Risk levelHigh

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

Muzej Sveti Ivan Zelina is a small, government-affiliated cultural institution dedicated to preserving and showcasing the heritage of Sveti Ivan Zelina, Croatia. The website provides detailed information about the museum's history, collections, events, and projects, targeting local visitors, tourists, and cultural enthusiasts. The digital presence is supported by a moderate technology stack including jQuery, Bootstrap, and various UI libraries, with Google Analytics for visitor tracking. The site is mobile responsive and includes accessibility features, enhancing user experience. Security posture is adequate with HTTPS and cookie consent implemented, but lacks advanced security headers and a formal privacy policy, indicating room for compliance improvement. WHOIS data confirms domain legitimacy and consistency with the museum's identity. Overall, the website is professional and trustworthy but could benefit from enhanced privacy and security practices.

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

  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.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • 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

  3. 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

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 · found on this site
  • 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 museum operates as a non-profit cultural entity with a focus on local heritage preservation and education. Its market position is regional, serving the community and visitors interested in Croatian history and culture. The business model relies on public funding and community engagement through exhibitions, events, and publications. The website supports this model by offering virtual exhibitions and newsletters, fostering ongoing visitor interaction. Partnerships appear limited to local transparency initiatives and the hosting provider. Growth potential lies in expanding digital content and improving compliance to meet modern data protection standards.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and cookie consent is present, aligning with GDPR requirements. However, the absence of security headers such as Content-Security-Policy and a security.txt file reduces the overall security posture. No incident response or vulnerability disclosure information is provided, which could hinder timely reporting and mitigation of security issues. The use of multiple third-party JavaScript libraries necessitates regular updates to avoid vulnerabilities. Overall, the site is secure enough for its purpose but should enhance security controls and transparency to strengthen trust and compliance.

Recommendations

  1. Publish a comprehensive privacy policy to improve GDPR compliance and user trust.
  2. Implement security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Create and publish a security.txt file to facilitate vulnerability reporting.
  4. Regularly update all third-party libraries and scripts to mitigate vulnerabilities.
  5. Review and enhance cookie management and data retention policies for transparency.

Technical notes

Notes

The website uses a combination of jQuery, Bootstrap, and several UI-focused JavaScript libraries to deliver a responsive and accessible user experience. Google Fonts and Google Analytics are integrated for design and analytics purposes. The hosting is managed through CARNET with DNS servers at hostingcentar.com, indicating a local Croatian hosting environment. Performance is moderate with no major issues detected, and mobile optimization is good. The site lacks a widely recognized CMS, suggesting a custom or proprietary platform. SEO is basic with minimal meta descriptions and keywords. Accessibility features are implemented, including font size adjustments and high contrast modes. Technical debt is low but could be improved by adopting modern security practices and enhancing SEO metadata.
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.
