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

Hansestadt Lüneburg operates an official municipal website providing comprehensive information and services to its citizens and visitors. The site covers a broad range of topics including local government, administration, climate protection, culture, and public services. It serves as a primary communication channel for the city, offering news, event information, and access to online administrative services via a dedicated service portal. The website targets residents, local businesses, and tourists, positioning itself as a trusted and authoritative source for city-related information. Technically, the website is built on the Neos CMS platform using the Flow PHP framework, enhanced with modern JavaScript libraries such as jQuery, Alpine.js, and Mapbox GL for interactive maps. Accessibility is a priority, demonstrated by the integration of Eye-Able tools. The site is mobile-optimized and employs standard SEO practices including structured data (JSON-LD) and Open Graph metadata. Hosting appears stable with dedicated name servers, and HTTPS is enforced ensuring secure communications. From a security perspective, the website demonstrates good practices including HTTPS, cookie consent mechanisms, and no visible sensitive data exposure. However, it lacks publicly available security policies, incident response contacts, and vulnerability disclosure information, which are recommended for enhanced transparency and trust. No WAF or blocking mechanisms were detected, and no vulnerabilities were apparent in the provided content. Overall, the website is professional, secure, and compliant with GDPR requirements, providing a positive user experience and reliable business credibility. Strategic recommendations include publishing a security policy, incident response details, and a vulnerability disclosure framework to further strengthen 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

6 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. 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';…

  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.

Business context

Business profile

Hansestadt Lüneburg is positioned as a key municipal government entity serving the city of Lüneburg, Germany. Its competitive advantage lies in its official status and comprehensive digital presence that facilitates citizen engagement and administrative efficiency. The business model is centered on public service delivery, information dissemination, and community engagement. Revenue streams are typical of municipal governments, primarily from public funding rather than commercial activities. The target customer segments include residents, local businesses, tourists, and governmental partners. Growth indicators include ongoing digitalization efforts such as expanding online services and climate protection initiatives. The partnership ecosystem includes regional government bodies, economic development agencies, and tourism organizations. Strategic observations highlight a focus on accessibility, transparency, and digital service expansion to meet modern citizen expectations.

Security posture

The security maturity of the Hansestadt Lüneburg website is moderate to good. The site enforces HTTPS, employs cookie consent mechanisms compliant with GDPR, and integrates accessibility tools that enhance user security and privacy. No exposed sensitive information or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and preparedness. The use of third-party scripts is controlled, but continuous monitoring is advised to mitigate supply chain risks. Overall, the site demonstrates a responsible security culture but would benefit from formalizing and publishing additional security governance documents to align with best practices and regulatory expectations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Regularly audit and update third-party libraries and scripts to minimize vulnerabilities.

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.
