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

Bücher Eule is a small, specialized antiquarian bookshop and bookstore based in Bern, Switzerland. The business focuses on providing a curated selection of antiquarian and modern books, serving readers and collectors primarily in the Swiss market. Their website offers a comprehensive catalog, search functionality, and additional services such as newsletters and collector software, positioning them as a niche player in the retail book industry. The company maintains an active social media presence and clear contact channels, enhancing customer engagement and trust. Technically, the website is built on a custom CMS framework (HESCOM Web Framework) and uses technologies like jQuery and Shariff for social sharing. The site is moderately performant with good mobile optimization and basic accessibility features. SEO practices are adequately implemented with proper meta tags and structured navigation. Analytics are handled via Matomo, indicating some privacy-conscious tracking. From a security perspective, the site uses HTTPS and secure form submissions but lacks visible security headers and a cookie consent mechanism, which are areas for improvement. No explicit security or incident response policies are published, which could impact compliance and customer trust. The WHOIS data aligns well with the business claims, supporting legitimacy. Overall, the site is professional and trustworthy but could enhance its security posture and privacy compliance. Strategically, Bücher Eule should prioritize implementing security headers, cookie consent, and publishing security policies to improve compliance and user trust. Regular security audits and updates to third-party libraries will further strengthen their security stance. Enhancing privacy compliance will also align the business with GDPR requirements, important for their European customer base.

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

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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

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 · 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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Bücher Eule operates in the niche antiquarian book retail sector, targeting readers and collectors interested in rare and modern books. Their business model combines online and physical retail, supported by a detailed online catalog and search tools. The company leverages partnerships with HESCOM for their webshop platform, indicating a reliance on specialized software providers. Their social media presence and newsletter offerings suggest active customer engagement strategies. The business appears stable and well-positioned within the Swiss market, with a focus on quality and specialized inventory rather than mass retail. Revenue streams likely include direct book sales and software-related services for collectors. Growth potential may be limited by niche market size but can be enhanced through digital marketing and expanded catalog offerings.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is in use, and forms employ POST methods, reducing exposure to basic attacks. However, the absence of security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS reduces protection against common web vulnerabilities. No security or incident response policies are published, indicating a gap in transparency and preparedness. The use of Matomo analytics suggests some privacy awareness, but lack of cookie consent mechanisms may expose the business to GDPR compliance risks. No vulnerabilities or exposed sensitive data were detected in the content. Overall, the security posture is functional but requires enhancements to meet best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Add a cookie consent banner/mechanism to comply with GDPR and enhance user privacy transparency.
  3. Publish a clear security policy and incident response contact information to improve trust and preparedness.
  4. Regularly update and audit third-party libraries and scripts to reduce vulnerability risks.
  5. Conduct a full security audit focusing on input validation and data protection to strengthen overall security posture.

Technical notes

Notes

The website is built on a proprietary CMS platform (HESCOM Web Framework) with front-end technologies including jQuery and Shariff for social sharing. The site is moderately performant with good mobile responsiveness and basic accessibility features. SEO is well addressed through meta tags and structured navigation. Hosting details are not explicit but analytics are served from hescomshop.com, indicating a specialized hosting or service provider relationship. The site uses HTTPS but lacks advanced security headers. Forms use POST methods but no advanced anti-CSRF or input sanitization mechanisms are visible. Overall, the technical infrastructure is stable but could benefit from modernization and enhanced security controls.
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.
