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.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

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 Jazzclub Erfurt e.V. operates as a local cultural institution with a niche focus on jazz music events in Erfurt, Germany. Its business model revolves around organizing concerts and cultural events, supported by public funding and community engagement. The club targets jazz fans and local residents interested in cultural diversity and creative music. The website reflects a stable market position within the local cultural sector, with no indication of commercial revenue streams beyond ticket sales and memberships. The partnership ecosystem includes cultural funding bodies such as Initiative Musik Berlin. Growth indicators are modest, consistent with a small non-profit entity. The organization maintains transparency through event calendars and social media engagement but lacks detailed business disclosures or certifications.

Security posture

The website demonstrates a moderate security maturity level. It employs HTTPS (assumed from standard practice though not explicitly confirmed), uses captcha technology (Altcha) to mitigate automated abuse, and implements cookie consent for privacy compliance. However, there is an absence of key security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended to enhance protection against common web attacks. No vulnerability disclosures or incident response contacts are published, indicating limited formal security governance. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The security posture is adequate for a small cultural website but could benefit from enhanced security controls and transparency to improve resilience and trust.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Publish explicit security and incident response policies including contact channels for reporting security issues.
  3. Verify and ensure HTTPS is properly configured and enforced site-wide.
  4. Regularly update and audit third-party libraries and scripts to mitigate vulnerabilities.
  5. Enhance SEO and accessibility features to improve user experience and reach.

Technical notes

Notes

The website is built on the ClubDesk CMS platform, leveraging modern JavaScript libraries such as jQuery 3.6.0, Featherlight for lightbox functionality, AOS for scroll animations, and Owl Carousel for content sliders. CookieConsent 3.1.1 is used for GDPR compliance. The site is hosted with DNS providers dns-zonen.ch, indicating Swiss-based DNS management. Performance is moderate with no critical errors detected, and the site is mobile-optimized with basic accessibility features. Technical debt appears low, but SEO and advanced accessibility could be improved. No server-side or backend technologies were explicitly identified from the HTML content. Overall, the technical infrastructure is adequate for a small cultural organization but could be modernized further for enhanced performance and security.
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.
