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

6 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • 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

The Green Web Foundation operates in the intersection of energy, technology, and non-profit sectors, focusing on digital sustainability. Their business model revolves around providing open datasets, verification services, open-source tools, and educational workshops. Revenue streams likely include donations, grants, and commercial services such as workshops. Their target customers include hosting providers, developers, and organizations seeking to reduce digital carbon emissions. The foundation has established partnerships with major organizations like Mozilla and Ford Foundation, enhancing credibility and reach. Growth indicators include active fellowship programs and community coalitions. The organization maintains a transparent and professional online presence, supporting its mission effectively.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and secure form handling via WordPress mechanisms. No security headers were detected in the provided data, which is a potential area for improvement. There is no public incident response or security policy page, nor a vulnerability disclosure mechanism such as security.txt. No exposed sensitive data or vulnerable libraries were found. Privacy compliance is strong with a detailed privacy policy and GDPR adherence. Incident response readiness and security culture indicators are not explicitly visible but the organization's transparency and professionalism suggest a responsible approach to security.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Create and maintain a security.txt file to facilitate responsible vulnerability disclosure.
  4. Add a cookie consent mechanism to comply with privacy regulations and improve user trust.
  5. Regularly audit third-party scripts and plugins to ensure no vulnerabilities or privacy risks are introduced.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using up-to-date plugins and themes, including Neve and Neve Pro. It leverages jQuery and custom JavaScript for UI interactions and lazy loading for images to optimize performance. Hosting is provided by Cloudflare and 34SP.com, ensuring reliable delivery and security. The site is mobile-optimized with responsive design and accessibility considerations. SEO is well addressed with proper meta tags, Open Graph, and JSON-LD structured data. Performance is fast with minimal blocking scripts. Technical risks are low, but adding security headers and improving privacy mechanisms would further strengthen the infrastructure.
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.
