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

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 company holds a dominant position in Zagreb's municipal services market, managing a diverse set of subsidiaries that cover energy, transportation, sanitation, and public amenities. Its business model is focused on public service delivery funded and regulated by the city government. The website demonstrates transparency through published procurement plans, corporate governance codes, and financial reports, indicating a mature organizational structure. The presence of multiple social media channels and digital services like mobile apps and online payment portals suggests a commitment to digital transformation and citizen engagement. Partnerships with city portals and waste management entities further strengthen its ecosystem. Growth indicators include ongoing infrastructure projects and positive financial results reported for 2025. The company’s strategic focus appears to be on sustainable urban management and improving service accessibility.

Security posture

The website exhibits a solid security foundation with mandatory HTTPS and cookie consent mechanisms aligned with GDPR requirements. The absence of advanced security headers such as Content-Security-Policy and X-Frame-Options is a minor gap that could be addressed to enhance protection against common web attacks. No signs of exposed credentials, vulnerable libraries, or insecure form handling were found. However, the lack of a published security.txt file and explicit incident response contacts limits transparency in vulnerability reporting and incident management. The use of third-party analytics and sharing tools introduces moderate tracking but appears compliant with privacy standards. Overall, the security posture is good for a public sector website but could benefit from incremental improvements in header policies and incident response visibility.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen web security.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve transparency.
  3. Add explicit incident response contact information on the website to enhance trust and preparedness.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  5. Regularly review and audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance.

Technical notes

Notes

The website uses a combination of custom CSS and JavaScript with libraries such as jQuery, Mapbox, and AddThis for interactive features and analytics. Google Analytics and Google Tag Manager are integrated for user tracking and marketing insights. The site is responsive and optimized for mobile devices, with a moderate performance profile. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting details are not explicitly disclosed, but DNS uses section7.eu name servers. The site has well-structured metadata including Open Graph tags for social sharing. SEO practices are good with clear navigation and content organization. Opportunities exist to improve accessibility and implement modern security headers. Overall, the technical infrastructure supports the business needs effectively with room for modernization in security and accessibility.
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.
