The website skyjake.fi hosts a personal Mastodon instance operated by an individual known as 'skyjake'. The site serves as a social platform within the fediverse, focusing on personal and technical content related to software projects such as Gemini protocol applications and the Doomsday Engine. The domain has been registered since 2010, indicating a long-term personal project. The site is small-scale, targeting a niche audience interested in open-source and federated social networking. Technically, the site runs Mastodon version 4.3.8, uses modern web technologies including JavaScript and SVG, and is hosted under a Finnish registrar. The site is mobile-optimized and provides a good user experience with clear navigation and consistent branding. Security posture is solid with HTTPS enabled and no obvious vulnerabilities, though it lacks advanced security headers and published security policies.

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. 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

Skyjake.fi operates as a personal Mastodon server, providing social networking services within the fediverse. The business model is non-commercial and community-focused, serving a small user base of active users. The operator is a graphics and multimedia researcher with a strong technical background, contributing to open-source projects and Gemini protocol development. The site’s market position is niche, appealing to technology enthusiasts and federated social network users. There are no commercial partnerships or subsidiaries identified. The site links to related technical projects and Gemini capsules, indicating a specialized ecosystem. Growth indicators are limited due to the personal nature of the service. The operator maintains transparency through verified links and PGP key publication, enhancing trust within the community.

Security posture

The security maturity of skyjake.fi is moderate to good. The site enforces HTTPS and avoids exposing sensitive data in its HTML content. No vulnerable or outdated libraries were detected in the loaded scripts. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces the overall security hardening. There is no published security policy or incident response information, which limits transparency in case of security incidents. Privacy compliance is minimal, lacking cookie consent mechanisms and GDPR-specific disclosures. The site does not appear to collect extensive user data or use tracking technologies, which reduces privacy risks. Overall, the site is secure for its purpose but could improve by adopting additional security best practices and publishing relevant policies.

Recommendations

  1. Implement and enforce security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Add a cookie consent banner and detailed cookie policy to improve privacy compliance.
  3. Publish a clear security policy and incident response plan accessible to users.
  4. Consider adding contact information for security incidents such as security@ or abuse@ email addresses.
  5. Regularly audit and update software dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The site is built on Mastodon 4.3.8, a modern open-source federated social network platform using Ruby on Rails backend and JavaScript frontend. The frontend uses chunked CSS and JS with integrity hashes, indicating good security practices in resource loading. The site supports WebSockets for streaming API connections. The hosting is likely provided by Louhi Net Oy, a Finnish registrar and hosting provider. Performance is moderate with good mobile optimization and basic accessibility features. SEO is basic with proper meta tags and Open Graph data but lacks advanced SEO optimizations. The site does not use third-party analytics or advertising, reducing external dependencies and privacy concerns. Overall, the technical infrastructure is solid for a personal Mastodon instance but could benefit from enhanced accessibility and SEO improvements.
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.
