0–100, higher is better. How it is calculated

SatNOGS is an open source project operated by the Libre Space Foundation, focused on creating a global network of satellite ground stations. The website serves as a hub for community engagement, satellite data sharing, and technical documentation. It targets satellite enthusiasts, researchers, and the open source community, positioning itself as a niche but reputable player in the space technology domain. The business model is community-driven with support through donations and open collaboration. Technically, the website is built on WordPress using standard plugins such as Jetpack and Mailchimp integration, hosted via Gandi SAS. The site demonstrates good mobile optimization, SEO practices, and moderate performance. Security is adequate with HTTPS enforced and domain transfer protections, though DNSSEC is not enabled and security headers are missing, indicating room for improvement. From a security perspective, the site shows no signs of blocking or WAF interference, and no critical vulnerabilities are evident from the content. Privacy compliance is partially addressed with a cookie consent mechanism, but no explicit privacy policy or terms of service were found. Contact information is limited to social media and a subscription form, with no direct emails or phone numbers published. Overall, SatNOGS presents a trustworthy and professional online presence for its community-driven satellite network project. Strategic improvements in security headers, privacy documentation, and vulnerability disclosure would enhance its security posture and compliance standing.

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

4 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, Twitter, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

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.

Business context

Business profile

SatNOGS operates in the specialized technology sector of satellite ground station networking. Its competitive advantage lies in its open source, participatory approach, enabling global collaboration and crowdsourced data collection. The project is supported by the Libre Space Foundation, which lends credibility and organizational structure. Revenue streams appear to be primarily donation-based, with community engagement through forums and social media. The target customers are technically savvy individuals and organizations interested in satellite data and open source space technology. Growth indicators include active community links and ongoing documentation updates. Partnerships with Libre Space Foundation and related domains strengthen its ecosystem. The business model emphasizes transparency, collaboration, and open access.

Security posture

The website maintains a moderate security maturity level with HTTPS enforced and domain transfer protections in place. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options reduces its defense-in-depth. No incident response or security policy documents are published, which may limit transparency and preparedness. The cookie consent mechanism aligns with GDPR requirements, but the lack of a privacy policy is a compliance gap. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, the security posture is adequate for a community-driven project but would benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to mitigate common web attacks.
  3. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  4. Establish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance incident response transparency by publishing security policies and contact channels.

Technical notes

Notes

The website is built on a mature and widely used CMS platform (WordPress) with a modern theme and standard plugins. The tech stack includes jQuery, Mailchimp integration, and Jetpack for analytics and sharing. Hosting is provided by Gandi SAS, a reputable registrar and hosting provider. Performance is moderate with good mobile responsiveness and SEO optimization. Accessibility is basic but present. The site uses Google Fonts and standard web technologies. Technical risks include missing DNSSEC and security headers, which could be addressed to reduce attack surface. Overall, the infrastructure is stable and suitable for the project's scope.
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.
