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

Wissenschaft trötet is a Mastodon-based social networking platform hosted on wisskomm.social, primarily serving the scientific community associated with the Informationsdienst Wissenschaft (idw). The platform facilitates content sharing and social interaction among members of scientific institutions. It positions itself as an independent Mastodon server within the fediverse, focusing on community-driven content without advertising or algorithmic interference. The website demonstrates a consistent and professional branding aligned with its scientific audience. Technically, the site leverages Mastodon version 4.4.7 with React and modern JavaScript modules, providing a responsive and moderately performant user experience. Security posture is adequate with HTTPS implied and no visible vulnerabilities, though security headers and explicit policies are lacking. Privacy compliance is basic, with a privacy policy present but no cookie consent or terms of service pages. Overall, the site is safe, trustworthy, and suitable for general audiences, but could improve in transparency 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

4 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

  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 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

The platform targets the scientific community, offering a niche social networking service that integrates with the broader fediverse. Its business model is community-focused rather than commercial, with no evident monetization or advertising. The presence of an admin account and active user statistics indicate a managed and active community. The lack of detailed business or contact information suggests a small-scale operation, likely non-commercial or institutionally supported. The platform benefits from the open-source Mastodon ecosystem, enabling scalability and federation. Strategic partnerships or subsidiaries are not evident. Growth potential lies in expanding scientific user engagement and enhancing platform features.

Security posture

The security maturity level is moderate. The site uses HTTPS and WebSocket Secure (wss) for streaming, indicating encrypted communications. However, the absence of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No incident response or security policy information is published, which could hinder timely handling of security events. No vulnerabilities or exposed sensitive data were detected in the analysis. Privacy compliance is minimal, lacking cookie consent mechanisms and GDPR explicit indicators. The platform would benefit from formalizing security policies, improving header configurations, and publishing incident response contacts to enhance trust and compliance.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to strengthen security posture.
  2. Add a cookie consent banner and detailed cookie policy to improve privacy compliance and user transparency.
  3. Publish a clear terms of service and security policy page to inform users and establish legal protections.
  4. Establish and publicize incident response contacts and procedures to improve security readiness.
  5. Enhance accessibility features and SEO optimization to improve user experience and discoverability.

Technical notes

Notes

The website is built on Mastodon 4.4.7, utilizing React and modern JavaScript ES modules, indicating a contemporary technology stack. The use of WebSocket Secure (wss) for streaming APIs supports real-time interactions. The site includes multiple favicon sizes and Apple touch icons, showing attention to cross-device compatibility. Performance is moderate with no major issues detected, though no explicit performance metrics were available. SEO is basic with standard meta tags and Open Graph data but lacks structured data like JSON-LD. Accessibility is basic, with some ARIA labels and semantic HTML but could be improved. Hosting provider details are not disclosed. Overall, the technical infrastructure is solid for a community social platform but could benefit from enhanced SEO and accessibility 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.
