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

Yiff.Life is a small, independent Mastodon instance focused on serving the furry and LGBTQA+ communities. It operates as a non-commercial, donation-supported platform with a clear community orientation. The instance is administered by an individual known as 'Sky @ WHY2025' and features contributions from known artists. Technically, the platform runs on a dedicated Hetzner cloud VM, uses a Glitch-Soc fork of Mastodon, and leverages modern web technologies including React and ES modules. The infrastructure includes daily backups and CDN hosting, indicating a reasonable level of operational maturity. Security posture is adequate with HTTPS enabled and domain transfer protections, but lacks DNSSEC and published security policies. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism. Overall, the website is accessible, well-structured, and serves a niche adult audience with moderate trustworthiness.

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 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

  3. 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

The platform occupies a niche market within decentralized social media, targeting furry and LGBTQA+ users. Its business model is non-commercial, relying on donations via Patreon and Ko-fi, which aligns with its community-driven ethos. The use of open source software and public code repositories enhances transparency and trust. The absence of advertising and tracking tools suggests a privacy-conscious approach. The instance's small size and focused audience position it as a specialized community hub rather than a mass-market social network. Partnerships with Patreon, Ko-fi, and Mastodon ecosystem sites support its operational and community engagement strategies.

Security posture

Security maturity is moderate. The site enforces HTTPS and uses clientTransferProhibited status on the domain, which protects against unauthorized transfers. Daily backups and CDN usage indicate good operational security practices. However, the lack of DNSSEC reduces DNS security, and no security headers were detected in the HTML content. There is no public incident response or vulnerability disclosure policy, which limits transparency in handling security events. No security contact emails were found. These gaps suggest room for improvement in formalizing security governance and enhancing technical defenses.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  2. Implement and publish a formal security policy and incident response contact information.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Introduce a cookie consent mechanism to improve privacy compliance and user transparency.
  5. Consider expanding privacy compliance documentation to address GDPR and other regulations explicitly.

Technical notes

Notes

The website is built on a modern tech stack centered around a Glitch-Soc fork of Mastodon, utilizing React and ES modules for frontend delivery. Hosting on a dedicated Hetzner VM with CDN support from DigitalOcean Spaces and backups to Backblaze B2 demonstrates a robust infrastructure. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by proper meta tags and Open Graph data. The absence of a CMS is consistent with the use of Mastodon software. Overall, the technical implementation is solid but could benefit from enhanced security headers and formalized privacy controls.
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.
