times. The site is mobile responsive with good navigation clarity. Performance is moderate, with potential improvements in caching and script optimization. No major technical debt or outdated technologies were detected, but adding modern security headers and accessibility enhancements would strengthen the technical posture.
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.
