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

3 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 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  3. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Green Cell operates primarily in the energy and transportation sectors, targeting both consumers and businesses with a broad product portfolio including laptop batteries, power banks, EV chargers, and photovoltaic equipment. The business model combines direct e-commerce sales with B2B partnerships, supported by a dedicated B2B domain. The company leverages social media and digital marketing tools to maintain customer engagement and brand visibility. Its competitive advantage lies in product innovation and a comprehensive product range. The presence of legal notices, declarations of conformity, and privacy policies indicates a mature operational framework. Growth indicators include active marketing, multilingual support, and a structured product catalog.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and domain registration secured against unauthorized changes. Cookie consent is implemented with granular user controls, reflecting GDPR compliance. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party marketing and analytics scripts is balanced with privacy considerations, though continuous monitoring of these dependencies is recommended. Overall, the security posture is good but could benefit from enhanced security headers and published policies.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to strengthen browser security.
  2. Enable DNSSEC for the domain to protect against DNS spoofing and improve domain security.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  4. Establish a vulnerability disclosure program or publish a security.txt file to facilitate responsible reporting of security issues.
  5. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerable dependencies.

Technical notes

Notes

The website is built on the PrestaShop CMS platform, utilizing jQuery and various JavaScript plugins for enhanced user experience. It integrates Google Tag Manager, Facebook Pixel, and Salesmanago for analytics and marketing automation. Hosting and domain registration are managed by OVH SAS with DNS services via Cloudflare. The site is mobile-optimized with responsive design and includes accessibility features at a basic level. Performance is moderate, with opportunities to optimize loading times and enhance accessibility compliance. SEO is well addressed through meta tags and structured navigation. Overall, the technical infrastructure supports the business needs effectively but could benefit from modern security enhancements and performance tuning.
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.
