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

NIMBUS. Kunst und Bücher is a small Swiss publishing house specializing in art, contemporary photography, and literature. The company offers a curated selection of high-quality books and organizes cultural events such as exhibitions and readings. Their website provides comprehensive information about their offerings, authors, and events, targeting art and literature enthusiasts. The business operates with a niche focus and maintains a professional online presence with clear contact details and social media links. Technically, the website is built on Drupal 7 with common web technologies like jQuery and Superfish menus. While the site is functional and moderately optimized, it shows signs of aging technology and lacks advanced mobile optimization and accessibility features. The hosting provider is hosttech GmbH, a known Swiss hosting company. Performance is moderate, and SEO practices are basic. From a security perspective, the site uses HTTPS but lacks visible security headers and cookie consent mechanisms, which are important for GDPR compliance. No incident response or vulnerability disclosure policies are evident. The use of an older CMS version may pose security risks if not properly maintained. Overall, the security posture is average with room for improvement. The overall risk is moderate; the site appears legitimate and professional but should enhance security and privacy compliance to reduce potential vulnerabilities and improve user trust. Strategic recommendations include updating the CMS, implementing security headers, adding cookie consent, and improving mobile and accessibility features.

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

6 findings 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.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  2. 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

  3. 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

NIMBUS occupies a niche market in Swiss publishing focused on art, photography, and literature. Their competitive advantage lies in specialized content and cultural event hosting, which strengthens community engagement. Revenue streams likely include book sales and event participation. The target customers are culturally engaged individuals and collectors. The company maintains partnerships, such as with swips.ch, and leverages social media for outreach. Growth indicators are not explicit but the presence of a newsletter and event calendar suggests active engagement. The business model is traditional publishing supplemented by events and direct customer interaction.

Security posture

The website demonstrates a basic security maturity level. HTTPS is enabled, ensuring encrypted communication. However, the absence of security headers like Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No cookie consent or privacy policy transparency is evident, which may lead to GDPR compliance issues. The use of Drupal 7, an outdated CMS, could expose the site to known vulnerabilities if not regularly patched. No incident response or vulnerability disclosure mechanisms are in place, limiting the ability to handle security incidents effectively. Overall, the security culture appears minimal but not negligent.

Recommendations

  1. Upgrade Drupal CMS to the latest supported version to mitigate known vulnerabilities.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a cookie consent banner and detailed cookie policy to comply with GDPR requirements.
  4. Establish an incident response plan and publish contact information for security issues.
  5. Enhance mobile responsiveness and accessibility to improve user experience and compliance.

Technical notes

Notes

The website uses Drupal 7 CMS with jQuery and Superfish for UI components, indicating a traditional web stack. Hosting is provided by hosttech GmbH, a reputable Swiss provider. The site loads CSS and JS resources from its own domain and Google Fonts, with no heavy third-party analytics or tracking scripts detected, which benefits privacy. Performance is moderate but could be improved with modern front-end optimizations. The site lacks advanced SEO and accessibility features, and mobile optimization is basic. Technical debt is present due to the older CMS version and missing modern security practices.
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.
