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

gruene.social is a Mastodon social networking instance operated by Netzbegruenung - Verein fuer gruene Netzkultur e.V., a German non-profit organization aligned with the Green Party. The platform serves a niche audience interested in green politics and federated social media, providing a community-focused environment without commercial advertising or intrusive tracking. The website uses Mastodon version 4.4.2 with a modern React-based frontend, indicating a contemporary technical infrastructure with good mobile optimization and moderate performance. Security posture is adequate with HTTPS usage and no exposed sensitive data, but lacks advanced security headers and explicit incident response policies.

Overall, the site is trustworthy and professionally maintained, suitable for its target audience and business model.

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.

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 organization behind gruene.social is a small non-profit focused on promoting green political culture through federated social media. Its market position is niche but stable, serving politically engaged users interested in Mastodon and the fediverse. The business model is community-driven without commercial monetization, relying on transparency and trust. The platform benefits from a consistent brand and active domain registration. External links indicate engagement with broader Mastodon and open-source communities. Growth potential lies in expanding user base within political and environmental activism circles. Partnerships appear limited to federated social media nodes and open-source projects.

Security posture

Security maturity is moderate. The site uses HTTPS and avoids exposing sensitive data. However, it lacks DNSSEC, security headers like CSP or HSTS, and does not publish incident response or vulnerability disclosure policies. No security contact emails or DPO information is provided. The absence of cookie consent and terms of service may pose compliance risks under GDPR. No known vulnerabilities or malware detected. The site would benefit from enhanced security controls and formalized policies to improve resilience and compliance.

Recommendations

  1. Enable DNSSEC to improve domain security and prevent DNS spoofing.
  2. Implement standard security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options.
  3. Publish clear terms of service and enhance privacy policy to include GDPR compliance details.
  4. Add a cookie consent mechanism to comply with privacy regulations.
  5. Establish and publish incident response and vulnerability disclosure policies including security contact information.

Technical notes

Notes

The website is built on Mastodon 4.4.2, leveraging React and modern JavaScript modules, indicating a well-maintained and up-to-date technical stack. Hosting appears to be managed via Key-Systems, LLC registrar with custom name servers, suggesting self-hosting or VPS deployment. Performance is moderate with good mobile responsiveness. SEO and accessibility are basic but functional. No CMS detected, consistent with Mastodon's architecture. Opportunities exist to improve technical SEO, accessibility, and security headers to enhance overall site robustness and user experience.
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.
