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

Digitalna knjižnica Slovenije (dLib.si) is a well-established national digital library platform operated by the National and University Library of Slovenia. It provides comprehensive access to Slovenian cultural heritage materials including books, periodicals, manuscripts, images, music, and maps. The platform targets researchers, students, and the general public interested in Slovenian heritage and digital library resources. The business model is non-profit, focusing on cultural preservation and education. The website is consistent with its mission and has a strong national presence supported by official institutions. Technically, the website is built on ASP.NET Web Forms with a mix of legacy and modern JavaScript libraries such as jQuery, Bootstrap, and Font Awesome. The site is moderately performant with good mobile optimization and basic accessibility features. The use of MathJax indicates support for mathematical content rendering. Hosting appears to be managed by Arnes or the National Library's infrastructure, ensuring stability. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms aligned with GDPR. However, some legacy JavaScript libraries may pose vulnerabilities, and advanced security headers like Content Security Policy are missing. No incident response or security policy pages are published. Overall, the security posture is adequate but could be improved with updates and additional headers. The website is trustworthy, with clear contact via email and social media, and no suspicious or malicious content detected. It maintains a professional design and user experience suitable for its educational and cultural mission. Strategic recommendations include updating JavaScript libraries, enhancing security headers, and publishing formal security and incident response policies to strengthen compliance and 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

8 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

  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

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

dLib.si holds a primary position as Slovenia's national digital library portal, operated by a reputable government-affiliated institution. Its competitive advantage lies in exclusive access to Slovenian cultural heritage digital collections and partnerships with numerous libraries, archives, and museums. The non-profit business model focuses on public service and education rather than revenue generation. The platform serves a niche audience of researchers, students, and cultural enthusiasts. Growth indicators include ongoing content additions and digital exhibitions. The partnership ecosystem is robust, involving national and international cultural institutions. Operationally, the platform relies on legacy ASP.NET technology, suggesting potential modernization opportunities.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforcement and cookie consent compliance. However, the presence of outdated JavaScript libraries (jQuery 1.11.4 and 2.1.4) introduces potential vulnerabilities. The absence of a Content Security Policy and other advanced security headers limits protection against modern web threats. No explicit incident response or security policy documentation is available, indicating gaps in security governance. Data protection practices appear basic but aligned with GDPR through cookie consent and privacy policy presence. The login form is secured via HTTPS but lacks visible multi-factor authentication or advanced protections. Overall, the security posture is functional but requires enhancements to meet higher standards.

Recommendations

  1. Upgrade all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement a comprehensive Content Security Policy (CSP) header to reduce risks of cross-site scripting and data injection attacks.
  3. Add additional security headers such as X-Frame-Options, Referrer-Policy, and X-Content-Type-Options to strengthen browser security.
  4. Publish formal security and incident response policies on the website to improve transparency and preparedness.
  5. Conduct regular security audits and penetration testing focused on ASP.NET Web Forms vulnerabilities and web application security.

Technical notes

Notes

The website is built on ASP.NET Web Forms, a mature but somewhat legacy web framework, combined with front-end technologies like Bootstrap, Font Awesome, and jQuery. The presence of multiple jQuery versions indicates technical debt and potential conflicts. The site uses Owl Carousel for UI elements and MathJax for rendering mathematical content, indicating diverse content types. Performance is moderate, with room for optimization. Mobile responsiveness is good, supported by responsive CSS files. SEO is basic with meta tags and social media cards but lacks advanced structured data like JSON-LD. Accessibility is basic, with some ARIA roles and keyboard navigation support. Hosting is likely managed by Arnes or the National Library infrastructure, ensuring reliability but no explicit CDN or cloud hosting detected.
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.
