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

Yverdon Énergies is a public utility entity responsible for the distribution of electricity, gas, potable water, and management of public lighting in the city of Yverdon-les-Bains, Switzerland. The website serves multiple target audiences including tenants, property owners, property management companies, and businesses, providing tailored information and services for each. The business operates as a local public service provider with a medium-sized footprint and a clear focus on sustainable energy and utility management. Technically, the website is built on WordPress with modern plugins such as Yoast SEO and CookieYes for cookie consent management. It uses Bootstrap for responsive design and integrates Google Tag Manager and reCAPTCHA for analytics and security. The site is hosted behind Cloudflare, ensuring good performance and security. The website is mobile-optimized and has good SEO practices, although accessibility features could be enhanced. From a security perspective, the site uses HTTPS and includes bot protection via Google reCAPTCHA. Cookie consent is implemented with detailed categorization, supporting GDPR compliance. However, explicit security headers and a published security policy or incident response contacts are missing, representing areas for improvement. No critical vulnerabilities or suspicious patterns were detected. Overall, Yverdon Énergies presents a trustworthy and professional online presence consistent with its role as a public utility. The site is safe for general audiences, with no adult or questionable content. Strategic recommendations include enhancing security headers, publishing privacy and security policies, and improving accessibility to further strengthen compliance and user trust.

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.

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 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  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

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

Yverdon Énergies occupies a stable position as a public utility provider in the Swiss energy sector, focusing on essential services such as electricity, gas, water distribution, and public lighting management. Its business model is that of a public entity serving local residents and businesses. The website targets distinct customer segments including tenants, property owners, property managers, and enterprises, indicating a diversified service approach. The use of multilingual content suggests an inclusive strategy to reach a broader audience. The integration of modern web technologies and cookie consent mechanisms reflects awareness of digital compliance and user experience. No direct revenue streams or partnerships were explicitly identified in the content, but the presence of a client portal indicates ongoing customer engagement and service delivery. The company appears to maintain a consistent brand and professional communication style, supporting its credibility in the market.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS encryption and integration of Google reCAPTCHA to mitigate spam and bot attacks. The presence of a detailed cookie consent banner with categorized cookies supports GDPR compliance efforts. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement in defense-in-depth strategies. No visible incident response or vulnerability disclosure information is provided, which could hinder rapid response to security events. The site does not expose sensitive data or use vulnerable libraries based on the provided data. Overall, the security maturity is adequate for a public utility website but would benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a comprehensive privacy policy and terms of service pages accessible from the main navigation to improve transparency and compliance.
  3. Establish and publicize an incident response contact channel (e.g., security@ or abuse@ email) to facilitate vulnerability reporting and incident management.
  4. Enhance website accessibility features to meet recognized standards and improve user experience for all visitors.
  5. Regularly audit third-party scripts and plugins for security vulnerabilities and update them promptly to maintain a secure environment.

Technical notes

Notes

The website is built on a WordPress CMS platform version 6.8.3, utilizing popular plugins such as Yoast SEO for search engine optimization and CookieYes for cookie consent management. The front-end leverages Bootstrap for responsive design, Font Awesome for icons, and Owl Carousel for interactive content display. JavaScript libraries include jQuery 3.7.1 and Google Tag Manager for analytics integration. Hosting appears to be behind Cloudflare, inferred from cookies and scripts, providing CDN and security benefits. Performance is moderate with asynchronous loading of scripts and preloading of fonts. The site supports multiple languages (French, English, Portuguese) via WPML. Technical debt is low, but improvements in accessibility and security headers are recommended. Overall, the technical infrastructure is modern and well-maintained, supporting a professional user experience.
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.
