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

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

Avacon Natur operates in the energy sector with a focus on renewable and sustainable energy solutions. Their business model revolves around providing integrated energy services tailored to various customer segments including private customers, companies, and municipalities. The company emphasizes cost-saving decentralized energy solutions and environmental protection. Their portfolio includes heat and cold solutions, renewable energy generation, and smart quarter concepts. The company maintains a strong compliance and sustainability focus, supported by a dedicated compliance page. Social media engagement across major platforms supports brand visibility. The company appears to be medium-sized with a regional focus in Germany, leveraging partnerships and innovative projects such as hydrogen production and geothermal heating. No direct parent or subsidiary companies were identified from the website content.

Security posture

The website demonstrates a good security posture with HTTPS enabled and no exposed sensitive data. The use of Cloudflare DNS and nameservers adds a layer of protection. Cookie consent is managed via Usercentrics, indicating GDPR awareness. However, the absence of explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options suggests room for improvement. No incident response or abuse contact emails were found, which is a gap in security readiness. No vulnerability disclosure or security.txt files are present. Overall, the site is secure for general users but could enhance its security maturity by implementing additional headers and publishing incident response information.

Recommendations

  1. Implement standard security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve transparency.
  3. Add explicit incident response contact information such as security@ or abuse@ email addresses to improve readiness and trust.
  4. Enhance data retention transparency by detailing retention periods and data handling practices in the privacy policy.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced and maintain up-to-date versions.

Technical notes

Notes

The website is built on Adobe Experience Manager CMS, utilizing EON UI components for a modern and responsive design. It integrates Google Tag Manager for analytics and Usercentrics for cookie consent management, reflecting a mature digital marketing and compliance setup. Hosting and DNS are managed via Cloudflare, providing performance and security benefits. The site is mobile-optimized with good accessibility features and SEO meta tags including Open Graph and Twitter cards. Performance is moderate, with asynchronous loading of scripts and lazy loading of images. There is no indication of legacy or vulnerable libraries. The technical infrastructure supports a professional and scalable web presence suitable for a medium-sized energy company.
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.
