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

Mapstodon.Space is a niche Mastodon instance dedicated to the cartography and geospatial community, providing a federated social networking platform based on Mastodon version 4.4.1. The platform targets enthusiasts and professionals interested in mapping and geospatial topics, fostering community engagement through user-generated content. The website is hosted in France and operated by an identified administrator, reflecting a small but active user base. Technically, the site leverages modern web technologies including React and Rails, with a moderate performance profile and good mobile optimization. Security posture is adequate with HTTPS enforced and domain transfer protections, though DNSSEC is not enabled and security headers are absent. Privacy compliance is basic, with a privacy policy present but lacking cookie consent mechanisms and terms of service. Overall, the site demonstrates a consistent brand and trustworthy domain registration, but could improve in security and compliance transparency.

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. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 384-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

The platform operates as a community-driven social network within the federated Mastodon ecosystem, focusing on a specialized audience interested in cartography and geospatial data. Its business model centers on providing free social networking services without advertising or monetization evident on the site. The market position is niche, serving a dedicated user segment with 405 active users reported. The platform benefits from open source technology and transparent administration, which supports trust and community growth. Partnerships or subsidiaries are not evident, and the hosting provider is alwaysdata.com. Growth indicators include active content posting and engagement, but the site lacks explicit business contact information or commercial services.

Security posture

The security maturity level is moderate. The site uses HTTPS with a valid SSL certificate and enforces clientTransferProhibited status on the domain to prevent unauthorized transfers. However, DNSSEC is not enabled, which could expose DNS to spoofing risks. No security headers such as Content-Security-Policy or X-Frame-Options were detected, which are recommended to mitigate common web vulnerabilities. There is no published security policy, incident response plan, or vulnerability disclosure program, limiting transparency and preparedness. No exposed sensitive data or vulnerable libraries were identified in the analysis. The absence of cookie consent and terms of service may pose compliance risks under GDPR. Overall, the platform should enhance its security controls and policy disclosures to improve trust and resilience.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement and publish comprehensive security and incident response policies on the website.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Introduce cookie consent mechanisms and update privacy policy to reflect GDPR compliance.
  5. Publish terms of service and vulnerability disclosure information to enhance transparency and user trust.

Technical notes

Notes

The website is built on the Mastodon platform version 4.4.1, utilizing Ruby on Rails backend and React frontend technologies. It uses modern JavaScript modules and CSS for styling, with assets served from a CDN (cdn.masto.host). Hosting is provided by alwaysdata.com, a French hosting provider. The site is mobile optimized and supports accessibility features at a basic level. Performance is moderate, with multiple module preloads and asynchronous script loading. SEO is basic with meta tags and Open Graph data present but no advanced structured data like JSON-LD for business or organization. The domain is relatively new (created in 2022) but consistent with the platform's community focus. No CMS other than Mastodon is detected. Overall, the technical infrastructure is modern and appropriate for the platform's purpose but could benefit from enhanced SEO and accessibility improvements.
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.
