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

  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

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 theatre operates in the hospitality and media sectors, focusing on live performances and cultural programming. Its business model centers on event ticket sales, audience engagement through newsletters, and maintaining a strong local presence. The company benefits from a consistent brand and a long operational history, which supports market positioning as a reputable cultural venue in Croatia. Partnerships with local developers and use of multilingual tools indicate a strategy to broaden reach. The absence of direct contact emails but presence of contact forms suggests controlled communication channels. The company does not appear to have subsidiaries or parent companies, indicating an independent operation.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and GDPR compliance evident through cookie policies and consent mechanisms. However, the lack of explicit security headers and absence of a published security policy or incident response contact reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of nonce tokens in AJAX calls is a positive security practice. The site would benefit from enhanced security controls and transparency to improve trust and resilience against attacks.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a security policy and vulnerability disclosure page to improve transparency and incident response readiness.
  3. Regularly audit and update WordPress plugins and themes to minimize vulnerabilities.
  4. Add explicit incident response contact information for security issues.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on a mature WordPress platform with a variety of plugins for enhanced functionality including multilingual support (WPML), event scheduling, social sharing (AddToAny), and newsletter management (SendPress). The site uses jQuery and Slick Carousel for interactive elements. Performance is moderate with room for optimization. Mobile responsiveness is good, and SEO practices are adequately implemented with meta tags and structured navigation. Hosting appears to be stable with domain registration through CARNET, a Croatian academic network registrar. There is no evidence of advanced CDN or security WAF services in use.
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.
