Security score

41/100

Risk levelHigh

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

Muzej Međimurja Čakovec is a well-established regional museum in Croatia, offering a broad range of cultural, historical, and artistic exhibits. The website reflects a mature digital presence with detailed content about museum collections, exhibitions, and educational programs. The institution targets general audiences including tourists, researchers, and local visitors. Technically, the website uses modern web technologies such as Bootstrap, jQuery, and Google Tag Manager, hosted on a Croatian hosting provider. Security posture is adequate with HTTPS enabled but lacks some security headers and formal privacy and cookie policies, which are important for compliance and trust. Overall, the site is professional and trustworthy but could improve privacy compliance and security best 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

11 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 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

      Forces HTTPS connections

      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 · 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 institution under government or public sector auspices, focusing on heritage preservation and education. Its market position is strong regionally with active social media engagement and partnerships with related cultural entities. Revenue streams likely include ticket sales, educational services, and souvenir sales via an e-commerce platform. The museum's digital ecosystem includes virtual exhibitions and transparency portals, indicating a commitment to openness and modern engagement. Growth opportunities exist in enhancing digital accessibility and compliance.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly implemented, and no sensitive data is exposed in the HTML. However, the absence of security headers such as Content-Security-Policy and Strict-Transport-Security reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, which limits transparency and preparedness. Privacy compliance is weak due to missing privacy and cookie policies. The site uses third-party scripts (Google Tag Manager, Mailchimp) which require careful management to avoid privacy risks. Overall, the security posture is functional but could be significantly improved with standard best practices.

Recommendations

  1. Publish a clear and comprehensive privacy policy and cookie consent banner to comply with GDPR and enhance user trust.
  2. Implement standard security headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options) to strengthen security posture.
  3. Create and publish a vulnerability disclosure policy or security.txt file to improve transparency and incident response readiness.
  4. Regularly audit and update third-party libraries and scripts to mitigate vulnerabilities.
  5. Enhance website accessibility features to improve compliance and user experience for all visitors.

Key observations

  1. Website is a well-structured museum site with rich content about exhibitions, collections, and events
  2. No visible privacy or cookie policies found, which is a compliance gap
  3. Contact information is clearly provided with emails, phone numbers, and physical address
  4. Use of modern web technologies and external libraries
  5. No security.txt or vulnerability disclosure found
  6. No signs of adult or questionable content
  7. Social media presence is active and linked
  8. No WAF or blocking mechanisms detected
Technical notes

Notes

The website is built on a solid technical foundation using Bootstrap for responsive design, jQuery for scripting, and integrates external resources like Google Fonts and FontAwesome for styling. Google Tag Manager is used for analytics, and Mailchimp handles newsletter subscriptions. Hosting is provided by Totohost, a Croatian hosting provider, which aligns with the domain's registration. Performance is moderate with no major issues detected, and mobile optimization is good. However, the site lacks advanced SEO and accessibility features, and no CMS is explicitly detected, suggesting a custom or static site architecture. Technical debt appears low but could benefit from modernization in privacy and security implementations.
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.
