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

1 finding rated critical or high. Fix these first.

  1. 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

Mozilla Foundation operates as a large nonprofit entity in the technology sector, focusing on internet openness and digital rights. Their business model revolves around advocacy, grantmaking, community campaigns, and research. The foundation leverages partnerships and community involvement to amplify impact. Revenue streams likely include donations and grants, supported by fundraising widgets on the site. The target audience includes internet users, technology advocates, and open source communities worldwide. The organization maintains a consistent brand and high-quality content, positioning itself as a leader in nonprofit technology advocacy.

Security posture

The website demonstrates a mature security posture with HTTPS enabled, comprehensive security headers, and no visible vulnerabilities or exposed sensitive data. Privacy compliance is supported by detailed privacy and cookie policies and a consent mechanism. However, the absence of a public security policy, incident response contacts, or vulnerability disclosure program suggests areas for improvement in transparency and incident readiness. No critical security issues were detected, and the site follows best practices for web security and privacy.

Recommendations

  1. Publish a detailed security policy and incident response plan accessible on the website.
  2. Provide explicit contact channels for security incidents such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance transparency around data retention policies and user data handling.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.

Technical notes

Notes

The website is built using the Wagtail CMS framework, leveraging modern JavaScript libraries and third-party services such as Google Tag Manager and FundraiseUp for analytics and fundraising. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with room for optimization in loading speed. The use of structured data (JSON-LD) improves SEO and content discoverability. Cookie consent and privacy compliance tools are well integrated. Hosting provider details are not explicitly identified. Overall, the technical infrastructure supports a professional and secure online presence.
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.
