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

Stadtwerke Rheinfelden (Baden) is a regional municipal utility company providing essential water and heat supply services to the Rheinfelden community in Germany. The website clearly communicates their role as a reliable local service provider focused on citizen welfare. Their business model is that of a municipal utility, serving residential and commercial customers with sustainable and efficient energy and water solutions. The site features clear navigation, relevant content, and partner affiliations that reinforce their local market position. Technically, the website is built on the cEasy CMS platform and incorporates modern JavaScript libraries such as jQuery and Slick Carousel for UI elements. It uses Matomo for privacy-conscious analytics and includes accessibility features and mobile optimization. Hosting is managed via domaincontrol.com DNS, typical for small to medium enterprises. Performance is moderate with good SEO and metadata implementation. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms aligned with GDPR. However, it lacks a publicly available security policy and incident response contacts, which are recommended for enhanced transparency and trust. No critical vulnerabilities or exposed sensitive data were detected. The WHOIS data is minimal but consistent with the business identity, supporting legitimacy. Overall, the website presents a professional and trustworthy digital presence for a small municipal utility. Strategic improvements include publishing a dedicated security policy, incident response information, and enhancing security headers to strengthen the security posture further.

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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  2. GDPR outside view

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

    • 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

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

Stadtwerke Rheinfelden operates as a municipal utility focused on energy and water supply within Rheinfelden, Germany. Their competitive advantage lies in their local government backing and focus on sustainable, reliable service. Revenue streams likely derive from utility fees for heat and water supply. The target customer segment is local residents and businesses requiring essential utilities. The company maintains partnerships with regional energy and infrastructure providers, as evidenced by partner logos. Growth indicators include infrastructure projects like new water tanks and heat networks. The business ecosystem is tightly integrated with local government and regional partners, emphasizing community service and sustainability.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforcement and GDPR-compliant cookie consent. The use of Matomo analytics reflects a privacy-conscious approach. However, the absence of a published security policy and incident response contacts indicates gaps in transparency and readiness. No vulnerable libraries or exposed sensitive data were found, and no WAF or blocking mechanisms interfere with access. Security headers are not explicitly detected, suggesting room for improvement. Overall, the security posture is adequate for a small municipal utility website but would benefit from enhanced documentation and technical controls.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, such as a security@ or abuse@ email address.
  3. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance transparency by detailing data retention policies and cookie usage in the privacy policy.

Technical notes

Notes

The website is built on the cEasy CMS platform version 5.3.5, using JavaScript libraries including jQuery and Slick Carousel for interactive UI components. It integrates Matomo for analytics and Google Translate for multilingual support. The site is hosted with domaincontrol.com DNS servers, indicating use of GoDaddy services. Performance is moderate with good mobile optimization and accessibility features such as skip links and ARIA labels. SEO is supported by meta tags, canonical links, and structured JSON-LD breadcrumb data. The site uses HTTPS with a valid SSL certificate. There is no evidence of technical debt or deprecated technologies, but security headers could be improved. Overall, the technical infrastructure is stable and appropriate for a small municipal utility website.
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.
