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

7 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

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 foundation operates primarily in the non-profit sector with a focus on education, social support, and environmental initiatives. Its business model revolves around grant programs, educational outreach, and employee volunteerism. The organization benefits from a strong partnership ecosystem including educational platforms and web development partners. The domain age and registration details align well with the foundation's history, supporting credibility. The website content is rich and relevant, targeting educators, families, and community members. Marketing and analytics tools are used responsibly with GDPR compliance. The foundation's digital maturity is moderate to high, with opportunities to enhance security transparency and incident response readiness.

Security posture

The website exhibits a mature security posture with HTTPS enforced and integration of Google reCAPTCHA v3 to mitigate automated abuse. The use of a CMP ensures GDPR compliance and user consent management. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit security headers such as X-Frame-Options and X-Content-Type-Options were not clearly identified and should be confirmed. There is no publicly available incident response or vulnerability disclosure policy, which could be improved to enhance security culture and transparency. Overall, the site is secure but could benefit from formalizing security policies and publishing them.

Recommendations

  1. Verify and implement explicit security headers like X-Frame-Options and X-Content-Type-Options to strengthen browser security.
  2. Publish an incident response policy and vulnerability disclosure guidelines to improve transparency and readiness.
  3. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  4. Enhance data retention policy disclosures to align with GDPR best practices.
  5. Maintain and expand trust signals such as certifications or awards to reinforce credibility.

The website uses a modern tech stack including Alpine.js for interactivity, Google reCAPTCHA for bot protection, and a CMP for consent management. The presence of Google Tag Manager and Exponea indicates advanced analytics and marketing capabilities. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with potential for optimization in loading times. The CMS is not explicitly identified, suggesting a custom or proprietary solution. Hosting details are not disclosed.

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.
