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

Ljubljanska borza is the official Ljubljana Stock Exchange, serving as the primary capital market infrastructure provider in Slovenia. The website offers comprehensive market data, trading information, and statistical reports targeted at investors and financial professionals. The business is well-established with a domain age dating back to 1995, reflecting its longstanding market presence. Technically, the website employs modern JavaScript frameworks such as Vue.js and integrates essential services like Google Analytics and Google reCAPTCHA with user consent managed via Cookiebot. The site is mobile-optimized and demonstrates good SEO and accessibility practices, although some advanced security headers are not explicitly confirmed. From a security perspective, the site enforces HTTPS and uses a consent management platform to comply with GDPR. However, it lacks publicly available security policies and incident response contacts, which could enhance trust and preparedness. No vulnerabilities or suspicious activities were detected in the analyzed content. Overall, the website presents a professional and trustworthy digital presence for a financial institution, with moderate to good technical maturity and privacy compliance. Strategic improvements in security transparency and contact information publication are recommended to further strengthen its posture.

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

1 finding rated critical or high. Fix these first.

  1. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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

Ljubljanska borza holds a key market position as Slovenia's main stock exchange, providing critical financial market infrastructure and data services. Its business model revolves around operating trading systems, disseminating market data, and offering statistical insights to market participants. The target audience includes investors, brokers, and financial analysts. The company benefits from a consistent brand and a comprehensive navigation structure that supports user engagement. While no parent or subsidiary companies are identified, the exchange maintains partnerships with major service providers like Google for analytics and Cookiebot for compliance. The website content and structure indicate a medium-sized enterprise with a focus on transparency and regulatory compliance.

Security posture

The website demonstrates a solid security foundation with HTTPS enforcement and integration of consent management for cookies, aligning with GDPR requirements. The use of Google reCAPTCHA adds protection against automated abuse. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. Security headers such as Content-Security-Policy and X-Frame-Options are not confirmed, suggesting room for enhancement. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is good but could be improved by publishing formal security documentation and implementing additional HTTP security headers.

Recommendations

  1. Publish a dedicated security policy and incident response contact information on the website.
  2. Implement and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to meet higher standards and improve user experience for all visitors.
  5. Regularly audit third-party scripts and dependencies to mitigate potential security risks.

Technical notes

Notes

The website uses a modern JavaScript stack including Vue.js for interactive charts and Moment.js for date handling. Cookiebot is integrated for GDPR-compliant cookie consent management, and Google Analytics is loaded asynchronously with consent control. The site is mobile responsive and includes multiple favicon sizes for device compatibility. Performance is moderate, with deferred loading of reCAPTCHA and asynchronous analytics scripts. No CMS is explicitly detected, suggesting a custom or proprietary platform. The technical infrastructure supports a professional financial services website but could benefit from enhanced security headers and performance optimizations.
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.
