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

proust wörter + schönes GmbH operates an independent bookstore located in Essen, Germany, specializing in a curated selection of new and noteworthy books alongside sustainable and beautiful products. The company positions itself as a cultural hub by hosting literary events and readings, targeting book lovers and culturally engaged audiences. Their business model combines physical retail with an online shop, supported by active social media channels and a newsletter subscription service. The website reflects a professional and consistent brand image, emphasizing trust and community engagement. Technically, the website is built on WordPress using the Avada theme and WooCommerce for e-commerce functionality. It employs modern web technologies including jQuery, Slider Revolution, and Borlabs Cookie for GDPR-compliant cookie management. Hosting is managed via INWX, a reputable German provider. The site demonstrates good mobile optimization, accessibility, and SEO practices, contributing to a positive user experience. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms. While some advanced security headers are not explicitly detected, no critical vulnerabilities or exposed sensitive data were found. The WHOIS data aligns well with the business claims, showing consistent domain registration and no privacy protection, which is appropriate for this type of retail business. Overall, the security posture is solid but could be enhanced by adding additional HTTP security headers and publishing a formal security policy. The overall risk assessment is low, with no signs of malicious activity or compliance gaps. Strategic recommendations include strengthening HTTP security headers, maintaining up-to-date software, and considering formal incident response documentation to further enhance trust and resilience.

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

8 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

  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

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

The company operates as a small independent bookstore with a strong cultural orientation, leveraging events and community engagement to differentiate itself in the retail book market. Revenue streams include in-store and online book sales, event hosting, and newsletter marketing. The partnership ecosystem includes cultural organizations such as Literaturgebiet Ruhr and an external online shop platform. The business targets local and regional customers interested in literature and culture, with growth indicators seen in active event scheduling and digital marketing efforts. The website supports these operations with integrated e-commerce and communication tools, reflecting a mature digital presence for a small retail business.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS and GDPR-compliant cookie management via Borlabs Cookie. No exposed credentials or sensitive data were detected in the HTML content. The use of Matomo analytics respects privacy with anonymized data collection. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. There is no visible security or incident response policy, which could be beneficial for transparency and preparedness. Overall, the site maintains a secure environment appropriate for its business scale, with recommendations to enhance header security and formalize security policies.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Maintain regular updates of WordPress core, themes, and plugins to mitigate vulnerabilities.
  3. Publish a clear security policy and provide incident response contact information to improve transparency and readiness.
  4. Enhance monitoring and logging to detect and respond to potential security incidents promptly.
  5. Continue to enforce GDPR compliance and review cookie consent mechanisms periodically to align with evolving regulations.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Avada theme and WooCommerce for e-commerce capabilities. It integrates several JavaScript libraries including jQuery and Slider Revolution for interactive elements. The site uses Borlabs Cookie for cookie management and CleverReach for newsletter services. Hosting is provided by INWX, a German domain and hosting provider. Performance is moderate with good mobile responsiveness and accessibility features. SEO is enhanced by Yoast SEO plugin with proper meta tags and structured data (JSON-LD). Technical risks are minimal but could be reduced by implementing additional security headers and ensuring all third-party plugins are kept up to date.
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.
