61/100

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

Portal narodnih knjižnica is a Croatian national library portal established in 2016, providing comprehensive administrative data, digital and regional collections, and library-related news and projects. It serves a broad audience including the general public, researchers, and minority communities in Croatia. The website uses modern web technologies such as Bootstrap, jQuery, and Google Analytics, and implements GDPR-compliant cookie consent mechanisms. The portal is positioned as an authoritative resource in the Croatian library sector with consistent branding and good content quality. Technically, the site is moderately performant and mobile-optimized but lacks explicit security headers and detailed security policies. Security posture is adequate with no visible vulnerabilities or exposed sensitive data, but improvements are recommended in security header implementation and incident response documentation. Overall, the site is trustworthy, safe, and professionally maintained, with a strong alignment between WHOIS registration data and website content.

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

2 findings rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 portal operates as a non-commercial informational service supporting Croatian public and minority libraries. It holds a strong market position as a national reference point for library information and digital collections. The business model focuses on providing free access to library data and facilitating communication between users and librarians. The portal's ecosystem includes partnerships with cultural and educational institutions, as evidenced by linked domains such as hazu.hr and mhk.hr. Growth indicators include ongoing projects and events promotion. The portal's operations emphasize transparency and compliance with data protection regulations, enhancing its credibility and user trust.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage and cookie consent mechanisms in place. However, the absence of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces its defense-in-depth posture. No incident response or security policy pages were found, indicating potential gaps in formal security governance. The use of third-party libraries and analytics tools necessitates regular vulnerability assessments. No exposed credentials or sensitive data were detected, and forms appear to be standard without evident security flaws. Overall, the security posture is adequate but could benefit from enhanced policies and technical controls.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to strengthen browser security.
  2. Publish a dedicated security policy and incident response plan accessible to users and stakeholders.
  3. Conduct regular security audits of third-party libraries and update them promptly to mitigate vulnerabilities.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all audiences.
  5. Maintain transparency by adding terms of service and detailed privacy policies to cover all compliance aspects.

Technical notes

Notes

The website employs a solid technology stack with Bootstrap for responsive design, jQuery for interactivity, and Font Awesome for icons. Google Analytics and Google Tag Manager are used for traffic analysis and marketing insights. The site loads a variety of CSS and JS assets, indicating a moderately complex front-end. Performance is moderate with room for optimization. No CMS was explicitly detected, suggesting a custom or static site architecture. Hosting provider details are not available from the data. The site is mobile-optimized and has basic SEO meta tags but lacks advanced SEO and accessibility features. Technical debt appears low but could be reduced by consolidating scripts and improving security configurations.
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.
