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

Active City is a Swiss-based community initiative offering free sports and movement courses for all age groups, promoting outdoor and collective physical activities without registration requirements. The website is professionally designed using Umbraco CMS and integrates modern technologies such as Google Tag Manager, reCAPTCHA, and Cookiebot for privacy compliance and user experience enhancement. The technical infrastructure supports good performance and mobile optimization, with a moderate level of accessibility and SEO optimization. Security posture is solid with HTTPS enforcement and cookie consent management, though some security headers could be improved and explicit security policies are absent. Overall, the website is trustworthy, transparent, and well-aligned with its community service mission.

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

1 finding 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.

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 the general Swiss population interested in free, accessible sports activities, positioning itself as a local non-profit community service. Its business model focuses on public engagement and health promotion rather than commercial revenue. The use of multiple external domains related to partner organizations and service providers indicates a collaborative ecosystem. The absence of explicit privacy and terms policies suggests room for maturity in compliance documentation. The company behind the site, OPTEN AG, is a recognized entity, adding credibility. The site’s marketing and analytics tools are standard for community outreach and user engagement measurement.

Security posture

The website demonstrates a good security baseline with HTTPS and cookie consent mechanisms. It employs Google reCAPTCHA to mitigate bot traffic and uses Cookiebot for GDPR-compliant cookie management. However, the lack of explicit security headers like Content-Security-Policy and absence of published security or incident response policies represent gaps. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The WHOIS data is consistent and transparent, supporting domain legitimacy. To enhance security posture, the site should implement additional HTTP security headers and publish clear security policies and incident response contacts.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a detailed privacy policy and terms of service accessible from the website footer or main navigation.
  3. Add a security policy and incident response contact information to improve transparency and readiness.
  4. Conduct regular audits of third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a modern technology stack with Umbraco CMS, Google APIs, and popular JavaScript libraries for UI and map functionalities. Performance is moderate with asynchronous loading of scripts and lazy loading of images. The site is mobile optimized and includes SEO-friendly meta tags and Open Graph data. Cookie consent is managed by Cookiebot, ensuring compliance with privacy regulations. Hosting details are not explicitly found but the use of Google services and CDN resources suggests a reliable infrastructure. Opportunities exist to improve accessibility and security header implementation to reduce technical risks.
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.
