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

The Slovak National Library (Slovenská národná knižnica) is a government cultural institution based in Slovakia, providing extensive library, archival, and museum services. The website serves as a portal for accessing various catalogues, digital libraries, and information about exhibitions and events. It targets a broad audience including the general public, researchers, libraries, publishers, and schools. The institution is well-established with a domain age since 2003 and uses official Slovak government infrastructure for domain management. Technically, the website is built on Joomla CMS with common JavaScript libraries such as jQuery and Mootools, and uses Bootstrap for styling. The site is moderately performant and mobile-optimized with basic accessibility features. SEO is basic but functional. Analytics are implemented via a privacy-conscious service (Plausible Analytics) with minimal user tracking. From a security perspective, the site uses HTTPS and DNSSEC, which are positive indicators. However, no explicit HTTP security headers were detected in the provided data, and there is no published security policy or incident response contact. The cookie policy is present with a consent mechanism, but no privacy policy or terms of service pages were found. Overall, the security posture is moderate with room for improvement. The website content is safe for general audiences, focusing on cultural heritage and educational content without any adult or questionable material. Contact information is clearly provided, including email, phone, and physical address. Social media presence is strong and consistent with the institution's branding. The domain registration data aligns well with the website's claims, supporting high legitimacy and trustworthiness.

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

  2. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Critical

      DNS Resolution Failed

      Unable to resolve domain A records

      What to do: Verify domain is properly configured and not expired

  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 Strict-Transport-Security header

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 Slovak National Library holds a strong national position as the official government library and cultural heritage institution in Slovakia. Its business model is public and government-funded, focusing on providing access to knowledge, cultural preservation, and educational services. The institution leverages partnerships with government bodies and European cultural organizations, enhancing its service offerings and outreach. The website supports multiple user segments including libraries, publishers, schools, and researchers, indicating a diverse target audience. The presence of digital catalogues and online services suggests a strategic focus on digital transformation and accessibility. The institution's long domain history and use of government infrastructure reinforce its credibility and stability in the market.

Security posture

The website demonstrates a moderate security maturity level with HTTPS and DNSSEC enabled, which are essential for secure communications and domain integrity. However, the absence of visible HTTP security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options indicates potential areas for enhancement to protect against common web vulnerabilities. No vulnerability disclosure or security.txt files were found, and no incident response contacts are published, which could limit the institution's ability to handle security incidents effectively. The cookie consent mechanism aligns with privacy best practices, but the lack of a privacy policy page is a compliance gap. Overall, the security posture is adequate for a government cultural site but would benefit from implementing additional security controls and transparency measures.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance web security.
  2. Publish a clear privacy policy and terms of service to improve compliance and user trust.
  3. Establish and publicize a security policy and incident response contact information to facilitate vulnerability reporting and incident management.
  4. Conduct an accessibility audit and improve compliance to ensure inclusivity for all users.
  5. Enhance SEO with structured data (JSON-LD) and meta tags to improve search engine visibility and user experience.

Technical notes

Notes

The website is built on Joomla CMS with a combination of jQuery, Mootools, and Bootstrap CSS frameworks, indicating a mature but somewhat traditional technology stack. The use of Flexslider for image slideshows and custom scripts for UI enhancements shows moderate technical sophistication. The site is mobile-optimized and uses Google Fonts for typography. Performance is moderate, with no major issues detected in the provided content. However, the absence of modern security headers and limited SEO metadata suggests opportunities for modernization. The hosting provider is not explicitly identified, but the use of Slovak government name servers and DNSSEC indicates a secure and official hosting environment. Overall, the technical infrastructure supports the institution's needs but could benefit from updates to security and SEO practices.
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.
