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

Todon.eu operates as a small, volunteer-run Mastodon instance focused on radical leftist and anti-authoritarian communities, providing decentralized social media services. The platform supports multiple languages and offers enhanced Mastodon features such as increased character limits and custom themes. The website is well-branded and consistent with its community-driven mission, emphasizing privacy and anti-discrimination policies. Technically, the site runs Mastodon version 4.4.8 with a modern tech stack including Ruby on Rails and React. The site is moderately performant and mobile-optimized, though accessibility and SEO could be improved. Security posture is solid with HTTPS enforced and privacy-conscious defaults, but lacks formal security policies and some security headers. Overall, the site is trustworthy and safe, with no adult or explicit content. Contact information is limited but present via email. There are no signs of malicious activity or suspicious domains. Strategic improvements include adding a cookie consent mechanism, formalizing security policies, and enhancing accessibility. This positions Todon.eu as a niche but credible player in the decentralized social media space, serving a specific activist audience with a strong privacy and community focus.

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

6 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

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

Todon.eu targets a niche market of radical leftist and anti-authoritarian users, including activists and marginalized groups. Its competitive advantage lies in its ideological clarity, community moderation, and enhanced Mastodon features. The non-profit, volunteer-run model limits commercial pressures, focusing on user privacy and community values. The platform supports multiple languages, broadening its reach within its target audience. Partnerships are primarily within the Fediverse ecosystem, with no commercial affiliations detected. Growth indicators include active user counts (~496 monthly active users) and ongoing feature enhancements. The absence of advertising and tracking aligns with its privacy-centric ethos.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, disabled unauthenticated public timeline access, and disabled search engine indexing by default. Data retention is minimized, and moderation is active. However, the absence of a published security policy, vulnerability disclosure program, and security headers like Content-Security-Policy or X-Frame-Options represent gaps. Incident response contacts are not explicitly provided. Compliance with GDPR is implied via privacy policy but lacks explicit DPO contact. Overall, the security culture appears community-driven but could benefit from formalization and transparency enhancements.

Recommendations

  1. Publish a formal security policy and incident response plan accessible on the website.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Add a cookie consent banner and detailed cookie policy if cookies are used.
  4. Enhance website accessibility to meet WCAG standards for broader inclusivity.
  5. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.

Technical notes

Notes

The website is built on Mastodon 4.4.8, leveraging Ruby on Rails and React frameworks, with modern JavaScript module usage and SVG graphics. The site is mobile-optimized and supports multiple languages. Performance is moderate, with room for optimization in loading speed and SEO. The customizations include additional Mastodon themes and UI improvements. Hosting provider details are not explicit, but the site uses HTTPS with strong SSL configuration. No CMS detected, indicating a custom deployment of Mastodon. Technical debt appears low, but accessibility and SEO enhancements are recommended to improve user experience and discoverability.
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.
