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

Stadttheater Gießen is a prominent publicly funded cultural institution in Hessen, Germany, operating as a five-division theater with a broad regional influence. The website serves as a comprehensive portal for visitors, offering detailed information about performances, ticketing, educational programs, and services for people with disabilities. The organization targets theatergoers, schools, and the local community, positioning itself as a key cultural hub with a strong public service orientation. Technically, the website employs a modern technology stack including jQuery, Bootstrap, and various UI libraries such as Fancybox and Slick Slider, likely built on the Kirby CMS platform. Hosting is managed via Schlundtech, a reputable provider. The site is mobile-optimized with good SEO practices and moderate performance, delivering a professional and accessible user experience. From a security perspective, the site enforces HTTPS and implements a GDPR-compliant cookie consent mechanism. However, it lacks explicit security headers and does not provide a public security policy or incident response contacts. No vulnerabilities or exposed sensitive data were detected. Overall, the security posture is solid but could be enhanced with additional headers and transparency. The website demonstrates high business credibility with clear contact details, social media presence, and trust signals such as privacy policies and terms of service. The domain registration aligns with the business profile, showing no suspicious patterns. The overall risk is low, with recommendations focusing on improving security headers and incident response transparency to further strengthen trust and compliance.

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

6 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. 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"

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

Stadttheater Gießen operates as a medium-sized, publicly funded theater institution serving the Hessen region. Its business model revolves around cultural event production, ticket sales, subscriptions, and educational outreach. The theater maintains a strong market position as one of six major publicly financed theaters in the state, leveraging partnerships such as its dedicated webshop for ticketing. The organization targets a diverse audience including local residents, cultural enthusiasts, and educational institutions. Growth indicators include active event programming and community engagement through newsletters and social media. The partnership ecosystem includes ticketing platforms and cultural networks. Strategic observations suggest a stable operation with opportunities to enhance digital security and user engagement through improved technical measures.

Security posture

The website exhibits a mature security posture with mandatory HTTPS encryption and a robust cookie consent framework ensuring GDPR compliance. The absence of security headers such as Content-Security-Policy and X-Frame-Options represents a gap that could expose the site to certain web-based attacks. No incident response or security contact information is publicly available, which limits transparency and readiness perception. The use of up-to-date libraries and no visible vulnerabilities indicate good maintenance practices. Compliance with data protection regulations is evident, but further enhancements in security policy publication and header implementation would elevate the security maturity and resilience against emerging threats.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to mitigate common web vulnerabilities.
  2. Publish a clear security policy and provide dedicated incident response contact channels to improve transparency and readiness.
  3. Regularly audit and update third-party libraries to ensure no vulnerable versions are in use.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  5. Consider performance optimizations to improve loading speed and reduce resource usage, especially on mobile devices.

Technical notes

Notes

The website is built on a modern and modular technology stack featuring jQuery, Bootstrap, Fancybox, Slick Slider, and Masonry for layout and interactivity, likely managed via the Kirby CMS. Hosting is provided by Schlundtech, a professional German hosting provider. The site includes responsive design elements and SEO-friendly metadata including Open Graph tags. Performance is moderate with asynchronous loading of analytics scripts. The use of Swig templating indicates server-side rendering of dynamic content. Technical risks are minimal but could be reduced by implementing security headers and optimizing resource loading. The infrastructure supports a professional and scalable digital presence aligned with the organization's cultural mission.
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.
