Grad Zagreb is the official governmental entity representing the City of Zagreb, Croatia. The website serves as a comprehensive portal for residents, businesses, and visitors, providing access to city news, administrative information, public services, and digital resources across multiple sectors including education, culture, transportation, social welfare, and urban planning. The site is positioned as the authoritative source for municipal governance and citizen engagement in Zagreb. Technically, the website employs modern web technologies such as Bootstrap, jQuery, and various JavaScript libraries to deliver a responsive and accessible user experience. It integrates Google Analytics for traffic analysis and Kraken Optimize for performance enhancements. The site is mobile-optimized and features clear navigation structures, multi-level menus, and accessibility considerations. From a security perspective, the site enforces HTTPS with a strong SSL configuration and implements cookie consent mechanisms aligned with GDPR requirements. However, explicit security policies and incident response information are not publicly available, and no vulnerability disclosure policy was found.

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

      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

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

Business profile

Grad Zagreb operates as a large governmental organization providing a wide range of public services to its citizens and stakeholders. Its market position is that of the primary municipal authority in Croatia's capital city, offering essential services such as urban planning, social welfare, education, culture, and transportation management. The business model is centered on public service delivery and information dissemination through digital channels. The website supports transparency and citizen engagement by publishing official documents, tenders, and news updates. Partnerships with other governmental and civic organizations are evident through linked domains and service integrations. The presence of multiple online services and digital platforms indicates a commitment to digital transformation and accessibility. Growth indicators include continuous updates, new projects, and active communication channels. The ecosystem includes social media, open data platforms, and specialized portals for various city functions.

Security posture

The website maintains a good security posture with mandatory HTTPS encryption and a valid SSL certificate. Security best practices such as cookie consent and privacy policy compliance are implemented. However, the absence of a publicly available security policy, incident response plan, and vulnerability disclosure mechanism represents a gap in transparency and preparedness. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts is controlled, but continuous monitoring is recommended to mitigate risks from external dependencies. The WHOIS data supports domain legitimacy, reducing phishing or spoofing risks. Overall, the security maturity is moderate to high but could benefit from enhanced documentation and direct security contact channels.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  2. Implement and publicly disclose a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  4. Provide explicit contact channels for security incidents, such as security@ or abuse@ email addresses.
  5. Enhance security headers and perform periodic security assessments to maintain a robust security posture.

Technical notes

Notes

The website is built on a modern technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, and various JavaScript libraries for enhanced UI components like sliders and modals. The CMS appears to be Globaladmin, a custom or specialized CMS used by the site developer. Performance is moderate with asynchronous loading of scripts and use of optimization tools like Kraken Optimize. SEO is well addressed with proper meta tags, Open Graph tags, and structured navigation. Accessibility features are present, including ARIA roles and keyboard navigation support. The site is mobile-optimized and supports multiple languages (Croatian and English). Technical risks are low but include reliance on external scripts and the need for continuous updates to maintain security and performance.
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.
