Medium risk. 4 critical or high findings in GDPR outside view and SSL/TLS.
zirk.us operates as an independent Mastodon server focused on the arts and humanities community, providing a niche social networking platform within the fediverse. The website targets readers, writers, academics, and enthusiasts of literature, philosophy, film, music, culture, politics, history, and architecture. It positions itself as a community-driven platform emphasizing open conversation and cultural engagement. The domain is mature, registered since 2004, and hosted under GoDaddy.com, LLC with a registrant address in Germany, aligning with the website's language and content focus. Technically, the site runs Mastodon version 4.4.3, leveraging Ruby on Rails and React frameworks, with modern JavaScript module usage and SVG-based iconography. The site is mobile-optimized with good navigation and SEO practices, though performance is moderate. Hosting details beyond the registrar are not explicit. No CMS is detected, consistent with Mastodon's custom platform nature. Security posture is adequate with HTTPS enforced and domain registration protections in place, but lacks security headers and DNSSEC. Privacy compliance is partial; a privacy policy exists but no cookie consent or terms of service pages are found. No incident response or security contact information is published. No advertising or tracking technologies are detected, indicating minimal user tracking. Overall, the site is safe, professional, and trustworthy for its target audience, but could improve privacy compliance and security hardening. The lack of explicit contact information and terms of service may impact user trust and legal compliance. Strategic improvements in security headers, cookie consent, and incident response transparency are recommended.
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.
4 findings rated critical or high. Fix these first.
These are the privacy signals visitors and data protection authorities look for under GDPR.
GDPR requires clear information about cookie usage
What to do: Add a dedicated cookie policy explaining cookie usage and purposes
GDPR requires explicit consent for non-essential cookies
What to do: Implement a cookie consent banner that appears on first visit
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
Server supports weak protocols: TLSv1.1
What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions
SSL certificate uses 384-bit key, which is considered weak
What to do: Use at least 2048-bit RSA or 256-bit ECC key

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.
