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 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
    • 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

Bolhinha positions itself as a niche Mastodon server focusing on Portuguese speakers, differentiating from larger Mastodon instances by community language and moderation style. Its business model is community-driven, likely relying on donations as indicated by the donation link. The server has a small but active user base (~70 active users). The lack of extensive business information and contact details suggests a lean operation focused on social networking services rather than commercial activities. The use of open-source Mastodon software and GitHub presence aligns with community trust and transparency.

Security posture

The website enforces HTTPS and uses domain status protections to prevent unauthorized domain changes. However, DNSSEC is not enabled, and no advanced security headers were detected. There are no published security policies or incident response contacts, which limits transparency and preparedness. The absence of cookie consent and terms of service pages indicates partial compliance with privacy regulations. Overall, the security posture is moderate but could be improved by enabling DNSSEC, adding security headers, and publishing security and privacy policies.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and publish a comprehensive privacy policy including GDPR compliance details.
  3. Add a cookie consent mechanism to comply with privacy regulations.
  4. Publish terms of service and security incident response policies to enhance transparency and trust.
  5. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.

Technical notes

Notes

The site uses Mastodon version 4.5.0-alpha.1 with a React-based frontend and modern JavaScript modules. It relies on external CDN domains for assets and scripts. The hosting provider is not explicitly stated but domain registration is via Porkbun with DNS servers at desec.io. Performance is moderate with good mobile optimization and basic accessibility. SEO is basic with standard meta tags and Open Graph data. The technical stack is modern and appropriate for a federated social network instance, but there is room for improvement in security configurations and privacy 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.
