Stadt Arnsberg · Government · Germany
Medium risk. 3 critical or high findings in GDPR outside view and Security headers.
The website www.arnsberg.de serves as the official digital presence of the city of Arnsberg, Germany. It provides extensive information and services related to tourism, economic development, community engagement, sustainability, culture, politics, and municipal administration. The site targets residents, local businesses, tourists, and community stakeholders, positioning itself as a comprehensive municipal government portal. The business model is that of a government entity providing public services and information. Technically, the website is built on the TYPO3 CMS platform, leveraging modern web technologies such as jQuery, Bootstrap, Video.js, Leaflet, and accessibility tools like ReadSpeaker. The site demonstrates good mobile optimization, accessibility, and SEO practices, although performance is moderate. The technical infrastructure appears stable and consistent with a government website. From a security perspective, the site uses HTTPS but lacks visible security headers and explicit security or privacy policies. No vulnerability disclosure or incident response information is present. The absence of cookie and privacy policies indicates potential compliance gaps with GDPR and related regulations. No critical vulnerabilities or exposed sensitive data were detected, but security posture could be improved by implementing standard security headers and formal policies. Overall, the website is trustworthy and professional, serving its purpose as a municipal information portal. Strategic recommendations include enhancing privacy and cookie disclosures, implementing security headers, and establishing a vulnerability disclosure policy to improve compliance and security maturity.
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.
