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

The website www.oberwil.ch serves as the official digital portal for the municipality of Oberwil in Switzerland. It provides comprehensive information and services to residents, including news updates, event calendars, municipal services, and contact details. The site targets local citizens and stakeholders seeking access to government resources and community information. The business model is centered on public service delivery and community engagement, positioning the municipality as a transparent and accessible local government entity. Technically, the website is built on the iCMS platform, a Swiss municipal content management system, utilizing modern web technologies such as JavaScript, CSS, and HTML5. The site demonstrates good mobile optimization, accessibility, and SEO practices, with moderate performance and a clean, professional design. Hosting is provided by a Swiss provider, ensuring local data handling. From a security perspective, the site uses HTTPS and secure form submissions but lacks explicit security headers and a published security policy or incident response contact. No vulnerabilities or exposed sensitive data were detected. Privacy and cookie policies are present and appear GDPR compliant, with minimal user tracking via Swiss-based analytics. Overall, the website is trustworthy, professional, and well-maintained, suitable for its public service role. Strategic improvements include enhancing security headers, publishing a security policy, and adding vulnerability disclosure information to strengthen security posture 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.

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

Oberwil's municipal website is positioned as a key local government communication and service platform. It leverages digital tools to provide residents with easy access to administrative services, news, and community events. The site supports transparency and citizen engagement, with features like online service counters and subscription-based notifications. The business model is non-commercial, focused on public administration and community support. The presence of social media channels indicates an active outreach strategy. The website's content and structure reflect a mature digital presence for a small municipality, with potential growth in digital service offerings and community interaction.

Security posture

The website exhibits a moderate security maturity level. HTTPS is enforced, and sensitive data exposure is avoided. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No incident response or security contact information is published, limiting transparency in case of security events. The login form uses secure POST methods but lacks visible multi-factor authentication or advanced protections. Privacy compliance is well addressed, but vulnerability disclosure mechanisms are missing. Overall, the site is secure for general public use but could benefit from enhanced security controls and transparency.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options.
  2. Publish a formal security policy and incident response contact information on the website.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance user authentication mechanisms, potentially adding multi-factor authentication for login.

Technical notes

Notes

The website is built on the iCMS platform, a specialized CMS for Swiss municipalities, indicating a tailored solution for government needs. The technology stack includes modern JavaScript modules, CSS, and responsive design elements, ensuring good user experience across devices. The site uses Webpack for asset bundling and includes accessibility features such as ARIA roles and keyboard navigation aids. Performance is moderate, with room for optimization in image delivery and script loading. Hosting is local to Switzerland, supporting data sovereignty. No major technical debts or deprecated technologies were detected, but security header implementation is lacking.
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.
