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

2 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. 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

Moodle operates primarily in the education sector, offering an open source LMS that is widely adopted by institutions globally. Its business model combines free software distribution with commercial services via partner sites such as Moodle.com and Moodle Academy. The company benefits from a large, active user community and a broad ecosystem of plugins and translations. Market positioning is strong as a leader in open source e-learning solutions, with a focus on scalability and pedagogical soundness. The website supports this with clear navigation to community forums, documentation, and development resources. Partnerships with Moodle.com and Moodle Academy enhance its commercial reach and educational offerings. Growth indicators include extensive language support and a large number of registered sites worldwide.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, clientDeleteProhibited domain status, and cookie consent mechanisms in place. Security headers are likely implemented though not explicitly listed in the HTML. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a published security policy, incident response contacts, and a security.txt file represents a gap in transparency and vulnerability management. DNSSEC is not enabled, which could be improved to enhance DNS security. Overall, the site is secure for users but could benefit from enhanced disclosure of security practices and incident response readiness.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Publish a dedicated security policy page including incident response procedures and contact channels.
  3. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance transparency by providing direct contact information for security and privacy inquiries.

Technical notes

Notes

The website is built on a robust and mature technology stack featuring YUI libraries, RequireJS, jQuery, and Bootstrap, indicating a blend of legacy and modern JavaScript frameworks. Hosting is supported by Cloudflare DNS and GoDaddy registrar, with HTTPS enforced for secure communications. Performance is moderate with combined and minified CSS/JS assets, though some legacy YUI usage may indicate technical debt. The site is mobile optimized and accessible, with good SEO practices including meta tags and Open Graph data. Cookie consent is managed via OneTrust, reflecting compliance with privacy regulations. Opportunities exist to modernize the tech stack further and enable DNSSEC for improved security.
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.
