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

9 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. 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 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 organization operates in the non-profit sector focused on libraries and cultural heritage. Its business model revolves around membership, project collaboration, and knowledge dissemination. The website showcases a broad partnership ecosystem through projects and events, indicating active engagement in the library community. Revenue streams likely include membership fees, grants, and project funding. The site’s content and structure suggest a medium-sized organization with a stable market position in the Czech Republic. The presence of multilingual content (including English) and international projects like Erasmus+ indicates some international outreach. The organization maintains transparency through published documents and GDPR compliance, enhancing stakeholder trust.

Security posture

The website exhibits a mature security posture with HTTPS enforced and a cookie consent mechanism aligned with GDPR requirements. No critical vulnerabilities or exposed sensitive information were detected in the HTML content. However, the absence of security headers and a published security or incident response policy indicates room for improvement. The use of third-party analytics and social media scripts is managed with opt-out options, reflecting privacy awareness. The site would benefit from implementing additional security headers and publishing a vulnerability disclosure policy to enhance transparency and readiness. Overall, the security posture is good but could be strengthened to meet higher standards.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response plan accessible on the website to improve transparency and preparedness.
  3. Regularly audit and update third-party scripts and plugins to minimize vulnerabilities.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Consider establishing a formal vulnerability disclosure program to encourage responsible reporting of security issues.

Technical notes

Notes

The website is built on a modern and widely used CMS platform, WordPress, enhanced with the Elementor page builder. It integrates Google Analytics and Facebook SDK for analytics and social media engagement, managed via MonsterInsights plugin. The site uses minified CSS and JavaScript for performance optimization and lazy loading for images. Mobile responsiveness and SEO meta tags are well implemented. Hosting details are not explicitly identified, but the domain uses Czech name servers. Performance is moderate, with potential improvements in caching and resource optimization. The technical stack is standard for non-profit organizations, balancing ease of use with functionality. Opportunities exist to modernize security headers and improve accessibility compliance.
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.
