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

The website www.filderstadt.de serves as the official municipal portal for the city of Filderstadt, Germany. It provides comprehensive information and services for residents, tourists, and businesses, including citizen offices, appointment booking, economic development, education, and tourism. The site is well-structured with extensive navigation and a consistent branding approach, reflecting a professional municipal government presence. The target audience primarily includes local citizens, visitors, and commercial entities within the region. Technically, the website employs a modern technology stack featuring jQuery, jQuery UI, FontAwesome, and other JavaScript libraries, built on the dvv-Mastertemplates CMS platform. It is hosted on German-based servers with secure HTTPS configuration. The site demonstrates good mobile optimization, accessibility, and SEO practices, although performance is moderate. From a security perspective, the site uses HTTPS and deferred script loading, but lacks explicit security headers such as Content-Security-Policy and X-Frame-Options in the provided data. No vulnerabilities or exposed sensitive data were detected. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in security transparency and readiness. Overall, the website is safe, trustworthy, and suitable for general audiences, with no adult or questionable content. The WHOIS data aligns with a legitimate municipal entity, reinforcing the site's credibility. Strategic recommendations include publishing a clear privacy policy, enhancing security headers, and providing incident response information to strengthen 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.

Priority findings

5 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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Filderstadt's municipal website positions itself as a central hub for local government services, targeting residents, businesses, and tourists. The business model is that of a public sector entity delivering administrative, social, economic, and cultural services. The site highlights key services such as citizen offices, economic development programs, educational resources, and tourism promotion. The presence of social media channels and newsletters indicates active community engagement. The site does not reveal revenue streams but focuses on public service delivery. Growth indicators include comprehensive service offerings and digital presence. Partnerships or subsidiaries are not evident from the data. The website supports the city's role as a government authority with a medium-sized operational scale.

Security posture

The website demonstrates a baseline security posture with HTTPS enabled and no visible security flaws in the HTML content. The use of deferred JavaScript loading and absence of exposed credentials are positive indicators. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces defense-in-depth. No published security policy or incident response contacts limit transparency and preparedness. There is no evidence of vulnerability disclosure or security.txt files. Compliance with GDPR is implied but not explicitly documented via a privacy policy. Overall, the security maturity is moderate, suitable for a government informational site but with opportunities for enhancement.

Recommendations

  1. Publish a comprehensive and accessible privacy policy to improve GDPR compliance and user trust.
  2. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide a public security policy and incident response contact information to enhance transparency and readiness.
  4. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Regularly update and audit third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on the dvv-Mastertemplates CMS platform version 10.5.0-RELEASE, utilizing modern JavaScript libraries such as jQuery 3.6.4, jQuery UI 1.13.2, FontAwesome 5, Owl Carousel, Slidebars, and Lightbox. The site uses deferred script loading to optimize performance. Hosting appears to be with German providers as indicated by nameservers (kivbf.de, frei.net). The site is mobile optimized and includes accessibility features such as skip links and ARIA labels. SEO is supported by proper meta tags including Open Graph metadata. Performance is moderate, likely due to the extensive navigation and content volume. There is no evidence of server-side frameworks or platforms beyond the CMS. Overall, the technical infrastructure is stable but could benefit from performance tuning and enhanced security configurations.
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.
