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

Zavod za javno zdravstvo Krapinsko-zagorske županije is a regional public health institute serving the Krapina-Zagorje County in Croatia. The organization provides a broad range of public health services including epidemiology, microbiology, health promotion, school medicine, environmental health, and mental health and addiction prevention. The website targets local residents and public health stakeholders, offering news, contact information, and resources relevant to the community. The business model is government-funded, positioning the institute as a key regional health authority. Technically, the website uses a custom ASP-based CMS with legacy JavaScript libraries such as jQuery 1.8.2 and Modernizr, alongside modern UI components like the Revolution Slider and UserWay accessibility widget. The site is moderately optimized for performance and mobile devices, with basic SEO and good accessibility features. However, some technical debt is evident due to outdated libraries and lack of advanced security headers. From a security perspective, the site uses HTTPS and implements cookie consent mechanisms aligned with GDPR requirements. However, the use of outdated JavaScript libraries and absence of security headers like CSP and HSTS present potential vulnerabilities. No explicit security or incident response policies are published. Contact information is clearly provided, enhancing trust and transparency. Overall, the website is professional, trustworthy, and serves its public health mission effectively. Strategic improvements in updating technical components and enhancing security headers would strengthen its security posture and compliance. The site is safe for general audiences with no adult or questionable content detected.

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

  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

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 institute holds a strong regional position as a government public health authority in Croatia, focusing on comprehensive health services for the Krapina-Zagorje County population. Its competitive advantage lies in its official status and broad service portfolio covering epidemiology, microbiology, and mental health. The business model is non-commercial, funded by government budgets, targeting residents, healthcare providers, and public institutions. The website supports community engagement through news updates, social media integration, and public documents. Partnerships with marketing and web development firm Pikant marketing are evident. Growth indicators include active communication and digital accessibility initiatives. The organization maintains a clear and consistent brand aligned with its public health mission.

Security posture

The current security maturity is moderate. HTTPS is enforced, and GDPR compliance is addressed via cookie consent and privacy policy. However, the presence of outdated JavaScript libraries (jQuery 1.8.2) introduces known vulnerabilities that could be exploited. The absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces defense-in-depth. No visible incident response or vulnerability disclosure policies are published, which limits transparency and preparedness. The site does not expose sensitive data in the HTML content. Overall, the security posture is adequate for a public information site but requires modernization and formal security policies to mitigate risks and comply fully with best practices.

Recommendations

  1. Upgrade all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-XSS-Protection, and Strict-Transport-Security.
  3. Publish explicit security and incident response policies to improve transparency and preparedness.
  4. Enhance mobile optimization and SEO to improve user experience and accessibility.
  5. Regularly audit and update privacy and cookie policies to maintain GDPR compliance and user trust.

Technical notes

Notes

The website is built on a custom ASP-based CMS platform with legacy JavaScript libraries such as jQuery 1.8.2 and Modernizr, supplemented by UI components like Revolution Slider and Fancybox. The UserWay accessibility widget is integrated, indicating attention to accessibility standards. The site uses external CDNs for some scripts and styles. Performance is moderate with room for improvement in mobile responsiveness and modern SEO practices. The technical stack shows signs of aging, particularly with outdated libraries that pose security risks. Hosting provider details are not explicitly available. The site structure is clear with consistent branding and navigation, but modernization efforts would benefit overall technical health and security.
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.
