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

No critical or high findings. These medium findings are worth fixing next.

  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.

    • Medium

      Missing Permissions-Policy header

      Controls browser features and APIs

      What to do: Implement a Permissions-Policy to restrict feature access

      • OWASP Secure Headers: OWASP Secure Headers Project recommends Permissions-Policy: accelerometer=(), autoplay=(), camera=(), cross-origin-isolated=(),…
  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Medium

      DMARC not enforcing

      DMARC policy is set to "none"

      What to do: Gradually move to "quarantine" then "reject" policy

    • Medium

      No DKIM record found

      DKIM adds cryptographic signatures to emails

      What to do: Configure DKIM with your email provider

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

      What to do: Implement MTA-STS to prevent downgrade attacks

  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.

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 municipality positions itself as a community-focused government entity emphasizing quality of life, sustainability, and citizen engagement. Key services include digital citizen portals, event information, and integration of local energy and infrastructure data. Partnerships with certified service providers like BITE GmbH and regional IT centers indicate a strategic approach to technology adoption. The business model is service-oriented, funded by public resources, targeting residents, local businesses, and tourists. Growth indicators include digital transformation efforts and community event facilitation. The partnership ecosystem supports secure and compliant data processing. The website content and structure support transparency and accessibility, reinforcing the municipality's commitment to public service.

Security posture

The website exhibits a robust security posture with enforced HTTPS, presence of multiple security headers, and use of ISO 27001 certified service providers. Cookie consent and privacy policies are comprehensive and GDPR compliant. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a public incident response policy and vulnerability disclosure mechanism represents a gap in security transparency and readiness. The use of Cloudflare DNS and CDN services adds an additional layer of protection. Overall, the security maturity is high for a municipal website but could benefit from formalized incident response disclosures.

Recommendations

  1. Publish a clear incident response policy and provide a dedicated security contact email.
  2. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Enhance transparency on data retention and processing practices in privacy documentation.
  4. Regularly audit and minimize third-party scripts and cookies to reduce privacy risks.
  5. Consider adding a terms of service page to clarify user rights and obligations.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and secure content management system widely used in government and enterprise sectors. It uses modern frontend libraries such as Swiper.js for interactive elements and Font Awesome for icons. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site is mobile optimized and accessible, with good SEO practices including meta tags and Open Graph data. Performance is moderate, likely due to rich media content and multiple scripts, but overall user experience is smooth. Technical risks are minimal, with no outdated or vulnerable libraries detected. Opportunities exist to further modernize by adopting progressive web app features and enhancing performance optimizations.
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.
