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

The website www.kallaender.ch is a local event listing platform focused on the municipality of Allschwil, Switzerland. Operated by Guidle AG, it provides users with information about upcoming events and allows event organizers to submit their events via a dedicated page. The site targets residents and visitors interested in community activities, positioning itself as a localized event management and information service. The business model revolves around providing a centralized platform for event discovery and submission within the Allschwil community. Technically, the website employs modern web technologies including JavaScript modules, SVG graphics, and the Vite build system. It uses HTTPS to secure communications and loads external scripts from trusted domains such as guidle.com and ajax.googleapis.com. The site is mobile-optimized with responsive design elements and good navigation clarity. However, it lacks some advanced accessibility features and security headers that could enhance its security posture. From a security perspective, the site benefits from HTTPS encryption and does not expose sensitive data in its HTML content. There are no detected vulnerabilities or malicious scripts. However, the absence of security headers like Content-Security-Policy and Strict-Transport-Security, as well as the lack of a cookie consent mechanism, represent areas for improvement. No explicit privacy or security policies are published beyond an impressum page, and no incident response or vulnerability disclosure information is provided. Overall, the website is functional, trustworthy, and serves its community purpose well but would benefit from enhanced privacy compliance and security hardening. Strategic recommendations include implementing cookie consent, publishing detailed privacy and security policies, adding security headers, and considering a vulnerability disclosure program to improve trust and compliance.

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

7 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 · found on this site
  • 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.

Business context

Business profile

Guidle AG operates a niche event listing platform serving the Allschwil community in Switzerland. The company leverages a straightforward business model focused on local event promotion and user-generated event submissions. Its competitive advantage lies in localized content and community engagement. The platform likely generates revenue through partnerships or service fees related to event promotion, although no direct monetization details are visible. The target customers are local residents, visitors, and event organizers. The company maintains a clean digital presence with consistent branding and clear contact information, supporting credibility. Growth potential exists in expanding event coverage or integrating additional community services. The partnership ecosystem includes Guidle AG's own microsite infrastructure. Overall, the business operates with a focused local market approach and moderate digital maturity.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible exposure of sensitive data. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces its defense-in-depth posture. No vulnerability disclosure or incident response information is provided, which limits transparency and preparedness for security incidents. Privacy compliance is partial, with no cookie consent mechanism and only a basic privacy policy accessible via the impressum page. The absence of tracking or analytics scripts reduces privacy risks but also limits user behavior insights. Overall, the security posture is adequate for a low-risk community site but requires enhancements to meet higher compliance and security standards.

Recommendations

  1. Implement a comprehensive cookie consent mechanism to comply with GDPR and other privacy regulations.
  2. Publish detailed privacy and security policies accessible from the main navigation or footer.
  3. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection against common web attacks.
  4. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website uses a modern JavaScript stack with module loading and the Vite build tool, indicating up-to-date front-end development practices. It employs SVG for scalable graphics and jQuery for legacy support. The site is responsive and mobile-friendly, with good SEO meta tags and structured data (JSON-LD BreadcrumbList). External dependencies are limited to trusted domains, reducing third-party risk. Performance is moderate, with some legacy polyfills loaded for compatibility. No CMS or hosting provider information is explicitly detected. The site could improve by adopting additional accessibility standards and optimizing security headers. Overall, the technical infrastructure is solid for a small community platform but has room for modernization and security enhancements.
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.
