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

ohai.social operates as an independent Mastodon server providing a social networking platform within the fediverse. It offers a cozy, fast, and secure environment for users to engage in microblogging and social interaction. The platform is built on the open-source Mastodon software, leveraging modern web technologies such as React and WebSockets to deliver a responsive and user-friendly experience. The site is hosted under a German registrar with a domain created in 2022, indicating a relatively new but legitimate service. Privacy policy is present but basic, and no cookie consent mechanism is implemented, which could be improved for GDPR compliance. Security posture is good with HTTPS enforced and domain transfer protections in place, though DNSSEC is not enabled. Overall, the site demonstrates a solid technical foundation and trustworthy business presence, though it lacks some formal compliance and security documentation.

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 256-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 business model centers on providing a Mastodon instance to the fediverse community, targeting users interested in decentralized social networking. The platform maintains a modest but active user base (~1.6K active users) and is administered by the ohai.social team. The service is positioned as a welcoming and secure alternative to mainstream social networks, emphasizing privacy and community. Revenue streams or monetization are not evident from the content. The platform integrates with other Mastodon and fediverse nodes, linking to various external domains related to social media and news. No direct partnerships or subsidiaries are identified. The business operates in the technology sector with a focus on social media and open-source software.

Security posture

The site enforces HTTPS and uses domain status clientTransferProhibited to prevent unauthorized domain transfers. However, DNSSEC is not enabled, which is a recommended security enhancement. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are published. The site does not expose sensitive data in the HTML and uses modern web frameworks that are regularly updated. No known vulnerabilities or malware indicators are present. Security headers are partially implemented but could be improved with CSP and other headers. Overall, the security posture is moderate to good but could benefit from formalized policies and enhanced DNS security.

Recommendations

  1. Enable DNSSEC to improve domain name system security.
  2. Implement a cookie consent banner to comply with GDPR and privacy regulations.
  3. Publish terms of service and detailed privacy policies including GDPR compliance statements.
  4. Add a security.txt file and incident response contact information to facilitate vulnerability reporting.
  5. Enhance HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.

Technical notes

Notes

The website uses Mastodon version 4.5.0-nightly with React and modern JavaScript modules, indicating a current and actively maintained codebase. The site is mobile optimized and uses WebSockets for real-time streaming. Performance is moderate with no major issues detected. The hosting provider is not explicitly stated but the domain registrar is INWX GmbH in Germany. The site lacks a CMS but relies on Mastodon's backend. SEO is basic with meta tags and Open Graph data present. Accessibility features are basic but present. No analytics or tracking scripts were detected, indicating a privacy-conscious approach. Technical debt appears low, but improvements in security headers and compliance documentation are recommended.
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.
