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

Jazzclub Ilmenau e.V. is a small non-profit cultural organization based in Ilmenau, Germany, dedicated to promoting jazz music through event organization and community engagement. The website serves as an information hub for upcoming jazz events, membership opportunities, and sponsorship acknowledgments. The organization targets jazz musicians and enthusiasts within the local community, positioning itself as a key cultural institution in the region. Technically, the website is built using the Jekyll static site generator, hosted by manitu.net, and employs modern web standards with responsive design and good SEO practices. However, the site lacks advanced security headers and cookie consent mechanisms, which are important for GDPR compliance and overall security posture. The security posture is moderate with HTTPS enabled but missing several best practices such as security policies and incident response contacts. Overall, the website is trustworthy and professional but could benefit from enhanced privacy and security features to improve compliance 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

8 findings rated critical or high. Fix these first.

  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

    • 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: Telnet

      Port 23 (Telnet) is publicly accessible - Telnet - Unencrypted remote access

      What to do: Immediately restrict access to Telnet using firewall or VPN

      • NIS2 21(2)(e)

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 · found on this site
  • 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 Ilmenau e.V. operates as a cultural non-profit entity focusing on jazz music promotion in Ilmenau. Its business model relies on memberships, sponsorships, and event hosting, targeting local jazz enthusiasts and musicians. The organization maintains partnerships with regional cultural and governmental bodies, as evidenced by sponsorship logos linking to official domains. The website's content and structure support community engagement and transparency. The absence of commercial advertising or tracking tools aligns with the non-profit nature and community focus. Growth indicators include scheduled events for 2025 and active social media channels. Strategic observations suggest opportunities to enhance digital presence through improved privacy compliance and security transparency.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly implemented, ensuring encrypted communications. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No visible forms or input fields reduce attack surface, but the lack of published security policies and incident response contacts indicates limited preparedness for security incidents. GDPR compliance is partial, with a privacy policy present but no cookie consent mechanism. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security posture is adequate for a small non-profit but requires improvements to meet best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive security headers to enhance protection against web vulnerabilities.
  2. Add a cookie policy and consent mechanism to comply with GDPR and improve user privacy transparency.
  3. Publish a clear security policy and incident response contact information to demonstrate security readiness.
  4. Regularly review and update website dependencies and hosting configurations to maintain security hygiene.
  5. Enhance accessibility features and conduct periodic audits to improve user experience and compliance.

Technical notes

Notes

The website is built using the Jekyll static site generator, indicating a modern and lightweight technical infrastructure. It uses standard HTML5, CSS, and SVG for graphics, ensuring compatibility and responsiveness. Hosting is provided by manitu.net, a reputable German hosting provider. The site includes proper meta tags for SEO and social media integration via Open Graph and Twitter cards. Performance is moderate, with no heavy scripts or analytics detected, contributing to fast load times. Mobile optimization is good, with responsive navigation and layout. Accessibility is basic but could be improved with additional ARIA attributes and semantic markup. The absence of analytics and tracking scripts suggests a privacy-conscious approach but limits insights into user behavior.
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.
