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

Knihovna Matěje Josefa Sychry Žďár nad Sázavou is a well-established public library serving the community with a broad range of lending services including books, magazines, board games, e-books, music, and films. It also organizes cultural and educational events targeting children, adults, and seniors. The library operates as a contributory organization under the city of Žďár nad Sázavou and has a historical legacy dating back to 1848. The website reflects a professional and user-friendly digital presence with clear navigation and comprehensive content relevant to its audience. Technically, the website employs modern web technologies such as jQuery, Bootstrap, Google Fonts, and Google Analytics for tracking. It is mobile-optimized and uses HTTPS for secure communications. The site includes cookie consent mechanisms aligned with GDPR requirements and structured data for enhanced SEO. However, there is room for improvement in security headers and explicit security policy disclosures. From a security perspective, the site demonstrates good practices including HTTPS enforcement and cookie consent management. No critical vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data is likely due to privacy protection, which is reasonable for a public institution. Overall, the site maintains a solid security posture but could benefit from additional transparency in security policies and incident response information. The overall risk assessment is low, with the site providing trustworthy and relevant services to its community. Strategic recommendations include enhancing security headers, publishing security policies, and improving accessibility compliance to further strengthen the site's security and user trust.

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. 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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 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 library holds a strong market position as a regional public institution with a long-standing history and official backing by the city government. Its business model focuses on public service and education rather than commercial revenue. The target audience spans all age groups within the community, including schools and seniors. The website supports this model by offering easy access to catalogs, user accounts, event calendars, and educational resources. Partnerships with regional and national library organizations enhance its service offerings and credibility. The digital presence indicates a commitment to modernization and community engagement, with potential growth in digital lending and online educational programs.

Security posture

The website exhibits a mature security posture with HTTPS enabled and cookie consent mechanisms in place. The use of Google Tag Manager and Analytics is managed with consent controls. No signs of malware, phishing, or exposed credentials were found. However, the lack of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. Security headers such as Content Security Policy and HSTS are not evident and should be implemented to mitigate common web threats. Overall, the site is secure for its purpose but could improve transparency and technical defenses to align with best practices and regulatory expectations.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Establish and publicize a vulnerability disclosure program or security.txt file.
  4. Enhance accessibility features to meet WCAG standards for broader inclusivity.
  5. Regularly audit third-party scripts and dependencies to prevent supply chain vulnerabilities.

Technical notes

Notes

The website is built on a modern technology stack leveraging jQuery, Bootstrap, and Google Fonts, ensuring responsive design and good user experience. The presence of Google Tag Manager and Analytics indicates active user behavior tracking with consent. The site is hosted securely with HTTPS and uses structured data for SEO benefits. Performance is moderate, with potential improvements in loading speed and accessibility. The CMS is not explicitly identified but appears custom or developed by vince.cz. Technical debt is minimal, but security header implementation and accessibility compliance could be improved to reduce risks and enhance user trust.
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.
