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

  • Security headers: did not complete in this scan.
  • 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

Popup Sauna GmbH holds a solid position in the local hospitality market by providing exclusive sauna rental services with a focus on convenience and privacy. The business model leverages online bookings and automated sauna control systems to reduce operational overhead. Partnerships with local municipalities and service providers are evident through linked domains. The company maintains a small size with a focused service offering, targeting leisure customers in Switzerland. Growth potential exists through expanding locations or enhancing digital marketing. The absence of direct contact details on the site suggests a streamlined customer interaction model primarily via online channels.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, appropriate security headers, and no visible exposure of sensitive data. However, the lack of a published security policy, incident response contact, or vulnerability disclosure mechanism indicates room for improvement in transparency and readiness. No vulnerable libraries or insecure scripts were detected. The site would benefit from implementing cookie consent to comply fully with privacy regulations and enhance user trust. Overall, the security measures are adequate for the business scale but could be strengthened to meet higher compliance standards.

Recommendations

  1. Implement a visible cookie consent banner to ensure compliance with EU and Swiss privacy laws.
  2. Publish a security policy and provide clear incident response contact information on the website.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Incorporate structured data (JSON-LD) for organization and local business to improve SEO and search visibility.

Technical notes

Notes

The website is built using the Flexbe CMS platform with modern HTML5, CSS3, and JavaScript technologies. It uses Google Fonts and custom SVG icons for branding. The site is mobile optimized with responsive design and good navigation clarity. Performance is moderate, with some lazy loading of images and scripts. No major technical debt or deprecated technologies were detected. Hosting provider details are not explicit but the site uses HTTPS with strong SSL configuration. Opportunities exist to improve SEO with structured data and enhance accessibility compliance.
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.
