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

Gemeindewerke Villmergen is a Swiss municipal utility company providing essential services including electricity, water, and heat supply, along with complementary services such as electrical installations, e-mobility charging solutions, and photovoltaic system planning and installation. The company positions itself as a local energy provider focused on sustainable and future-oriented energy solutions, targeting private customers, businesses, and large clients within the Villmergen region. Their digital presence reflects a well-structured and professionally designed website with clear navigation and comprehensive service offerings. Technically, the website is built on a Swiss CMS platform (i-web.ch) utilizing modern frontend technologies such as JavaScript, CSS, and Swiper.js for interactive elements. The site is mobile-optimized, accessible, and performs moderately well. Privacy compliance is strong, with a clear privacy and cookie policy including a consent mechanism. Analytics are handled via a custom anonymized web statistics service hosted in Switzerland, ensuring user privacy. From a security perspective, the site enforces HTTPS with excellent SSL configuration but lacks explicit security headers and publicly available security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected. The WHOIS data is consistent with the business claims, indicating a legitimate and trustworthy domain registration. Overall, the website demonstrates a solid digital maturity level with good business credibility and privacy compliance. Strategic improvements could include publishing a formal security policy, adding security headers, and providing a vulnerability disclosure channel to enhance trust and 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. 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

  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. 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

  4. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

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

Gemeindewerke Villmergen operates as a local municipal utility focused on energy and water supply services. Their competitive advantage lies in offering integrated energy solutions including renewable energy (photovoltaics) and e-mobility infrastructure, aligning with sustainability trends. The business model centers on direct service provision to local residents, businesses, and large customers, supported by digital customer portals and online services. The company maintains a partnership ecosystem with local government and energy service providers. Growth indicators include active promotion of future-oriented services like solar energy and electric vehicle charging. The website content and structure reflect a stable, customer-focused operation with a clear market position in the Swiss energy sector.

Security posture

The website exhibits a mature security posture with mandatory HTTPS and no visible exposure of sensitive data. However, it lacks implementation of common security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options, which could mitigate certain web-based attacks. There is no publicly disclosed security policy or incident response contact, which limits transparency and readiness perception. No vulnerability disclosure or security.txt file is present, reducing avenues for responsible vulnerability reporting. Privacy compliance is strong, with anonymized analytics and cookie consent mechanisms. Overall, the security posture is good but could be improved by adopting additional security best practices and transparency measures.

Recommendations

  1. Implement and configure security headers including CSP, HSTS, and X-Frame-Options to enhance web security.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Continue maintaining strong privacy compliance and transparent cookie consent mechanisms.
  5. Regularly review and update technical stack and CMS components to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on the i-web.ch CMS platform, leveraging modern frontend technologies such as JavaScript and CSS with responsive design principles. Interactive components like carousels use Swiper.js. The site loads with moderate performance and is optimized for mobile devices with good accessibility features. Meta tags and SEO elements are properly configured, supporting search engine visibility. No deprecated or vulnerable libraries were detected in the provided HTML content. Hosting details are not explicitly disclosed, but the use of Swiss-based analytics and CMS suggests local hosting or CDN usage. Technical risks are minimal but could be further reduced by implementing security headers and continuous performance monitoring.
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.
