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

BONN LIEST EIN BUCH is a small local cultural initiative based in Bonn, Germany, focused on fostering community engagement through literature and reading circles. The website serves as a platform to share information about the initiative, its activities, and the concept of Wanderbücher (traveling books) circulated within the city. The business model is community-driven, targeting local residents interested in literature and cultural participation. Technically, the website is built on WordPress using the Divi theme and incorporates Yoast SEO for search engine optimization. The site loads Google Fonts and uses standard web technologies. Mobile optimization appears good, and the site structure supports basic accessibility and SEO best practices. However, no advanced frameworks or hosting provider details are explicitly identified. From a security perspective, the website lacks visible security headers and does not present privacy or cookie policies, which are critical for GDPR compliance given its German location. No incident response or vulnerability disclosure mechanisms are evident. The absence of contact information and security policies reduces the overall security posture and privacy compliance. Overall, the website is functional and professionally designed for its purpose but requires improvements in security, privacy compliance, and contact transparency to enhance trust and regulatory adherence.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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

      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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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 initiative positions itself as a community cultural project rather than a commercial enterprise, focusing on literature and reading groups in Bonn. Its competitive advantage lies in local engagement and cultural enrichment rather than commercial services. Revenue streams are not evident, suggesting a non-profit or volunteer-driven model. The target audience is local residents and literature enthusiasts. Growth indicators include the founding year (2021) and ongoing activities. No partnerships or subsidiaries are identified. The website content quality and branding are consistent, supporting a positive community image.

Security posture

The current security maturity level is low due to missing security headers, lack of privacy and cookie policies, and absence of incident response information. No vulnerabilities or exposed sensitive data were detected in the HTML content. Compliance gaps with GDPR are apparent due to missing privacy and cookie notices. The site does not demonstrate readiness for incident response or vulnerability disclosure. Security culture indicators are minimal, reflecting a need for enhanced security awareness and implementation.

Recommendations

  1. Implement comprehensive privacy and cookie policies to ensure GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish clear contact information including emails and phone numbers for transparency and trust.
  4. Establish an incident response plan and publish contact channels for security issues (e.g., security@ or abuse@ emails).
  5. Consider adding a vulnerability disclosure policy and security.txt file to encourage responsible reporting.

Technical notes

Notes

The website uses a standard WordPress CMS with the Divi theme and Yoast SEO plugin, indicating a moderate level of technical maturity. The use of Google Fonts and standard CSS/JS libraries is typical. Performance is moderate with no explicit indicators of optimization or caching mechanisms. Mobile responsiveness is good, but accessibility features are basic. There is an opportunity to modernize by implementing advanced security headers, improving accessibility, and optimizing performance further. No critical technical risks were identified in the provided content.
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.
