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

Moravská zemská knihovna v Brně operates as a regional public library institution in the Czech Republic, offering extensive library services including lending, interlibrary loans, digital catalogs, educational programs, and cultural events. The website is professionally designed using Drupal 10, featuring a rich content structure and good user experience optimized for mobile devices. Security posture is strong with HTTPS and security headers implemented, though privacy and cookie policies are not explicitly visible, indicating room for compliance improvement.

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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  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 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';…

  3. 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.

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 regional position as a key educational and cultural institution in Brno, serving multiple audiences including the public, schools, and librarians. Its business model is public service funded by government resources. The website supports various services such as user registration, event calendars, and digital resource access, indicating a comprehensive service ecosystem. Partnerships with cultural and educational entities are evident through linked domains. The site’s content quality and branding consistency reinforce its credibility and trustworthiness in the education sector.

Security posture

The website employs HTTPS with good SSL configuration and security headers such as HSTS, CSP, and X-Frame-Options, enhancing protection against common web attacks. Secure login mechanisms are in place for user accounts. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of publicly available security policies, incident response contacts, or vulnerability disclosure mechanisms suggests an opportunity to improve transparency and readiness. Cookie consent is implemented, but explicit privacy policy documentation is missing, which may affect GDPR compliance.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy clearly accessible on the website.
  2. Add terms of service and security policy pages to improve transparency and user trust.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file.
  4. Enhance contact information visibility, including security and data protection officer contacts.
  5. Regularly review and update WHOIS registration data to ensure domain registration transparency.

Technical notes

Notes

The website is built on Drupal 10 CMS, leveraging modern JavaScript libraries such as Swiper.js for UI components and Google Tag Manager for analytics. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate, with asynchronous loading of scripts and optimized images. SEO best practices are followed with proper meta tags and structured navigation. No critical technical debt or outdated technologies were observed, indicating a well-maintained infrastructure. Hosting provider details are not explicitly identified from the 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.
