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

The website www.corsier.ch serves as the official digital presence of the municipal government of Corsier, Switzerland. It provides residents and visitors with comprehensive information about local government services, community news, events, administrative procedures, and social and cultural activities. The site targets local citizens and stakeholders, offering a centralized platform for accessing municipal resources and updates. The business model is that of a public sector entity focused on community service and governance. Technically, the site is built on the i-web.ch CMS platform, utilizing modern web technologies including JavaScript, CSS, and HTML5. The website demonstrates good mobile optimization, accessibility, and SEO practices. Performance is moderate, with a clean and professional design that supports clear navigation and user experience. The site employs HTTPS and anonymized web statistics, reflecting a reasonable level of digital maturity. From a security perspective, the website enforces HTTPS and avoids exposing sensitive data. However, it lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or malicious content were detected. Privacy compliance is supported by a clear privacy and cookie policy with consent mechanisms, aligning with GDPR requirements. Business credibility is high due to transparent contact information and consistent branding. Overall, the website presents a low-risk profile with strong legitimacy as a government entity. Strategic recommendations include enhancing security headers, publishing incident response and vulnerability disclosure policies, and improving advertising transparency. These steps would further strengthen the security posture and trustworthiness of the site.

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. 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';…

  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 SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Corsier's municipal website positions itself as a key local government portal, providing essential services and information to its community. Its competitive advantage lies in its comprehensive coverage of municipal functions, from administrative services to cultural and social activities. The business model is non-commercial, focused on public service delivery. Revenue streams are not applicable, as it is a government entity. The target customer segment is local residents and visitors seeking municipal information. Growth indicators include regular content updates and event listings. The partnership ecosystem is limited but includes the CMS provider i-web.ch. Strategic observations highlight the importance of digital transformation in local governance and the need for continuous security and privacy enhancements.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and no visible sensitive data leaks. The absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents a gap that could be exploited. There is no published incident response or vulnerability disclosure policy, which limits transparency and preparedness. Data protection practices are evident through anonymized analytics and a privacy policy compliant with GDPR. The site lacks explicit contact channels for security incidents, which could delay response times. Overall, the security culture appears basic but functional, with room for improvement in formalizing policies and technical defenses.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a clear incident response policy and provide dedicated contact channels for security issues to improve transparency and readiness.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security flaws.
  4. Enhance cookie consent mechanisms to provide more granular user control and transparency.
  5. Conduct regular security audits and update third-party libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on the i-web.ch CMS platform, leveraging standard web technologies such as JavaScript, CSS, and HTML5. The technical infrastructure supports responsive design and accessibility features, contributing to a positive user experience. Performance is moderate, with no significant issues detected. The site uses anonymized web statistics hosted on stats.i-web.ch, indicating a privacy-conscious approach to analytics. There is no evidence of outdated or vulnerable libraries. Opportunities exist to modernize security configurations and improve SEO metadata completeness. Technical risks are minimal but should be addressed through ongoing maintenance and security enhancements.
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.
