0–100, higher is better. How it is calculated

Energiequelle SAS is a French company specializing in the development, construction, and management of renewable energy projects, including wind, solar photovoltaic, repowering, and energy storage. Founded in 2002 and a subsidiary of the German Energiequelle GmbH since 2010, the company operates internationally with a strong presence in France. Their website reflects a professional and comprehensive presentation of their services, projects, and corporate information, targeting investors, partners, and stakeholders in the renewable energy sector. Technically, the website is built on the Neos CMS platform using modern web technologies such as PHP, JavaScript, and various libraries for UI components. The site is mobile-optimized, accessible, and SEO-friendly, with a cookie consent mechanism compliant with GDPR. However, some security headers are not explicitly detected, and no dedicated security or incident response policies are published. From a security perspective, the site uses HTTPS with good SSL configuration and implements cookie consent controls. No vulnerabilities or exposed sensitive data were found in the HTML content. The absence of WHOIS data reduces transparency but does not indicate malicious intent. Overall, the security posture is solid but could be improved by publishing explicit security policies and adding security headers. The overall risk assessment is low, with recommendations to enhance security headers, publish incident response information, and consider a security.txt file for vulnerability disclosures. The website is trustworthy, professionally maintained, and compliant with privacy regulations, making it a reliable source for business and technical information about Energiequelle SAS.

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

4 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Energiequelle SAS holds a strong market position as a medium-sized player in the renewable energy sector, focusing on wind and solar project development and operational management. Their business model revolves around project lifecycle services, from development to construction and exploitation. The company benefits from being part of the larger Energiequelle GmbH group, enhancing its international reach and credibility. Their partnerships with professional associations and active communication through news and social media indicate a well-integrated ecosystem. Growth indicators include ongoing projects, recent leadership changes, and active participation in educational and community events. The company targets institutional clients, local authorities, and investors interested in sustainable energy solutions.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and a GDPR-compliant cookie consent mechanism. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for improvement. The lack of published security policies or incident response contacts limits transparency and preparedness communication. No security.txt or vulnerability disclosure program is evident. Overall, the security maturity is good but could be enhanced by adopting best practices in security headers and public security documentation.

Recommendations

  1. Implement standard security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a dedicated security policy and incident response information on the website to improve transparency and readiness.
  3. Consider creating and hosting a security.txt file to facilitate vulnerability disclosures and improve security communication.
  4. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  5. Enhance monitoring and validation of form inputs to prevent injection attacks and ensure secure data handling.

Notes

The website is built on the Neos CMS platform leveraging the Flow PHP framework, with front-end technologies including jQuery, Owl Carousel, Lightbox2, Blueimp Gallery, and Foundation for responsive design. The site loads media-rich content including videos and images optimized for various screen sizes. Performance is moderate with room for optimization, especially in media delivery and script loading. Accessibility features such as skip links and ARIA roles are present, contributing to a good user experience. SEO is well addressed with meta tags, Open Graph, and JSON-LD structured data. The technical stack is modern and well-maintained, supporting the company's digital presence effectively.
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.
