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

Buchknacker is an online library platform operated by the SBS Schweizerische Bibliothek für Blinde, Seh- und Lesebehinderte, targeting children and youth with dyslexia, AD(H)S, and other reading impairments. It offers free access to audiobooks, e-books, and text-audio books, focusing on accessibility and educational support. The platform is positioned as a niche service within the education and non-profit sectors in Switzerland, providing specialized content and services for its audience. Technically, the website employs a moderate technology stack including Dojo Toolkit, jQuery, and Google Tag Manager, running on the Iguana CMS platform. The site is moderately optimized for performance and mobile use, with good accessibility features. SEO practices are adequately implemented with proper meta tags and structured navigation. From a security perspective, the site uses HTTPS and avoids exposing sensitive data. However, it lacks explicit security headers and published security policies or incident response contacts. The absence of a cookie consent mechanism despite using tracking scripts indicates partial privacy compliance. Overall, the security posture is adequate but could be improved with better transparency and controls. The website is trustworthy and professional, with consistent branding and clear business information. No adult or unsafe content is present, making it safe for its intended audience. The domain registration aligns well with the organization, supporting legitimacy. Strategic improvements in privacy compliance and security transparency would enhance the platform's trust and compliance standing.

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. 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';…

  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

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

Buchknacker operates as a specialized online library service under the SBS Schweizerische Bibliothek für Blinde, Seh- und Lesebehinderte, focusing on educational content for children and youth with reading disabilities. Its competitive advantage lies in its niche focus and free access model for users under 18, supported by a reputable Swiss non-profit organization. The business model centers on accessibility and support rather than commercial revenue, likely funded by public or institutional sources. The platform targets a defined user segment with specific needs, leveraging partnerships with content providers and accessibility technologies like ReadSpeaker. The use of Google Tag Manager indicates some level of user behavior tracking for service improvement. Growth potential exists in expanding content and accessibility features. The absence of direct contact emails or phone numbers suggests a controlled communication channel primarily via web forms. Overall, Buchknacker demonstrates a focused mission-driven approach with stable market positioning in the educational non-profit sector, supported by consistent branding and a clear value proposition.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible exposure of sensitive data. The use of Google Tag Manager is implemented asynchronously, reducing performance impact. However, the lack of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No published security policy or incident response contact information limits transparency and readiness communication. No vulnerabilities or outdated libraries were detected from the HTML content, but the presence of older technologies like SWFObject may pose risks if not maintained. Privacy compliance is partial due to missing cookie consent mechanisms despite tracking scripts. Overall, the security posture is functional but would benefit from enhanced policies, headers, and privacy controls to meet higher compliance standards such as GDPR and NIS2.

Recommendations

  1. Implement a comprehensive cookie consent banner to comply with GDPR and inform users about tracking.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add security headers including CSP, HSTS, and X-Frame-Options to improve protection against common web attacks.
  4. Regularly update and audit third-party libraries and scripts to mitigate vulnerabilities.
  5. Enhance privacy compliance by documenting data retention policies and providing user data control options.

Technical notes

Notes

The website is built on Iguana CMS version 6.0.01 with a front-end leveraging Dojo Toolkit and jQuery libraries. Google Tag Manager is used for analytics and tracking, and ReadSpeaker webReader provides accessibility features. The site uses asynchronous script loading to optimize performance. Mobile optimization is basic but functional, with responsive design elements. No major technical debt is evident, but the presence of legacy technologies like SWFObject suggests some modernization opportunities. SEO is supported by proper meta tags and Open Graph data. Accessibility is addressed through ReadSpeaker integration and font size controls. Hosting provider details are not explicitly identified. Overall, the technical infrastructure is stable with room for modernization and enhanced security hardening.
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.
