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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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

  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 serves as a digital front for the municipal government of Muttenz, focusing on delivering public services and information. Its business model is non-commercial, centered on governance and community engagement. The site integrates partnerships with regional and national entities such as Swiss Federal Railways and local development projects, enhancing its service ecosystem. The presence of online forms for login and contact, along with event and news management, indicates a mature digital infrastructure supporting citizen interaction. The absence of commercial advertising and affiliate programs aligns with its public service mandate. Growth indicators include active event promotion and digital service expansion. The partnership ecosystem includes job portals and regional development sites, reflecting a collaborative approach to municipal management.

Security posture

The website maintains a good security baseline with HTTPS encryption and secure form inputs. The use of anonymized analytics with explicit user consent reflects privacy-conscious practices. However, the lack of published security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. No security headers such as Content Security Policy or HSTS were detected, which could enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were found in the HTML content. The site would benefit from formalizing its security posture through documented policies and improved HTTP header configurations to align with best practices and regulatory requirements.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add security HTTP headers including Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options to enhance protection.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance transparency by providing detailed data retention policies related to analytics and user data.

Technical notes

Notes

The website is built on a modern CMS platform (i-web.ch) with a technology stack including JavaScript ES modules and CSS, supported by Bootstrap for responsive design and UI components. The site demonstrates good mobile optimization and accessibility features such as skip links and ARIA labels. Performance is moderate, with optimized images and asynchronous script loading. SEO is supported by meta tags and structured navigation. However, the absence of advanced security headers and limited metadata (e.g., empty Open Graph title and type) suggest areas for technical improvement. Hosting details are not explicitly identified, but the use of Swiss-based analytics and domain registration aligns with local hosting or regional providers.
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.
