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

7 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

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 operates as a subsidiary of the E.ON Group, leveraging its European market presence to offer energy supply and infrastructure services focused on renewable and sustainable solutions. Its business model targets both residential and commercial customers, emphasizing energy transition and digital innovation. The website supports lead generation through contact forms and educational content, indicating a customer-centric approach. Partnerships include related domains such as the EV charging webshop. The company shows strong branding consistency and market positioning as a leader in energy solutions in Croatia.

Security posture

The website demonstrates a solid security foundation with HTTPS, consent management, and no exposed sensitive data. However, it lacks publicly visible security policies or incident response information, which could be improved to enhance transparency and readiness. The use of multiple third-party scripts necessitates ongoing monitoring for vulnerabilities. No critical security issues were detected in the analysis.

Recommendations

  1. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  2. Implement and verify security headers such as X-Frame-Options and X-Content-Type-Options to enhance protection against common web attacks.
  3. Conduct regular audits of third-party scripts and libraries to identify and mitigate potential vulnerabilities.
  4. Enhance website accessibility compliance to improve user experience for all visitors.
  5. Consider adding direct contact information such as verified company phone numbers and emails on the website to improve customer trust and communication.

Technical notes

Notes

The website is built on Adobe Experience Manager, indicating a robust enterprise CMS platform. It uses modern web components and integrates with Usercentrics for GDPR-compliant consent management. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site loads multiple analytics and marketing scripts including Google Tag Manager, Hotjar, Facebook Pixel, and LinkedIn Insight. Performance is moderate with good mobile optimization. The site structure and meta tags support SEO well. Technical risks are low but depend on maintaining third-party script security and improving security header implementation.
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.
