It serves 46 municipal administrations across several cities and districts, supporting over 18,000 office workplaces with IT solutions and services. The organization employs over 500 staff members and is positioned among the top ten municipal IT providers in Germany. The website reflects a professional government entity with clear business focus and target audience in the public sector. Technically, the website is built on Drupal CMS, hosted likely on Deutsche Telekom infrastructure, and uses modern web technologies including SVG icons and JavaScript. It is mobile-optimized, accessible, and includes SEO best practices. Analytics are implemented via eTracker with cookie blocking enabled, though no explicit cookie consent mechanism is present. From a security perspective, the site uses HTTPS with good SSL configuration and no visible vulnerabilities or exposed sensitive data. However, security headers are not explicitly detected, and no published security or incident response policies are found. Privacy compliance is good with a comprehensive privacy policy, but cookie consent and vulnerability disclosure policies are missing. Overall, the website is trustworthy, professional, and secure with minor areas for improvement in privacy compliance and security transparency. No WAF or blocking mechanisms interfere with content access, enabling full analysis.
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.

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.

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.
