EnVys, a.s. operates a community energy platform in the Czech Republic, offering long-term stable electricity prices sourced directly from local power plants.

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

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube, 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

EnVys positions itself as a community energy provider focusing on direct electricity supply from local power plants, bypassing foreign market volatility. Their business model includes reserving shares in local energy production with contracts spanning 25 years. The company serves multiple customer segments including households, businesses, and municipalities, offering tailored solutions and emphasizing environmental sustainability. The website content and downloadable documents indicate a transparent approach with pre-contractual information and terms of service readily available. The integration of analytics and marketing tools suggests active customer engagement and growth orientation. No direct partnerships or subsidiaries were identified from the domain analysis.

Security posture

The website employs HTTPS with no visible security header configurations in the provided data, indicating room for improvement in security hardening. Cookie consent and privacy policies are implemented, reflecting GDPR awareness. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a dedicated security policy or incident response contact limits transparency in security governance. The use of third-party scripts like Google Analytics and Microsoft Clarity introduces typical tracking risks but is managed with user consent. Overall, the security posture is adequate for a commercial website but could benefit from enhanced header policies and incident response disclosures.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Regularly audit and update third-party scripts to minimize vulnerabilities and privacy risks.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Consider publishing domain registration details or using verified WHOIS data to increase trustworthiness.

Technical notes

Notes

The website uses a modern technology stack including Blazor WebAssembly for frontend interactivity, jQuery for legacy support, and Swiper.js for UI components. Analytics are handled via Google Analytics and Microsoft Clarity, with marketing and retargeting scripts from Google Tag Manager and Seznam. The site loads asynchronously external scripts to optimize performance. Mobile optimization is good with responsive design and clear navigation. However, no CMS was detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the data. Performance is moderate, with potential improvements in accessibility and SEO through enhanced semantic markup and ARIA attributes.
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.
