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. 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

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

The website targets residents, businesses, and visitors of Illnau-Effretikon, offering key municipal services including online administrative procedures, official publications, and event information. Its business model is non-commercial, focused on public service delivery. The site benefits from consistent branding and a clear organizational structure, supporting effective communication and community engagement. Partnerships with local organizations and external cultural sites are evident, enhancing the city's community presence. The domain and WHOIS data confirm legitimacy and long-term establishment, supporting trust and credibility.

Security posture

The website maintains a good security baseline with HTTPS and secure login forms. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options represents an area for enhancement. No vulnerabilities or exposed sensitive data were detected in the content. The lack of a published security policy or incident response contact limits transparency and preparedness visibility. Privacy compliance is incomplete due to missing cookie consent mechanisms, which could expose the site to regulatory risks under GDPR. Overall, the security posture is adequate but could be strengthened with targeted improvements.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Deploy a visible cookie consent banner to ensure compliance with GDPR and other privacy regulations.
  3. Publish a dedicated security policy and incident response contact information to enhance transparency and trust.
  4. Regularly review and update third-party scripts and analytics tools to avoid vulnerabilities.
  5. Enhance privacy policy details to explicitly address data retention and user rights.

Technical notes

Notes

The website is built on the i-web CMS platform, leveraging modern JavaScript modules, Bootstrap for responsive design, and Matomo for analytics. It uses asynchronous script loading to optimize performance. The site is mobile-optimized and accessible, with clear navigation and structured content. Hosting appears to be managed by i-web.ch, a Swiss hosting provider. Performance is moderate, with potential for improvement through optimization of image assets and script loading strategies. The technical stack is well-suited for a municipal website, balancing functionality and maintainability.
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.
