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. 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  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 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

Greencarbon positions itself as a niche player in the environmental sustainability sector, focusing on CO₂ compensation projects certified in the Netherlands and Belgium. Its business model revolves around providing a platform for organizations to calculate and offset their carbon footprint, supported by partnerships with project developers and certification bodies. The company targets MKB and government sectors, offering both productized certificates and consultancy services. The presence of whitepapers, e-books, and educational content indicates a strategy to build thought leadership and customer engagement. The integration with Shopify and use of multiple marketing tools suggests a digitally mature approach to customer acquisition and retention. Social media presence on Instagram, YouTube, and LinkedIn supports brand visibility and community engagement.

Security posture

The website employs HTTPS with a valid SSL certificate, ensuring encrypted communications. It uses cookie consent mechanisms compliant with GDPR, and no sensitive data is exposed in the HTML source. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and Referrer-Policy are not evident, which could be improved to mitigate common web vulnerabilities. There is no published security policy or incident response contact, nor a vulnerability disclosure program, which are recommended best practices. The use of reputable third-party analytics and marketing services is balanced with privacy compliance. Overall, the security posture is good but could be enhanced with additional headers and formal policies.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and Referrer-Policy.
  3. Publish a formal security policy and incident response contact information on the website.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.

Technical notes

Notes

The website is built on the Shopify platform using the Dawn theme, which provides a modern, responsive design framework. It integrates multiple third-party services for analytics (HubSpot, Google Tag Manager, Hotjar), marketing (Futy Widget), and cookie consent (CookieYes). The site uses asynchronous loading for scripts to optimize performance. The hosting and CDN are managed by Shopify and Cronon GmbH as registrar. Performance is moderate with good mobile optimization and accessibility features. SEO is supported by proper meta tags, Open Graph, and JSON-LD structured data. There is room for improvement in security headers and formal documentation of security practices.
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.
