Partial score · DNS & email only

52/100

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

Stadtwerke Saarbrücken is a large municipal utility company serving the Saarbrücken region in Germany, providing energy, water, and public transport services. The website reflects a professional and regionally focused business with a strong market position as a key regional employer and service provider. The technical infrastructure uses modern JavaScript libraries and a TYPO3 CMS backend, indicating moderate digital maturity. Security posture is adequate with HTTPS enforced but lacks advanced security headers and explicit privacy and cookie policies. Tracking is done via eTracker without visible consent mechanisms, indicating room for privacy compliance improvement. Overall, the website is trustworthy and well-maintained but could enhance security and privacy transparency.

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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

  • Security headers: did not complete in this scan.
  • 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 company operates in essential public sectors including energy generation and distribution, water supply, and public transportation. It targets local residents and businesses, emphasizing regional economic impact and employment. The business model is that of a municipal utility with diversified services including swimming pools and public transport advertising. Partnerships with city government and related service providers are evident. The company shows growth and community engagement through training programs and infrastructure expansion. The website content and external links reinforce its role as a stable, community-oriented enterprise.

Security posture

The website enforces HTTPS and uses reputable JavaScript libraries, but lacks visible security headers such as Content Security Policy, HSTS, and X-Frame-Options. No incident response or vulnerability disclosure information is found, which is a gap in security transparency. No exposed sensitive data or vulnerable libraries were detected in the provided content. The absence of cookie consent mechanisms and privacy policies indicates partial GDPR compliance. Overall, the security posture is moderate but can be improved by implementing recommended headers, policies, and transparency measures.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Add security headers including CSP, HSTS, X-Frame-Options to enhance protection against common web attacks.
  3. Publish incident response and vulnerability disclosure information to improve security transparency and readiness.
  4. Conduct regular audits of third-party libraries and update them to mitigate vulnerabilities.
  5. Enhance accessibility features to meet modern standards and improve user experience for all users.

Technical notes

Notes

The website uses a modern tech stack including jQuery 3.7.1, Owl Carousel, Air Datepicker, Foundation framework, and Select2 for UI components. It is likely powered by TYPO3 CMS, inferred from backend URL patterns. The site loads moderate CSS and JS assets and includes accessibility tools like ReadSpeaker. Performance is moderate with room for optimization. Mobile responsiveness is good, and SEO basics are covered with meta tags and canonical links. However, the site lacks advanced SEO and accessibility features and could benefit from performance tuning and enhanced 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.
