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

Gemeinde Lindau operates an official municipal website providing comprehensive information and services to its residents and interested parties. The site covers a broad range of topics including local politics, administration, public services, events, education, and community life. It serves as a primary digital touchpoint for the municipality, offering online service access such as an online counter for administrative tasks and room reservations. The website targets local citizens and stakeholders seeking municipal information and services. Technically, the website employs modern web technologies including Bootstrap for responsive design, JavaScript modules, and a Swiss-based CMS platform (i-web.ch). The site is well-structured, mobile-optimized, and includes accessibility features such as skip links and ARIA roles. Performance is moderate with efficient use of images and scripts. SEO is adequately addressed with meta tags and structured navigation. From a security perspective, the site enforces HTTPS and uses secure form submissions for login. It includes a cookie consent mechanism aligned with GDPR requirements and anonymizes web analytics data. However, explicit security headers are not detected, and no public security or incident response policies are available. No vulnerabilities or exposed sensitive data were found in the content. The WHOIS data confirms the domain's legitimacy and consistency with the municipality's identity. Overall, the website presents a low-risk profile with good privacy compliance and business credibility. Strategic improvements could include adding explicit security policies, incident response contacts, and enhanced security headers to further strengthen the security posture.

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

5 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

The website firmly positions Gemeinde Lindau as a local government entity providing essential public services and information. Its business model is service-oriented, focusing on citizen engagement and administrative efficiency through digital channels. The site supports community involvement via event announcements, political information, and online service access. The partnership ecosystem includes local educational institutions and community organizations. Growth indicators include active content updates and integration of online service features. The platform's competitive advantage lies in its official status and comprehensive service coverage for the municipality's residents.

Security posture

The current security maturity level is moderate to good. HTTPS is enforced, and secure login forms are implemented. Privacy compliance is evident through cookie consent and anonymized analytics. However, the absence of security headers and public security policies indicates room for improvement. No visible vulnerabilities or data leaks were detected. Incident response readiness is unclear due to lack of published contacts or policies. The security culture appears basic but functional, suitable for a municipal website with limited attack surface.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page including contact channels for reporting security issues.
  3. Consider adding a vulnerability disclosure or security.txt file to encourage responsible reporting of security concerns.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.
  5. Enhance user authentication security by implementing multi-factor authentication for administrative access.

Technical notes

Notes

The website uses a Swiss-based CMS (i-web.ch) with Bootstrap framework for responsive design and modular JavaScript for interactivity. The site loads multiple CSS and JS assets efficiently and uses import maps for module management. Images are served via a Swiss API endpoint, indicating localized hosting. Accessibility features such as skip links and ARIA roles are implemented. SEO is supported by meta tags and structured navigation menus. Performance is moderate, with potential optimization in script loading and caching. The technical stack is modern but could benefit from additional security hardening and performance tuning.
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.
