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

Knihovny.cz is a Czech Republic-based public library portal operated by Moravská zemská knihovna. It provides a unified platform for searching and accessing the collections of multiple Czech libraries, including digital and printed materials. The portal offers services such as e-book downloads, digital library access, AI-powered book recommendations, and bibliographic citation tools, targeting readers, students, and researchers. The website is professionally designed, mobile-optimized, and offers a user-friendly experience with clear navigation and comprehensive content in Czech language. Technically, it is built on the VuFind platform with Bootstrap and jQuery, integrating Google Tag Manager and reCAPTCHA for analytics and bot protection. Security posture is strong with HTTPS, cookie consent, and session management, though some security headers could be improved. Privacy compliance is well addressed with a clear privacy and cookie policy. However, the absence of WHOIS registration data limits domain trust assessment. Overall, the site is a credible, well-maintained public service portal with moderate risk due to missing domain registration transparency.

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

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 portal holds a key position in the Czech library ecosystem, serving as a centralized access point for library resources nationwide. Its business model is non-commercial, focusing on public service and educational support. The platform leverages partnerships with Czech libraries and the Moravská zemská knihovna as the developer. The presence of AI-based recommendation services indicates innovation and growth orientation. Revenue streams are likely public funding and grants. The target audience includes general public library users, academics, and students. The portal's integration with social media and user feedback mechanisms suggests active community engagement. The lack of explicit contact emails or phone numbers may reflect a preference for web-based communication. The missing WHOIS data is a potential concern for domain legitimacy but does not detract from the portal's operational credibility.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA, and cookie consent mechanisms aligned with GDPR. Security headers such as Content-Security-Policy with nonce are implemented, enhancing protection against XSS attacks. However, some standard headers like X-Content-Type-Options and X-XSS-Protection are not explicitly observed and could be added. No vulnerabilities or exposed sensitive data were detected in the analysis. The absence of a published security policy or incident response contacts is a gap in transparency and readiness. The domain's WHOIS data is unavailable, which may be due to privacy protection or registry policies but reduces trust. Overall, the site is secure for users but could improve transparency and header coverage.

Recommendations

  1. Publish a clear security policy and incident response contact information on the website.
  2. Add missing security headers such as X-Content-Type-Options and X-XSS-Protection to enhance browser security.
  3. Review and tighten Referrer-Policy to a more restrictive setting than 'unsafe-url' to improve privacy.
  4. Investigate and clarify WHOIS registration data to improve domain trust and transparency.
  5. Maintain and regularly update cookie consent and privacy compliance mechanisms to align with evolving regulations.

Technical notes

Notes

The website is built on VuFind 9.1.1, a specialized open-source library resource platform, combined with Bootstrap 3 and jQuery for frontend UI. Google Tag Manager and Google Analytics are used for tracking and analytics, with reCAPTCHA protecting forms from bots. The site uses nonce-based Content-Security-Policy headers, indicating modern security practices. Performance is moderate with asynchronous script loading and deferred JavaScript. The site is mobile optimized and accessible, with ARIA roles and keyboard navigation support. SEO is supported by meta tags and Open Graph data. The absence of explicit hosting provider information limits infrastructure analysis. Overall, the technical stack is appropriate for a public library portal, balancing functionality, security, and user experience.
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.
