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

Sunzil is a well-established company specializing in photovoltaic solar energy solutions, with a 40-year presence in French overseas territories. The company develops, constructs, and operates solar power plants for both residential and professional clients, offering turnkey solutions and consulting services. The website reflects a mature digital presence with comprehensive content, customer testimonials, and recognized certifications such as ISO 9001 and ISO 14001, reinforcing its market credibility. Technically, the website is built on WordPress with WooCommerce and Gravity Forms, leveraging modern JavaScript libraries and analytics tools including Google Analytics and Facebook Pixel. The site is mobile-optimized and includes GDPR-compliant cookie consent mechanisms, indicating a good level of digital maturity and privacy awareness. From a security perspective, the site enforces HTTPS and employs cookie consent banners, but lacks explicit security policies and incident response information. Some JavaScript errors related to WooCommerce payment gateway dependencies were noted, which could affect user experience. The absence of WHOIS domain registration data raises concerns about domain legitimacy, although the website content and certifications suggest a legitimate business. Overall, Sunzil presents a professional and trustworthy online presence with room for improvement in security transparency and domain registration clarity.

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

8 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Sunzil operates in the renewable energy sector, focusing on photovoltaic solutions tailored for overseas French territories. Its competitive advantage lies in its long-standing regional presence and comprehensive service offerings from project guidance to operation. The business model includes direct sales, turnkey project delivery, and maintenance services. Partnerships with major energy companies and certifications enhance its market position. The website targets both individual consumers and professional clients, indicating a broad customer base. Growth indicators include active content updates and multiple regional solutions. Strategic observations suggest the company could benefit from enhanced security disclosures and clearer domain registration to strengthen trust.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and cookie consent mechanisms in place, aligning with GDPR requirements. However, the lack of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates gaps in security transparency. JavaScript errors related to payment gateway dependencies may pose functional risks. No exposed sensitive data or obvious vulnerabilities were detected in the HTML content. The missing WHOIS data for the domain is a notable concern for domain legitimacy and trust. Overall, while basic security practices are observed, improvements in policy publication and technical error resolution are recommended to enhance security maturity.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Implement and explicitly configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Resolve JavaScript dependency errors related to WooCommerce payment gateways to ensure full functionality and reduce potential attack vectors.
  4. Add a security.txt file to facilitate vulnerability disclosure and improve security communication.
  5. Clarify domain registration details or ensure WHOIS data is publicly available to enhance domain legitimacy and trustworthiness.

Technical notes

Notes

The website is built on a WordPress CMS platform using the AKN theme, integrated with WooCommerce for e-commerce capabilities and Gravity Forms for data collection. It employs modern front-end libraries such as jQuery and Slick Carousel, and uses Google Analytics and Facebook Pixel for tracking and marketing. The site is mobile-optimized with responsive design and includes SEO best practices like meta tags and structured data (JSON-LD). Performance is moderate with some deferred scripts and lazy loading. Technical debt is minimal but JavaScript errors related to payment gateway dependencies indicate areas for improvement. Hosting provider details are not explicitly identified. Overall, the technical infrastructure supports a professional and functional user experience.
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.
