Low risk. 2 critical or high findings in GDPR outside view.
The website helmholtz.social serves as a dedicated Mastodon instance for the Helmholtz Association of German Research Centers, facilitating decentralized and institutional scientific communication. It is positioned as a non-commercial platform targeting Helmholtz centers, their member institutions, and selected initiatives. The platform leverages modern open-source technologies, primarily Mastodon version 4.4.8, with a React-based frontend and WebSocket streaming for real-time feeds. Hosting is provided by a German company with servers located in the EU, ensuring compliance with regional data protection laws. From a security perspective, the site enforces HTTPS and employs encrypted connections, though explicit security headers are not evident in the HTML source. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is strong, with a comprehensive GDPR-aligned privacy policy and clear data retention practices. Contact information and legal disclosures are thorough, enhancing business credibility and trust. However, the absence of a cookie consent mechanism and terms of service page are areas for improvement. Overall, the site demonstrates a mature technical infrastructure and a solid security posture appropriate for an institutional platform. The lack of WHOIS data due to TLD restrictions is mitigated by the detailed legal imprint and contact transparency. The platform is safe for general audiences, with no adult or questionable content. Strategic recommendations include enhancing security headers, publishing incident response policies, and implementing cookie consent to further strengthen compliance and trust.
Scanned
NIS2 Art. 21(2)
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.

These are the privacy signals visitors and data protection authorities look for under GDPR.

Each check with its score, findings and the evidence it collected.
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
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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
