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

Lüthy Balmer Stocker operates buchhaus.ch, a Swiss-based online bookstore offering over 15 million books, e-books, games, and media products. The business combines e-commerce with physical retail presence, allowing customers to pick up orders at 23 store locations across Switzerland. The website is professionally designed with good navigation and mobile optimization, targeting general book readers and media consumers in the Swiss market. Technically, the site uses modern JavaScript libraries including jQuery, Google Maps API, and barcode scanning tools, indicating a mature digital infrastructure. Security posture is strong with HTTPS enforced and secure login forms, though some security headers are missing and privacy compliance could be improved by adding visible privacy and cookie policies. No blocking or WAF interference was detected, and WHOIS data confirms the domain's legitimacy and consistency with the business. Overall, the site is trustworthy and functional but would benefit from enhanced privacy disclosures and contact information visibility.

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

2 findings rated critical or high. Fix these first.

  1. 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

  2. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 company is positioned as a significant player in the Swiss retail book market, leveraging both online and physical channels. Its extensive catalog and multiple store locations provide competitive advantages. The business model focuses on direct sales and customer convenience through in-store pickup and delivery. The website's content and structure support a broad target audience including general readers and specialized book buyers. While no explicit revenue data is available, the scale of offerings and infrastructure suggest a medium-sized enterprise with stable market presence. The lack of visible partner or subsidiary domains indicates a focused business operation. Marketing tools are minimal, relying mainly on organic search and direct customer engagement.

Security posture

The website demonstrates a good security baseline with HTTPS and secure form handling. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense in depth. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The site lacks explicit incident response or vulnerability disclosure information, which could improve transparency and trust. Privacy compliance is weak due to missing privacy and cookie policies, potentially exposing the business to regulatory risks under GDPR. The session timeout warning is a positive security feature. Overall, the security posture is solid but could be enhanced with additional headers and compliance documentation.

Recommendations

  1. Publish and prominently link a comprehensive privacy policy and cookie policy to improve GDPR compliance and user trust.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen security posture.
  3. Add explicit contact information including company emails and phone numbers for customer support and incident response.
  4. Introduce a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Enhance accessibility features to meet standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a custom or proprietary e-commerce platform with modern JavaScript libraries including jQuery 3.7.0, Google Maps API, and barcode scanning tools. The site is mobile optimized and includes features such as session timeout warnings and advanced search with suggestions. Performance is moderate with preloading of CSS and JS assets. SEO is supported by meta tags, canonical links, and alternate language versions. No CMS like WordPress or Magento was detected, indicating a tailored solution. Hosting provider details are not explicit. The technical stack is stable but could benefit from enhanced security headers and performance optimizations.
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.
