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

Entrio.hr is a well-established Croatian online ticketing platform founded in 2011, specializing in ticket sales for concerts, festivals, conferences, exhibitions, and theater performances. It serves both event attendees and organizers, offering a comprehensive digital marketplace for entertainment events primarily in Croatia and nearby regions. The platform integrates social login options and mobile ticketing, positioning itself as a convenient and modern solution in the regional event ticketing market. Technically, the website employs a modern tech stack including AngularJS, jQuery, and Google reCAPTCHA Enterprise, hosted under Plus Hosting Grupa d.o.o. with Cloudflare DNS services, ensuring good performance and security. Security posture is strong with HTTPS enforced and secure form handling, though the absence of a visible cookie consent banner and explicit security policies suggests room for compliance improvement. Overall, Entrio.hr demonstrates a mature digital presence with good business credibility and technical implementation, suitable for its market niche.

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

4 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Entrio.hr operates in the entertainment and event management sector, targeting consumers seeking tickets for a wide variety of events. Its business model revolves around online ticket sales and event promotion, with additional services for event organizers. The company benefits from a consistent brand presence and partnerships with related domains such as entrio.com for corporate and entertainment events. The platform's integration with major ad networks and tracking pixels supports its marketing efforts. Entrio.hr's market position is solid within Croatia, supported by a medium-sized company structure and a domain age consistent with its operational history. The lack of direct contact information on the main site may limit direct customer engagement but is offset by social media presence and user account management features.

Security posture

The website exhibits a strong security posture with HTTPS enforced and use of advanced anti-bot measures like Google reCAPTCHA Enterprise. Security headers are likely implemented, and no sensitive data is exposed in the HTML. However, the absence of a published security policy, incident response plan, or vulnerability disclosure mechanism indicates gaps in transparency and readiness for security incidents. The site uses third-party scripts including Facebook SDK and Google Ads, which require ongoing monitoring for vulnerabilities. Overall, the security maturity is good but could be enhanced by publishing formal policies and improving GDPR cookie consent mechanisms.

Recommendations

  1. Implement a visible cookie consent banner to ensure full GDPR compliance.
  2. Publish a dedicated security policy and incident response information on the website.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

Entrio.hr is built on a modern web technology stack featuring AngularJS and jQuery, supported by libraries such as Dropzone.js and Select2 for enhanced UI components. The site uses Google Fonts and Font Awesome for consistent styling and iconography. Hosting is managed by Plus Hosting Grupa d.o.o. with Cloudflare DNS, providing reliable infrastructure and DNS security. Performance is moderate with good mobile optimization and SEO practices evident from meta tags and structured data. The site lacks a common CMS, indicating a custom or proprietary platform. Technical risks include reliance on multiple third-party scripts which require continuous security monitoring. Opportunities exist to improve accessibility and implement more comprehensive privacy and security controls to align with best practices.
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.
