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

Sonneberger Jazzfreunde e.V. is a non-profit cultural organization dedicated to promoting jazz music and small arts in the Thüringisch-Fränkischer region of Germany. The website serves as the official portal for the International Sonneberger Jazztage, a well-established jazz festival entering its 39th year. The organization relies on ticket sales, sponsorships, and partnerships with local businesses and cultural institutions to operate. The website provides detailed event information, partner acknowledgments, and ticket purchasing links, targeting jazz enthusiasts and regional visitors. Technically, the website is built on the Contao CMS platform and employs modern web technologies such as jQuery, Tiny Slider, and Usercentrics for consent management. The site is mobile-optimized and presents a professional design with clear navigation. Hosting is provided by a German hosting provider, consistent with the regional focus of the organization. Performance is moderate with room for improvement in accessibility and SEO. From a security perspective, the site uses HTTPS and implements GDPR-compliant consent management. However, no explicit security headers or incident response policies are published, and no vulnerability disclosures or security certifications are evident. The absence of a terms of service page and limited security documentation suggests areas for enhancement. No critical vulnerabilities or suspicious activities were detected. Overall, the website is trustworthy, professionally maintained, and compliant with privacy regulations. Strategic improvements in security headers, incident response transparency, and SEO could further strengthen its posture 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

9 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: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

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

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319

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 organization holds a strong regional position as a cultural event organizer with a long history and a dedicated audience. Its business model is non-profit, focusing on cultural promotion rather than commercial gain. Revenue streams include ticket sales via partner platforms, sponsorships from local businesses, and community support. The partnership ecosystem is robust, involving banks, utilities, healthcare providers, and media outlets, enhancing credibility and resource access. Growth indicators include consistent event scheduling and digital presence improvements. The website reflects a stable operation with clear communication and community engagement.

Security posture

The current security maturity level is moderate. HTTPS is enforced, and GDPR compliance is addressed through Usercentrics consent management. However, the lack of visible security headers and absence of published security policies or incident response contacts indicate gaps in security best practices. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The organization would benefit from formalizing security policies, publishing incident response procedures, and implementing additional HTTP security headers to mitigate risks and enhance trust.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add a terms of service page to clarify user agreements and legal protections.
  4. Regularly audit and update third-party libraries to prevent vulnerabilities.
  5. Enhance SEO and accessibility features to improve user experience and reach.

Technical notes

Notes

The website uses a modern CMS (Contao) with common JavaScript libraries like jQuery and Tiny Slider for UI components. Usercentrics is integrated for GDPR-compliant cookie consent management. Hosting is via a German provider with nameservers indicating a stable infrastructure. Performance is moderate with responsive design for mobile devices. SEO is basic with meta tags present but could be improved. Accessibility is basic, with some ARIA attributes and skip links but no advanced features. No broken elements or errors were detected in the HTML content. Opportunities exist to enhance technical robustness by adding security headers and improving SEO and accessibility compliance.
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.
