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

Mamot.fr is a French-language Mastodon server operated by the non-profit organization La Quadrature du Net. It serves as a federated social media platform within the fediverse, targeting privacy-conscious and francophone users. The website provides social networking services without commercial advertising, emphasizing community and open-source values. The platform is technically mature, running Mastodon version 4.3.4 with modern web technologies including React and WebSockets, hosted by Scaleway. The site demonstrates good performance and mobile optimization, though accessibility could be improved. Security posture is strong with HTTPS enforced, security headers implied, and domain registration consistent and transparent. However, the site lacks explicit cookie consent mechanisms, terms of service, and published security policies, which are areas for improvement. Overall, Mamot.fr is a trustworthy and well-maintained platform with a clear non-profit mission and a solid technical foundation.

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.

    • 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. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

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

La Quadrature du Net operates Mamot.fr as an independent Mastodon instance focusing on the francophone community and privacy advocacy. The business model is non-profit, providing free social networking services without advertising or tracking. The server has an active user base of approximately 2,800 monthly active users, indicating a modest but engaged community. The organization benefits from a strong reputation in digital rights and privacy, which supports trust and user retention. The platform's open-source nature and federation with the wider fediverse ecosystem enhance its competitive positioning. Partnerships include uptime monitoring via uptime.lqdn.fr and alignment with Mastodon's official resources. Growth potential lies in expanding user engagement and improving compliance and transparency features.

Security posture

The website exhibits a mature security posture with enforced HTTPS, use of integrity attributes on scripts and stylesheets, and domain status flags that prevent unauthorized transfers. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. The lack of cookie consent may also pose GDPR compliance risks. Overall, the platform is secure but would benefit from formalizing security governance documentation and user-facing transparency. Incident response readiness and communication channels should be established to enhance trust and regulatory compliance.

Recommendations

  1. Implement a clear cookie consent banner and mechanism to comply with GDPR requirements.
  2. Publish terms of service and security policy pages to improve transparency and legal compliance.
  3. Establish and publicize incident response contacts such as security@ or abuse@ email addresses.
  4. Enhance website accessibility features to improve usability for all users.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on Mastodon 4.3.4, leveraging React and modern JavaScript frameworks. It uses SVG for logos and icons, and CSS with integrity checks for stylesheets. Hosting is provided by Scaleway, a reputable cloud provider. The site is mobile optimized and uses WebSockets for real-time streaming. Performance is moderate with room for improvement in SEO and accessibility. No CMS is detected, indicating a custom or platform-specific implementation. The technical stack is modern and well-maintained, with no visible technical debt or deprecated technologies. Opportunities exist to improve metadata completeness and accessibility compliance.
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.
