Wiener Börse AG operates as Austria's primary stock exchange, providing a platform for trading equities, bonds, certificates, ETFs, and options. The website serves investors and financial market participants with up-to-date market data and index information such as the ATX. The company holds a significant market position within Austria's financial sector, focusing on transparency and accessibility. Technically, the website is built on TYPO3 CMS with Bootstrap, integrating modern web technologies and accessibility tools to ensure compliance with diverse user needs. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though explicit security headers and policies are not fully visible.

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

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Wiener Börse AG is positioned as a key financial market infrastructure provider in Austria, catering to institutional and retail investors. Its business model revolves around operating a regulated trading venue and providing market data services. The company likely generates revenue through transaction fees, listing fees, and data sales. The website's multilingual support and comprehensive market information indicate a strategy to serve both domestic and international clients. The integration of accessibility features reflects a commitment to inclusivity. The lack of visible contact details and privacy policies on the main page suggests areas for improvement in transparency. The company appears to maintain partnerships with major technology and analytics providers such as Google and Cookiebot, enhancing its digital ecosystem.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and integration of cookie consent tools, indicating GDPR awareness. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not confirmed in the provided data, representing potential areas for enhancement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of publicly available security policies or incident response contacts limits transparency and readiness perception. The accessibility tool integration is a positive security and usability feature. Overall, the site is secure but could benefit from more visible security governance documentation and header implementations.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the homepage footer.
  2. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear contact information including security incident response and data protection officer contacts.
  4. Enhance WHOIS transparency or provide domain registration details on the website to improve trust.
  5. Regularly audit third-party scripts and tracking tools to ensure compliance and security.

Technical notes

Notes

The website is built on TYPO3 CMS with Bootstrap, leveraging modern web fonts and icons for a professional look. It uses Google Tag Manager and Google Analytics for tracking, and Cookiebot for cookie consent management. The site is mobile-optimized and includes extensive accessibility features, including a dedicated accessibility tool with multiple profiles and customization options. Performance appears moderate with preloading and preconnect hints for critical resources. No hosting provider or server details were identified from the HTML. The site lacks visible structured data (JSON-LD) for SEO enhancement. Overall, the technical implementation is solid with room for improvement in SEO structured data and security header deployment.
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.
