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

OeKB CSD GmbH operates as a central securities depository providing critical infrastructure services for the Austrian capital market. The company offers a range of services including digital securities issuance, custody, settlement via the European TARGET2-Securities platform, asset servicing, and payment processing for matured securities. Positioned as a key player within the Austrian financial ecosystem and part of the OeKB Group, it targets capital market participants such as issuers and account holders. The website content is professional, well-structured, and primarily in German with English support, reflecting a medium-sized enterprise with a solid market presence. Technically, the website employs modern web technologies including JavaScript and jQuery, with responsive design elements suitable for mobile devices. While no explicit CMS or hosting provider is identified, the site demonstrates moderate performance and good SEO practices. However, some accessibility features could be improved. Security-wise, HTTPS is enforced, and no obvious vulnerabilities or exposed sensitive data are present. The absence of security headers and explicit security policies suggests room for enhancement in security posture. The WHOIS data is unavailable due to NIC.AT registry restrictions, limiting domain registration transparency. Despite this, the website and business information appear consistent and trustworthy. No blocking or WAF mechanisms were detected, allowing full content access. Privacy compliance is supported by a comprehensive privacy policy and GDPR adherence, though cookie consent mechanisms are lacking. Overall, the site reflects a professional financial services provider with a solid digital presence but could benefit from improved security headers, cookie consent implementation, and enhanced transparency regarding incident response and vulnerability disclosure.

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. 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  2. 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.

Business context

Business profile

OeKB CSD GmbH holds a strategic position as a central securities depository in Austria, serving a niche but critical segment of the financial market. Its business model revolves around providing custody, settlement, and asset servicing for securities, leveraging European infrastructure such as T2S. The company benefits from being part of the OeKB Group, which likely provides financial stability and market reach. The target customers include issuers, account holders, and other capital market participants. The website indicates active engagement with digital asset initiatives and women promotion, signaling progressive corporate values. The absence of direct contact details on the homepage may reflect a controlled client onboarding process typical in financial services. The company’s growth potential is tied to capital market developments and regulatory changes in Europe. Partnerships appear limited to internal group entities and industry associations.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and no visible exposure of sensitive data or vulnerable libraries. However, the lack of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No explicit security policies or incident response contacts are published, which could hinder transparency and trust in case of security incidents. The absence of a security.txt file or vulnerability disclosure program limits external security researcher engagement. Cookie consent mechanisms are missing, which may pose GDPR compliance risks. Overall, the security maturity is moderate but could be significantly improved by adopting standard security headers, publishing security policies, and implementing cookie consent and vulnerability disclosure processes.

Recommendations

  1. Implement standard security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a visible cookie consent banner and detailed cookie policy to ensure full GDPR compliance.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  4. Create and maintain a security.txt file to facilitate responsible vulnerability disclosure.
  5. Enhance website accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website uses a modern front-end stack with JavaScript and jQuery, and responsive design techniques likely based on Bootstrap or similar frameworks. The HTML is well-structured with appropriate meta tags for SEO and social sharing (Open Graph). No JSON-LD structured data was detected, which could be added to improve search engine understanding. Performance appears moderate with no obvious blocking scripts or heavy resources. The site lacks explicit CMS identification and hosting details. Accessibility is basic but could be improved with ARIA roles and better keyboard navigation support. The absence of analytics scripts suggests minimal user tracking, aligning with privacy-conscious practices. Overall, the technical implementation is solid but could benefit from modernization in structured data and accessibility.
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.
