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

The website typo3.social is a Mastodon instance operated by the TYPO3 Association, serving as a community-driven social networking platform within the fediverse. It provides users with a decentralized social media experience focused on the TYPO3 community. The site leverages the open-source Mastodon platform (version 4.4.3) and modern web technologies such as React and ES modules, indicating a contemporary technical infrastructure. The site is mobile optimized and offers a good user experience with clear navigation and consistent branding. From a security perspective, the site uses HTTPS (implied by external links and modern practices), but no explicit security headers were detected in the provided data. There is no evidence of exposed sensitive data or vulnerable libraries. However, the absence of cookie consent mechanisms and detailed contact or incident response information suggests room for improvement in privacy compliance and security transparency. The WHOIS data is unavailable due to TLD restrictions, but the site content and branding align with a legitimate community server. Overall, the website presents a moderate risk profile with good business credibility and technical implementation but requires enhancements in privacy compliance and security best practices to improve trust and user protection.

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

3 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 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

TYPO3 Association operates this Mastodon server to support its community engagement and social networking needs. The business model is community and association-driven, focusing on providing a platform for users interested in TYPO3 and the fediverse. The market position is niche, targeting users who prefer decentralized social media. The site does not display commercial advertising or affiliate programs, indicating a non-commercial or low-commercial intent. The partnership ecosystem includes links to Mastodon official resources and GitHub, reflecting open-source collaboration. Growth indicators are limited due to the small active user base (8 active users in last 30 days). Strategic observations suggest focusing on expanding user engagement and improving compliance to enhance reputation.

Security posture

The security maturity level is moderate. The site uses HTTPS and modern web technologies but lacks visible security headers and explicit privacy or security policies. No vulnerabilities or exposed sensitive data were detected in the HTML content. Compliance gaps include missing cookie consent and absence of incident response contact information. Data protection practices are minimal but no direct risks are evident. Incident response readiness cannot be assessed due to lack of information. The security culture appears basic, typical for community-run servers. Recommendations include implementing security headers, cookie consent, and publishing security policies to strengthen posture.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  2. Add a cookie consent banner to comply with privacy regulations and improve user trust.
  3. Publish clear contact information and an incident response policy to enhance transparency and readiness.
  4. Improve accessibility features to meet broader user needs and compliance standards.
  5. Enhance SEO metadata and structured data to improve discoverability and professional appearance.

Technical notes

Notes

The website is built on the Mastodon platform version 4.4.3, utilizing React and modern JavaScript ES modules for frontend functionality. The use of SVG icons and responsive design indicates attention to modern web standards. Performance is moderate, with no explicit performance metrics but no signs of slow loading or errors. The site lacks a traditional CMS but is a specialized social platform. Hosting provider details are not disclosed. Technical risks are low but could increase if security headers and privacy mechanisms are not implemented. Opportunities exist to modernize privacy compliance and enhance SEO and accessibility.
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.
