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 serves as the digital front for the city government of Langenthal, Switzerland, focusing on public administration and citizen engagement. Its business model is non-commercial, centered on providing transparent access to municipal services and information. The site integrates partner services for job applications, moving registrations, and building permits, indicating a collaborative ecosystem. The target audience includes residents, local businesses, and visitors. The presence of newsletters and online service portals suggests ongoing efforts to enhance digital service delivery. The site’s market position is that of a trusted government portal with a medium-sized operational scope.

Security posture

The website demonstrates a solid security foundation with HTTPS encryption and secure login forms. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The use of Matomo analytics respects user privacy with consent mechanisms. However, the absence of explicit security headers like Content-Security-Policy and a public security policy or incident response contact reduces the overall security maturity. There is no visible vulnerability disclosure or security.txt file. The site would benefit from publishing a formal security policy and enhancing HTTP security headers to mitigate risks further.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  2. Publish a dedicated security policy page and provide incident response contact information.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities.
  5. Enhance transparency around data retention policies for analytics and user data.

Technical notes

Notes

The website is built on the i-web CMS platform, utilizing modern JavaScript modules and CSS precompiled assets. It employs Matomo for analytics, ensuring privacy-conscious tracking with user consent. The site is mobile-optimized and accessible, with clear semantic HTML structure and ARIA landmarks. Performance is moderate, with asynchronous loading of analytics scripts. The site uses multiple modals for login, contact, and search, indicating interactive user experience design. There is no evidence of legacy or deprecated technologies. Opportunities exist to improve technical SEO and security headers for enhanced robustness.
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.
