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

openCity Hrvatska is a Croatian public sector project aimed at promoting the opening of public sector data in line with EU standards. The website provides interactive visualizations to make public information easily understandable for citizens. The project targets Croatian government entities and the general public interested in transparent data access. The business model focuses on government data transparency and public engagement through digital tools. The website is relatively small in scale, founded in 2018, and hosted by Plus Hosting Grupa d.o.o. The content is primarily in Croatian and is professionally presented with good navigation and mobile optimization. Technically, the website uses modern web technologies including HTML5, CSS3, JavaScript, jQuery, CartoDB, and Leaflet for mapping. It integrates Google Analytics and Facebook SDK for analytics and social media engagement. Hosting is provided by a Croatian registrar consistent with the domain registration data. Performance is moderate with room for improvement in accessibility and SEO. From a security perspective, the site uses HTTPS and avoids exposing sensitive data. However, it lacks important security headers and formal security policies such as incident response or vulnerability disclosure. Privacy compliance is weak due to the absence of privacy and cookie policies or consent mechanisms. The WHOIS data is consistent and indicates a legitimate registration aligned with the website's purpose. Overall, the website is functional and trustworthy for its niche but should improve privacy compliance and security best practices to enhance user trust and regulatory adherence.

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

10 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

      Missing X-Frame-Options header

      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, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The project occupies a niche position in the Croatian government and public sector transparency market. It leverages open data initiatives aligned with EU standards, targeting citizens and public institutions. The platform's competitive advantage lies in its interactive visualizations and focus on Croatian public data. Revenue streams are not explicit but likely stem from government or public funding. The partnership ecosystem includes hosting by Plus Hosting Grupa d.o.o. and integration with major analytics and social platforms. Growth indicators are limited but the project appears stable since 2018. Strategic observations suggest potential expansion through enhanced privacy compliance and broader public engagement.

Security posture

The website demonstrates a basic security maturity level with HTTPS enabled and no visible sensitive data leaks. However, it lacks critical security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate common web attacks. There is no public incident response or vulnerability disclosure information, limiting transparency in security management. Privacy compliance is insufficient, with no privacy or cookie policies, which may expose the project to regulatory risks under GDPR. The use of third-party libraries like jQuery and Facebook SDK requires regular updates to avoid vulnerabilities. Overall, the security posture is moderate but requires enhancements to meet best practices and compliance standards.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to improve protection.
  3. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance accessibility features to improve usability for all users.
  5. Regularly audit and update third-party libraries and scripts to mitigate vulnerabilities.

Technical notes

Notes

The website is built on a solid technical foundation using standard web technologies and modern mapping libraries like Leaflet and CartoDB. It integrates Google Analytics and Facebook SDK asynchronously to optimize performance. Hosting is provided by a local Croatian provider consistent with domain registration. The site is mobile optimized and has good navigation clarity. However, there is room for improvement in SEO and accessibility compliance. Performance is moderate, potentially impacted by multiple external scripts. No CMS is detected, indicating a custom or static site architecture. Technical risks include missing security headers and potential outdated third-party libraries.
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.
