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 residential customers, businesses, institutions, and municipalities with renewable energy solutions, leveraging subsidies and financing to enhance market penetration. Its competitive advantage lies in its scale, experience with nearly 70,000 installations, and comprehensive service offerings including subsidy processing and financing. The multilingual sister sites indicate a regional expansion strategy across Central and Eastern Europe. The business model is B2C and B2B focused, with a strong emphasis on customer acquisition through digital channels and lead generation forms. The company benefits from trust signals such as industry partnerships and guarantees, positioning it as a reliable and professional energy solutions provider.

Security posture

The website demonstrates a good security baseline with HTTPS, DNSSEC, and cookie consent compliance. However, it lacks publicly available security policies and incident response contacts, which are important for transparency and trust. The use of third-party marketing and analytics scripts is managed with user consent, reducing privacy risks. No obvious vulnerabilities or sensitive data exposures were detected in the HTML content. Security headers are not explicitly visible and could be improved. Overall, the security posture is solid but could benefit from enhanced transparency and additional technical controls.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and verify security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

The website is built on WordPress CMS with a modern tech stack including jQuery, Google Tag Manager, Google Analytics, and Salesmanago for marketing automation. It uses a responsive design optimized for mobile devices and includes multilingual support linking to sister sites. Hosting appears to be managed via RegZone with DNSSEC enabled, enhancing DNS security. Performance is moderate with some optimization via Autoptimize plugin for CSS and JS. Accessibility is basic but functional. SEO is well addressed with proper meta tags, Open Graph data, and JSON-LD structured data. The site uses a cookie consent banner compliant with GDPR. Overall, the technical infrastructure supports a professional and scalable online presence with room for further security and accessibility enhancements.
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.
