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

St.Galler Stadtwerke is a regional utility provider based in St.Gallen, Switzerland, offering a comprehensive range of services including electricity, water, gas, district heating, fiber optic connectivity, and e-mobility solutions. The company positions itself as a reliable partner for the city's energy and infrastructure needs, targeting both residential and business customers. Their website reflects a professional and customer-focused approach with clear service offerings and accessible contact information. Technically, the website employs a modern technology stack including jQuery, Bootstrap, FontAwesome Pro, and the ArcGIS JavaScript API for interactive mapping. It integrates multiple analytics and marketing tools such as Google Tag Manager, Facebook Pixel, and Siteimprove Analytics. The site is mobile-optimized, accessible, and SEO-friendly, indicating a mature digital infrastructure. From a security perspective, the site uses HTTPS and includes CSRF protection scripts, but lacks visible security headers and explicit security or incident response policies.

Overall, the website is trustworthy, well-maintained, and professionally presented, with minor recommendations to enhance privacy compliance and security 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

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 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 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

  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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

St.Galler Stadtwerke operates as an essential regional utility provider in the energy and telecommunications sectors within Switzerland. Their integrated business model covers multiple utilities and infrastructure services, providing a competitive advantage in the local market. The company targets a broad customer base including residential users and commercial clients. Their digital presence supports customer engagement through portals and online services. Partnerships with local government and integration with city services (e.g., Baustellen information) indicate strong community ties. The company demonstrates growth potential through e-mobility and fiber optic offerings, aligning with modern infrastructure trends.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforcement and CSRF protection. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security policies or incident response contacts indicate areas for improvement. The use of multiple third-party analytics and tracking services without a visible cookie consent mechanism may expose the company to GDPR compliance risks. No direct vulnerabilities or sensitive data exposures were found, suggesting a generally secure environment. Enhancing transparency around security practices and implementing comprehensive headers would strengthen the security posture.

Recommendations

  1. Implement and display a comprehensive cookie consent banner to comply with GDPR and inform users about tracking.
  2. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to improve protection against common web attacks.
  3. Publish a security policy and incident response contact information to enhance transparency and preparedness.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance.
  5. Consider adding a security.txt file or vulnerability disclosure page to encourage responsible reporting of security issues.

Technical notes

Notes

The website uses a robust and modern technology stack with popular JavaScript libraries and frameworks, including jQuery, Bootstrap, and FontAwesome Pro. The integration of ArcGIS API enables advanced mapping features for product availability. The site is built on a CMS likely Adobe Experience Manager, supporting modular content and responsive design. Performance is moderate with asynchronous loading of analytics and tracking scripts. Accessibility and SEO are well addressed with proper meta tags, language attributes, and ARIA roles. Opportunities exist to optimize loading times further and enhance security headers for better technical resilience.
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.
