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

The website www.leonberg.de serves as the official municipal portal for the city of Leonberg, Germany. It provides citizens and visitors with access to city news, public services, cultural events, and administrative information. The site targets residents and local stakeholders, positioning itself as a trusted government resource. The business model is that of a public sector service provider, focusing on transparency and accessibility. Technically, the site employs a modern JavaScript stack including jQuery, Mustache.js, and accessibility tools from DIGIaccess GmbH. The presence of a comprehensive accessibility tool indicates a strong commitment to inclusivity. The site is mobile-optimized and uses HTTPS, ensuring secure communications. However, some security headers and explicit security policies are not evident in the provided data. From a security perspective, the site demonstrates good practices such as HTTPS enforcement and cookie consent mechanisms. No critical vulnerabilities or exposed sensitive data were detected. The WHOIS data aligns with the site’s designer company, Advantic GmbH, lending legitimacy. However, the absence of detailed registrant information and incident response contacts suggests room for improvement. Overall, the website is a well-maintained government portal with strong accessibility and privacy compliance. Strategic enhancements in security headers, incident response transparency, and contact information would further strengthen its security posture 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.

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

4 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

    • 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

  2. 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

Leonberg.de operates as a municipal government website providing essential services and information to its local population. Its market positioning is that of a trusted public authority portal. The site’s competitive advantage lies in its comprehensive accessibility features and clear privacy compliance. Revenue streams are typical of government-funded entities, focusing on public service rather than commercial gain. The target customer segment includes residents, businesses, and visitors to Leonberg. Growth indicators include ongoing content updates and integration of modern accessibility tools. The partnership ecosystem includes the design and hosting company Advantic GmbH and accessibility provider DIGIaccess GmbH. Strategic observations highlight a focus on digital inclusivity and compliance with GDPR regulations.

Security posture

The website exhibits a mature security posture with HTTPS enabled and cookie consent mechanisms in place. The integration of accessibility tools also suggests attention to user safety and compliance. However, the lack of visible security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS indicates potential areas for enhancement. No evidence of vulnerable libraries or exposed sensitive data was found. The absence of explicit incident response contacts or security policies reduces transparency. Compliance with GDPR is supported by a clear privacy policy and cookie banner. Overall, the site is secure but would benefit from implementing additional security headers and publishing incident response information.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Conduct regular audits of third-party scripts and libraries to ensure no vulnerabilities are introduced.
  4. Enhance contact information visibility, including official emails and phone numbers for user support and security reporting.
  5. Maintain and update accessibility features to comply with evolving standards and user needs.

Technical notes

Notes

The website uses a combination of jQuery, jQuery UI, Mustache.js, and custom ikiss framework scripts, indicating a moderately modern tech stack. Accessibility is enhanced through integration with DIGIaccess GmbH tools and ReadSpeaker services. The site is mobile-optimized with responsive CSS and dark mode support. Performance appears moderate, with asynchronous loading of some scripts. The CMS is likely a custom or ikiss-based system. Hosting details are not explicit but name servers point to Advantic GmbH, which also designed the site. Technical risks include reliance on multiple third-party scripts and lack of visible security headers. Opportunities exist to modernize further with newer frameworks and improve 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.
