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

Changelog.social operates as an independent Mastodon server focused on delivering news and podcasts tailored for developers. It positions itself within the fediverse as a niche community platform, leveraging the Mastodon open-source social networking software. The site provides a curated experience for technology enthusiasts and developers, emphasizing content relevance and community engagement. The business model centers on community participation without evident monetization or advertising, reflecting a small-scale, focused service launched in 2022. Technically, the website employs Mastodon version 4.4.1 with a React-based frontend, utilizing modern JavaScript modules and a CDN for asset delivery. The domain is registered through Tucows with privacy protection, and DNS is managed via DNSimple. Performance and mobile optimization are moderate to good, though SEO and accessibility features are basic. The site lacks a CMS and appears self-hosted or hosted by an unknown provider. From a security perspective, the site enforces HTTPS and has domain transfer protections enabled. However, it lacks DNSSEC, security headers, and explicit security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected, but improvements in security headers and compliance documentation are recommended. Privacy compliance is partial, with a basic privacy policy present but no cookie consent or terms of service. Overall, changelog.social presents a trustworthy, niche community platform with good technical foundations but room for improvement in privacy compliance and security best practices. Strategic enhancements in security policies, consent mechanisms, and transparency would strengthen its risk posture and user trust.

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

5 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  2. 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

  3. 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

Changelog.social targets developers and technology enthusiasts by providing a Mastodon-based social network focused on developer news and podcasts. Its competitive advantage lies in its niche focus within the fediverse and leveraging open-source Mastodon technology. The business model is community-driven without evident monetization, relying on user participation. Growth indicators include a small but active user base and recent domain registration. The partnership ecosystem includes Mastodon and open-source communities, with no commercial partners identified. Operationally, the platform emphasizes transparency through open-source code references but lacks formal business contact details or certifications.

Security posture

The security maturity of changelog.social is moderate. HTTPS is enforced, and domain registration includes transfer prohibitions enhancing domain security. However, the absence of DNSSEC, security headers, and formal security policies indicates gaps in defense-in-depth. No incident response or vulnerability disclosure mechanisms are published, limiting transparency and preparedness. Privacy compliance is partial, with a privacy policy but no cookie consent or terms of service. No exposed vulnerabilities or sensitive data were found, but the site would benefit from adopting security best practices such as CSP headers, HSTS, and publishing security contact information to improve resilience and compliance.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a cookie consent mechanism and update privacy policy to reflect GDPR compliance.
  4. Publish a clear terms of service and security policy including incident response contacts.
  5. Consider establishing a vulnerability disclosure policy and hosting a security.txt file for transparency.

Technical notes

Notes

The website is built on Mastodon 4.4.1 with a React frontend using modern JavaScript ES modules. It uses DNSimple for DNS management and Tucows as the domain registrar with privacy protection. The site assets are served via a CDN (cdn.changelog.social). Performance is moderate with good mobile optimization but basic SEO and accessibility features. No CMS is detected, indicating a custom or platform-specific deployment. The technical stack is modern and appropriate for a social networking platform but could benefit from enhanced security configurations 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.
