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 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

Studenac holds a strong market position as a major retail chain in Croatia, leveraging a large physical footprint and digital engagement through its mobile app and online catalogs. Its business model focuses on retail sales augmented by loyalty programs and value-added services. The company benefits from ownership by a reputable investment fund, indicating financial stability and growth potential. Partnerships with delivery services and lottery providers diversify its offerings. The website's integration with social media and clear contact channels supports customer engagement and brand loyalty. Growth indicators include a large employee base and extensive store network. Strategic observations suggest continued investment in digital tools and customer experience will sustain competitive advantage.

Security posture

The website demonstrates a good security baseline with HTTPS and cookie consent mechanisms in place. Use of Google Tag Manager is properly asynchronous, reducing performance and security risks. However, the absence of explicit security policies, incident response contacts, and security headers indicates room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. Compliance with GDPR is evident through privacy policy and cookie management. The security culture appears adequate but could be enhanced by publishing vulnerability disclosure policies and implementing additional HTTP security headers to mitigate common web threats.

Recommendations

  1. Publish a dedicated security policy and incident response information on the website.
  2. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Regularly audit and update third-party scripts to minimize vulnerability risks.
  4. Consider adding a security.txt file or vulnerability disclosure program to encourage responsible reporting.
  5. Enhance transparency around data retention policies and user privacy controls.

Technical notes

Notes

The website uses a modern front-end technology stack including jQuery, GSAP for animations, Swiper for sliders, and Google Fonts for typography. Google Tag Manager is integrated for analytics and marketing tags. The site is mobile-optimized with responsive images and layouts. Performance is moderate with asynchronous script loading and minimal blocking resources. No CMS is explicitly detected, suggesting a custom or proprietary platform. Accessibility features are present but could be further enhanced. SEO is supported by comprehensive metadata, Open Graph tags, and structured JSON-LD data. Technical risks are low, but ongoing maintenance of third-party libraries and security headers is recommended to maintain robustness.
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.
