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

3 findings rated critical or high. Fix these first.

  1. 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

  2. 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

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

Markthalle Aarau occupies a niche as a local cultural and social hub in Aarau, leveraging community engagement and sustainability themes. Its business model revolves around event hosting and fostering community exchange programs, supported by Aarau Standortförderung. The organization benefits from partnerships with local initiatives like Madame Frigo and promotes urban gardening. The website content and structure reflect a clear focus on local audiences and community values, with consistent branding and good content quality. The lack of extensive business information such as phone numbers or physical addresses suggests a small-sized entity primarily focused on community rather than commercial scale.

Security posture

The website demonstrates a basic to moderate security posture with HTTPS enforced and no visible sensitive data leaks. However, it lacks important security headers such as Content-Security-Policy and X-Frame-Options, which could improve protection against common web attacks. There is no published security policy or incident response contact, which limits transparency and preparedness. The absence of a vulnerability disclosure policy or security.txt file indicates room for improvement in security maturity. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism, which may pose compliance risks under GDPR. Overall, the security posture is adequate for a small community site but should be enhanced to meet best practices.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection.
  2. Add a cookie consent banner or mechanism to comply with GDPR and other privacy regulations.
  3. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  4. Consider creating and publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built using Webflow CMS and hosted on its CDN, leveraging modern web fonts from Google Fonts and jQuery 3.5.1 for scripting. Google Tag Manager is integrated for analytics and tracking purposes. The site loads with moderate performance and is well optimized for mobile devices. The HTML structure is valid and SEO meta tags are properly set, including Open Graph and Twitter card tags. However, the site lacks advanced accessibility features and some security headers. There is no evidence of server-side technologies or complex backend integrations, indicating a relatively simple technical infrastructure suitable for a small community-focused website.
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.
