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

9 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

      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. Security headers

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 households and businesses interested in sustainable energy solutions, leveraging government subsidies to enhance affordability. Their business model combines product sales, installation services, and subsidy facilitation, positioning them as a full-service provider in the photovoltaic market. The partnership with Benekov Esco and the unique controller technology provide competitive advantages. The domain age aligns with the company's recent founding, supporting legitimacy. Marketing efforts include Google Analytics and Ads, with moderate user tracking balanced by GDPR compliance. The company maintains a focused local presence without evident expansion or subsidiaries.

Security posture

The website employs HTTPS and includes cookie consent mechanisms, reflecting baseline security and privacy compliance. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not detected, representing an area for improvement. The contact form includes GDPR consent, reducing privacy risks. No vulnerabilities or exposed sensitive data were identified in the HTML content. Incident response and security policies are not publicly documented, which could be enhanced to improve transparency and readiness. Overall, the security posture is moderate but could benefit from additional hardening and policy disclosures.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response plan to increase transparency and preparedness.
  3. Regularly audit and update WordPress core, themes, and plugins to mitigate vulnerabilities.
  4. Enhance accessibility features to improve usability for all users.
  5. Consider adding a terms of service page to clarify user and business obligations.

Technical notes

Notes

The website is built on WordPress CMS using the Elementor page builder, integrating modern JavaScript libraries such as Swiper and Owl Carousel for UI components. Google Tag Manager is used for analytics and marketing tags, including Google Analytics and Google Ads conversion tracking. The site is hosted with a Czech registrar (REG-WEDOS) and uses HTTPS, indicating a secure transport layer. Performance is moderate with caching and minified CSS/JS assets. Mobile optimization is good, with responsive design and accessible navigation. The site lacks some advanced SEO and accessibility features but maintains a solid technical foundation suitable for a small energy services business.
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.
