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

Landeshauptstadt Erfurt operates the official city portal for the capital of Thuringia, Germany, providing comprehensive information and services related to city administration, culture, education, economy, and citizen services. The website serves a broad audience including residents, visitors, and businesses, positioning itself as a central digital hub for municipal engagement and information dissemination. The business model is public sector focused, delivering government transparency and community resources. Technically, the site is built on the IMPERIA CMS platform with a mix of legacy and modern JavaScript libraries such as jQuery and Flexslider, enhanced with accessibility and SEO best practices. The site is mobile optimized and employs privacy-conscious analytics (Matomo) with Do Not Track and cookie consent mechanisms in place, reflecting a mature digital infrastructure. Security posture is solid with HTTPS enforced and privacy-respecting analytics, though there is room for improvement by adding security headers and explicit incident response information. No vulnerabilities or suspicious content were detected. The domain WHOIS data is limited but consistent with institutional hosting, supporting legitimacy. Overall, the website is professional, trustworthy, and well-maintained, fulfilling its role as an official government portal effectively.

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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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

Erfurt.de is positioned as the authoritative digital presence for the city government of Erfurt, offering extensive services and information to citizens and stakeholders. Its competitive advantage lies in comprehensive content coverage, official endorsement, and integration with local economic and cultural initiatives. Revenue streams are typical for government entities, focusing on public service rather than profit. The partnership ecosystem includes local tourism and recruitment portals, enhancing community engagement. Growth indicators include active event promotion and digital service expansion. Strategic observations highlight the importance of maintaining up-to-date content and enhancing security transparency to sustain public trust.

Security posture

The website demonstrates a mature security posture with HTTPS encryption, privacy-focused analytics configuration, and no exposed sensitive data. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options suggests potential areas for hardening. No incident response or vulnerability disclosure mechanisms are publicly available, which could be improved to align with best practices and regulatory expectations. The use of older jQuery versions may pose risks if not regularly patched. Overall, the site is secure for its purpose but would benefit from enhanced security policies and transparency.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  2. Publish a security policy page and provide clear incident response contact information to improve transparency and trust.
  3. Upgrade JavaScript libraries such as jQuery to the latest stable versions to mitigate known vulnerabilities.
  4. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  5. Maintain and regularly audit privacy and cookie consent mechanisms to ensure ongoing GDPR compliance.

Technical notes

Notes

The website is powered by the IMPERIA CMS, a specialized content management system for public sector use, combined with a variety of JavaScript libraries including jQuery (versions 1.7.1 and 3.5.1), jQuery UI, Flexslider for slideshows, Shariff for social sharing, and LazySizes for image lazy loading. The CSS framework YAML is used for layout and responsive design. The site loads asynchronously analytics scripts from a self-hosted Matomo instance, configured with privacy in mind. Performance is moderate with good mobile optimization and accessibility features such as skip links and screen reader labels. Technical debt is minimal but updating legacy libraries would improve security and maintainability.
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.
